Castrol Edge vs Mobil 1 – Which Motor Oil Is Best For You?

by Conner Mckay

Castrol Edge vs Mobil 1? Picking the best synthetic oil for your car, truck, or even motorcycle can be somewhat challenging. Not everyone has adequate knowledge of oil blends to make the right decision. Besides, there is a myriad of choices on the market today, and between all these oils, they’re all rather good.

Consumers tend to stick to well-known, trusted brands to reduce the overall hassle. After all, we only want what’s best for our cars and automotive fluids aren’t where you should start skimping. In most cases, the pick boils down to two names: Castrol Edge and Mobil 1.

These two high-quality oil varieties have been around for almost decades now. Both brands are subsidiaries of the biggest international oil companies. Today, we’re getting into a thorough comparison between Castrol Edge vs Mobil 1 to figure out which one is the best…

In these comparisons, we’ll be looking at whether Castrol Edge or Mobil 1 is right for your car. We’ll then get into the nitty-gritty of the differences between them. In addition, we’ll also detail the processes of how to change your own engine oil, and the top motor oil brands out there.

Motor Oil Types

Castrol Edge vs Mobil 1

The main ingredients in an oil manufacturing process decide the kind of motor oil it is. Despite going through a series of changes that takes away their actual “true” petroleum status, full synthetic oils are still considered as “pure” petroleum.

Generally, based on petroleum content, motor oils can be divided into three categories. If an oil consists of a singular petroleum base those are called conventional motor oils.

On the other hand, full synthetics aren’t laced with true petroleum mixes. These blends feature a combination of two types. Not necessary for the mixture to be in a 1:1 ratio. This typically varies between brands.

Castrol Edge vs Mobil 1 – both are heavy on the use of synthetic products in their oil blends.

1. Full Synthetic

Car owners love full synthetic oils and they have a bunch of good reasons for it. In comparison to synthetic and conventional blends, full synthetic oil definitely takes the cake in all performance aspects.

The only thing that can be considered a big issue is compatibility. You can only use these oils in new cars and some of the older models of vehicles might not be compatible.

But with the gradual development of synthetic oil technology, this is changing as well. If synthetic oils are compared in Castrol Edge vs Mobil 1, the latter has an upper hand in this department as the brand focuses more on that part.

2. Synthetic Blend

A synthetic blend is what the name suggests – a blend. It’s a combination of ingredients from synthetic and conventional motor oils. Thanks to this unique feature, synthetic blends generally work with a wide range of engines, regardless of how outdated they are. If you have an older car, you will get much better use out of this variant.

Castrol is undoubtedly the superior option when conventional motor oils are concerned, making it easy for them to dominate the world of synthetic oil blends. The two brands don’t have all that many differences in this category, so selecting could pretty much be a toss-up.

3. Conventional Oil

Over the years, conventional motor oil has lost significant popularity and is sold less to consumers now. Despite that, it’s an asset for older engines that operate solely on conventional motor oil. The primary reason this category of motor oil is still relevant is that some engines are only compatible with the conventional choice after reaching a specific age.

This oil features a blend of “pure” petroleum products and additives of the company’s choice. The budget-friendly choice in many cases, conventional oil isn’t usually the best for long-term lubrication.

Castrol Oil

Castrol oils have become a household name for their amazing, affordable products. Their oils have shown to be compatible with almost all kinds of vehicles, regardless of the condition. For most types of maintenance works and other general purposes, you can always get a Castrol product that seems to be just what you were looking for.

1. About The Company

Castrol is a leading brand in the field of high-performance engine oils for all sorts of automobiles. Initiated as a startup in London in the 19th century, the brand derives its name from “castor oil,” one of the main ingredients in their oils.

The top-notch quality and superior marketability of the products powered the company, helping it reach new heights. It now functions as a subsidiary of British Petroleum and appeals to the market with a wide variety of products, ranging from industrial products used for exploring space to consumer-grade engine oils the average driver could smoothly work with.

2. Castrol Edge At A Glance

Various brands are marketed under the name “Castrol” by the parent company. Their premium lineup is, you guessed it, the Castrol Edge. This line features some of their best-performing products, some of which are so good that they’re often used for race cars and supercars.

Castrol Edge motor oils have an obvious edge in this area since they are created from 100% synthetic blends designed specifically for high mileage and performance.

State-of-the-art Titanium technology in the oils makes them thrice more viscosity stability in comparison to other oils you can find.

Needless to say, most car manufacturers, as well as professional racing teams, often rely on Castrol Edge products. These oils are compatible with many luxury automotive brands too such as Audi, Jaguar, Land Rover, and Volkswagen. When you want a clean engine with great performance, you cannot go wrong with Castrol Edge.


  • Better protection against wear and tear
  • Contains titanium particles
  • Long-lasting, solid performance
  • Much more affordable
  • Suitable for the majority of American and European car models


  • Not always available in general physical outlets

Mobil 1

Mobil 1 has gained popularity as a higher-end product suitable for new, well-maintained vehicles. In all honesty, this makes up the lion’s share of the driving population, so people can’t nitpick with the generic, “This wouldn’t work for the ‘50s car I drive!” Well, unless they have one, of course.

And while it’s thought that Mobil oils are generally pricey between Castrol Edge vs. Mobil 1, they come at competitive prices. Plus, they are ideal for a long list of applications.

With that said, it’s rather disappointing that Mobil 1 doesn’t have any plans to manufacture products for older vehicles that typically need much more maintenance to stay in good condition.

1. About The Company

Mobil 1 came into being about a century ago and changed the oil industry radically. In no time at all, it jumped to the top of the charts. In fact, the company was much more popular back in the day. The downsizing isn’t that noticeable when you’re as big as Mobil.

Even though the company went through its fair share of ownership changes, thankfully, that hasn’t negatively affected the grade of their performance-based products. Not to mention how Mobil 1 has actively taken part in the research and development aspects of all synthetic engine oils.

Due to that, they don’t have to overdo it with the marketing as they know that the products they’re putting out, are actually good.

2. Mobil 1 At A Glance

The whole engine oil product line from Mobil is a no-brainer, each greater than the previous. But they really surpassed all expectations with the Mobil 1 lineup. Through the years, the company has constantly developed and marketed this premium engine oil line and been incredibly successful in it.

The premium brand name offers high-quality performance, particularly for high-performance engines alongside newer vehicle models. Mostly entirely synthetic engine oils, Mobil 1 oils are guaranteed to optimize your engine’s use, giving you an extended service life paired with newfound capabilities.

Interesting fact: Mobil 1’s diversity can be explained with one simple sentence. There’s even a choice for commercial and military aircraft. Aside from all the pluses, the obvious disadvantage is that it might not be the best pick for older automobiles.


  • Meets Dexos standards
  • All-round engine protection
  • Full synthetic blend
  • Powerful cleansing action
  • Good performance even in low temperatures


  • A bit costlier

Mobil 1 vs Castrol Edge: Best Motor Oil

Don’t trust anyone who says either one of the oils is better than the other “just because.” If you ask, who is the winner in Castrol Edge vs. Mobil 1, we ask “In which department?”

Generalizing isn’t going to give us the actual answer on which brand reigns superior and why. We have decided on a handful of metrics to base our comparisons on, and we make the decision from there.

What we mean are the most common marketing groups in the category of motor oils; the most mentioned features these products are advertised under. Like, some engine oils “offer” prolonged engine lifespan, some are marketed as the top solution for heavy-duty performance, and so on.

Let’s break down these niche markets individually and see which brand is the winner: Castrol Edge or Mobil 1.

Castrol Edge vs Mobil 1

Mobil 1 vs Castrol Edge: Comparison Table

You’ll find detailed explainers for each category down below. But for reference, here’s a TL;DR list of Mobil 1 vs Castrol Edge:

Mobil 1 vs Castrol Edge

Castrol Edge vs Mobil 1 #1: Cleansing Oils

Cleaning properties are an important feature in motor oils as this helps with the overall maintenance and working condition of your vehicle. No wonder most motor oils heavily market “stellar cleaning action.”

Now, the point to catch here is that most, if not all, engine oils feature cleaning capacity to a certain extent because they are naturally infused with dispersant additives and detergent.

The question to ask is how high the concentration of said additives in the oil is. You can turn a poorly maintained engine 180-degree around when you have the right engine oil that can conduct some thorough cleaning.

As we’ve mentioned multiple times before, Mobil’s primary focus isn’t products for older, out-of-shape vehicles with raggedy engines. Thus, Castrol Edge is better when discussing cleaning properties.

Castrol Edge vs Mobil 1 #2: Preservation Oils

As a rule of thumb, look into a motor oil that promises and delivers superior preservation properties. A product like that can maintain the condition and quality of your vehicle, prolonging its life so it can perform well even when pushed to the limits. It would be wrong to say this kind of oil makes the engine “better” but it does stop it from getting worse.

After some careful evaluation, we found that Mobil 1 would be the better pick in this sector. However, there is one exception – Castrol Edge is enriched with magnetic additives that come in really handy when working with older engines.

Castrol Edge vs Mobil 1 #3: Performance Oils

Designed and marketed specifically for high-performance vehicles, like professional race cars and tuner cars, performance oils improve the power of certain automobile engines.

There are quite a few subtypes in this department depending on what sort of car you own and its engine’s performance-heaviness. Nonetheless, the winner is clear in performance oils.

Mobil 1’s stunning lineup offers many high-performance products that would give you the best driving experience, whether it’s drifting, high-speed cruising, or whatnot. Castrol Edge oils weren’t made for this – it’s as simple as that.

Castrol Edge vs Mobil 1 #4: High Mileage Oils

The best of both worlds, high mileage oils offer equal helpings of preservation capabilities and cleaning properties. These keep the engine performing smoothly for long while protecting it from rust, corrosion, and other performance barriers.

The efficiency of these products depends heavily on the kinds and grades of additives incorporated to give the oil its viscosity.

In the department of motor oils that provide the highest mileage, the latter is the winner between Castrol Edge vs. Mobil 1. Almost all the products in this lineup are claimed to be high mileage, and they rarely fail. Castrol Edge puts up a mentionable fight in older engines.

Castrol Edge vs Mobil 1 #5: Diesel Engine Oils

Castrol Edge vs Mobil 1

Automotive 101: Engine oils are often manufactured to be used in a specific kind of engine and the type of fuel they run on. As there are oils made to work with gas, there are oils made to work with diesel.

However, motor oils these days are pretty versatile, engineered to work smoothly with both diesel and gasoline engines, particularly the ones featuring full synthetic blends. But if your car has seen its fair share of days and works on a diesel engine, it’s best to look into specially formulated motor oils.

We would suggest you ditch the Castrol Edge vs Mobil 1 debate altogether in that aspect as both of these brands have shifted toward producing all-purpose oils. If we just had to choose one, it would be Mobil 1 since the lineup includes performance diesel oil and diesel motor oil, especially for commercial vehicles.

Castrol Edge vs Mobil 1 #6: Heavy-Duty Oils

The name might give you the wrong idea – “Heavy Duty.” In reality, these motor oils aren’t made for consumer-grade transport. What this implies is that even if your car, motorcycle, SUV, or truck has experienced quite a lot, they still don’t need heavy-duty automotive oil.

It’s also essential to draw the line between heavy-duty oil and performance oil as the latter is designed for tuned engines.

Heavy-duty oil would be used for a variety of industrial equipment people may own like tractors or other kinds of agricultural equipment. Between either company, the Mobil Delvac motor oil is the only heavy-duty oil sold in the market.

Castrol Edge vs Mobil 1 #7: Viscosity Types

Many others might skip this point altogether but it’s worth mentioning. The two companies actually have some differences when it comes to the oil’s viscosity. In fairness, this can partially be accounted to the particular brands, niches, and types, but we can’t say that all the different instances are due to obvious reasons.

The viscosity difference gives both companies a unique image, with their general “theme” shining through.

A good example would be the number of options Castrol offers for cold weather in contrast to Mobil. It is also noteworthy that Castrol produces a wider range of hot-weather motor oils as well. In general, Mobil oils have a narrower range in the department.

The 1st Number

The first number stands for the viscosity of the automotive oil at freezing temperatures. As the number gradually increases so does the oil’s performance and capability to remain smooth, even if the temperature dips below freezing point (for more insight into how this works, check out our guide on does oil freeze).

Keep in mind that adding pour-point depressant to oil increases performance when the weather conditions are too chilly.

Coming back to Castrol Edge vs Mobil 1, a natural freezing viscosity rating (20) has given Castrol the upper edge over Mobil here. But, 20wXX motor oil can’t exactly be deemed a necessity even if you reside in the northern region of the nation.

The 2nd Number

The exact opposite of the first number, the second number tells you what to expect of the oil when the engine heats up. Similar to the first number, a higher second number translates to better performance and viscosity in elevated temperatures. However, the risk here is the oil becoming too thin in contrast to too thick.

As mentioned before, Castrol has a wide variety of oils in different viscosities perfect for hot temperatures. On the other hand, Mobil has come out with this new (and amazing) Japanese-style 0w16 motor oil. It’s great for fuel economy but is enriched with certain additives which give it the signature thinness.

Castrol Edge vs Mobil 1 #8: Key Technologies

In all comparisons, there is that one feature that distinguishes a premium product from a mediocre one. This applies to both Mobil 1 and Castrol Edge. Both oils feature the use of state-of-the-art technologies to establish a competitive advantage in the market.

For Castrol Edge, the incorporation of Titanium technologies in its products acts as the main selling point, contributing to its worldwide popularity. The technology guarantees incredible engine performance. This happens by the change in the oil’s traits under pressure.

Mobil 1, on the other hand, doesn’t seem to have a big technological change associated with the name aside from full-synthetic performance. Don’t count Mobil 1 out just yet – the oils are engineered to offer stunning performance even in the worst of terrains and climates.

Summary: both feature impressive technologies.

Castrol Edge vs Mobil 1 #9: Best For What Vehicles

Both Castrol Edge and Mobil 1 are general-purpose automotive oils suitable for almost any model of vehicle. Nonetheless, each stands on its own under different kinds of vehicles and unique situations.

For instance, Mobil 1 is a great match for most modern-day vehicles, including SUVs and trucks. The oil formulation makes it an ideal fit for driving on rough, cold terrain.

Castrol Edge is a good fit for high-performance cars. Thus, you’ll see it being a top choice for racing cars. The titanium technology reinforces the engine against breakdown.

Mobil 1 is definitely the winner here.

Castrol Edge vs Mobil 1 #10: Price

Premium-quality products are generally priced high, at least too expensive for the everyday motorist. Fortunately, both these oils come at budget-friendly tags. Typically, you will have to pay less than $30 for a 5-quart container for both brands.

That being said, Castrol Edge comes cheaper between the two. In number, it’s almost $10 less than its competition. But this is subject to change on the location of purchase. Either way, you’re going to get great value out of both. If you’re absolutely penny-pinching and need a clear name, we’d say Castrol.

Castrol Edge vs Mobil 1 #11: NOACK Volatility Test (ASTM D-5800)

First, let’s talk about the NOACK Volatility Test, a vital metric to gauge oil’s ability to withstand evaporation in high-temperature conditions. According to API SN/SN Plus and ILSAC GF-5 standards, the evaporation loss threshold stands at 15%.

However, this percentage lowers to 13% according to Europe’s ACEA specifications and General Motors. When put to the test, Mobil 1 Full Synthetic lost 8.1% and Castrol Edge Full Synthetic lost 8.8% of their original weights at 245.2º C in an hour.

The data shows that Mobil 1 offers slightly superior resistance to boiling off under extremely high temperatures. Keep in mind, this is specific to the full synthetic variant and does not represent other oil types.

Castrol Edge vs Mobil 1 #12: Viscosity Index and Cold Crank Simulator Test (ASTM D-5293)

Despite being multigrade SAE 5W-20 oils, viscosity tests help expose differences in oil behaviors during cold startups and operating temperatures. An oil with a higher viscosity index (VI) maintains a more stable lubricating film over a broader temperature range, advantageous in fluctuating weather conditions.

Examining the data, Castrol Edge Full Synthetic has a slightly higher VI of 160, compared to Mobil 1’s 154. The Cold Crank Viscosity at -30º C also leans in favor of Castrol with 3,701, compared to Mobil 1’s 3,940. Thus, Castrol Edge offers slightly better viscosity performance under extreme conditions.

Castrol Edge vs Mobil 1 #13: Total Base Number (ASTM D-2896)

TBN or Total Base Number is an indicator of a motor oil’s ability to neutralize acids, control sludge formation, and handle contaminants over extended periods. Mobil 1 has a TBN of 9.0, slightly higher than Castrol Edge’s 8.6, offering a minor advantage in prolonged protection against corrosive effects.

Yet, Castrol Edge shows more compatibility with GDI engines due to its lower calcium content, reducing LSPI frequency.

Castrol Edge vs Mobil 1 #14: Multielement Determination (ASTM D-5185)

Utilizing ICP-AES technology, this test measures additive elements, contaminants, and wear metals in both used and unused lubricants. While typically present at negligible levels in new oil, quantities exceeding 10 ppm can indicate contamination.

Regarding Antiwear (AW) additives, Castrol Edge Full Synthetic has slightly higher levels of phosphorus, zinc, and boron, offering a minor advantage in protecting high-friction engine components. Conversely, Mobil 1 has slightly fewer contaminants, suggesting a marginally lower risk of premature engine damage.

Castrol Edge vs Mobil 1 #15: Lab Testing & End-User Considerations

At the end of the day, motor oil isn’t just about lab numbers. It’s about longevity, performance, and protection. Both Mobil 1 and Castrol Edge deliver on these fronts, as seen in countless reviews by satisfied customers and long-term users.

However, your vehicle’s make, model, and age, as well as your driving habits and environment, can make a difference in which oil will serve you best. Consider these factors alongside our lab test comparisons for the most informed decision.

To conclude, both Mobil 1 and Castrol Edge have unique strengths, and selecting between them should take into account all the factors we’ve discussed, alongside specific vehicle requirements and operating conditions.

Always refer to your vehicle’s manual or a qualified mechanic for the best advice on choosing the right motor oil.

How To Change Your Engine Oil

While we’re looking at Mobil 1 vs Castrol Edge, once you’ve found the right oil for you, you might be interested in learning how to change the oil yourself:

An oil change is a cornerstone of DIY car maintenance. It’s a simple process requiring minimal tools, providing an excellent opportunity to save money and connect with your vehicle. Spending time under the hood allows you to spot if anything else requires attention, turning maintenance into a proactive endeavor rather than a reactive one.

DIY oil changes can save you between $25 to $75, compared to professional services. As for the time required, your first oil change may take up to an hour, but with practice, you can reduce this to about 30 minutes.

For a successful oil change, you’ll need the following tools and materials:

  • Wrench to remove the drain plug (box end or socket)
  • Oil filter wrench
  • Oil drain pan
  • Funnel
  • Latex gloves
  • Jack and jack stands or ramps (optional, depends on ground clearance)
  • Oil
  • Oil filter
  • Replacement drain plug washer (depending on application)

Step 1: Determining the Oil Type and Quantity

Before you buy your supplies, consult your car’s owner’s manual to verify the type and quantity of oil needed. It’s essential to match the oil’s viscosity to your engine to ensure optimal performance. Some engines require synthetic oil, while others don’t.

Step 2: Gathering Your Tools and Supplies

In addition to oil, prepare your oil filter, wrenches, and other supplies. Depending on your vehicle, you may need to elevate it to gain access to the drain plug and filter. For such cases, never rely on the car’s flimsy jack – use a solid floor jack and safety stands instead.

Step 3: Preparing Your Vehicle

Ensure your engine and oil are warm, not hot, before you start. If you need to raise the car for better access, ensure you install safety stands. If your vehicle has an undercover protecting the engine, remove it if necessary to access the oil filter and drain plug.

Step 4: Locating the Oil Filter and Drain Plug

Once your vehicle is ready, locate the oil filter and drain plug. Most cars have a bottom-mount screw-on filter. If the plug and filter are far apart, complete the draining and replugging process before working on the filter.

Step 5: Draining the Oil

Place your drain pan under the drain plug, slightly offset to account for the oil’s outflow angle. Remove the oil filler cap to allow oil to flow out more smoothly and quickly.

Step 6: Unplugging and Draining

Put on your gloves to avoid oil spills on your hands. Remove the drain plug with a common end wrench. Remember, oil comes out warm and quickly, so avoid placing your hands in the oil’s path.

Step 7: Replugging

After draining all the oil, replace and tighten the drain plug using your wrench. Be careful not to over-tighten the plug, as it could damage the oil pan’s threads.

Step 8: Changing the Oil Filter

With the oil drained and the drain plug secure, it’s time to change the oil filter. Use your oil filter wrench to unscrew the old filter. Once removed, lubricate the rubber gasket on the top of the new filter with the new oil. Screw the new filter in place as tightly as possible by hand.

Step 9: Adding New Oil

Now, with a new filter in place and the drain plug secure, you’re ready to add new oil. Position your funnel at the oil filler hole and slowly pour in the new oil. Take care not to exceed the quantity mentioned in the owner’s manual.

Step 10: Checking Oil Levels

After adding the oil, withdraw the dipstick, wipe it clean, reinsert it, then pull it out again to check the oil level. The oil should be within the “full” mark on the dipstick. If it’s low, slowly add more oil and check the level again. Be careful not to overfill, as too much oil can damage your engine.

Step 11: Final Checks

With the oil level satisfactory, replace the oil filler cap and run the engine for a minute or so. Check for leaks from the drain plug and oil filter. If all is well, turn off the engine and do a final oil level check. Sometimes the level drops slightly after the oil circulates in the engine. Add more oil if necessary.

Step 12: Cleaning Up

Once everything is in place and the oil level is satisfactory, it’s time to clean up. Take off your gloves and dispose of them properly. The used oil filter and drain plug washer can be recycled at many auto parts stores.

Store the used oil in a sealed container and bring it to a recycling center or a store that accepts used motor oil. Remember, it’s essential to dispose of used motor oil responsibly; never pour it down a drain or on the ground.

Step 13: Closing Notes

Changing your car’s engine oil might seem intimidating at first, but with a little practice, it becomes a manageable and satisfying task. By regularly changing your vehicle’s oil, you can save money, become more familiar with your car’s needs, and extend the life of your vehicle.

Remember that while the process outlined in this guide is generic, always refer to your vehicle’s owner’s manual for specific instructions. Certain vehicles may have unique requirements or steps that should be followed.

As you become more comfortable with the process, you’ll gain confidence and pride in maintaining your vehicle’s health. After all, a well-maintained vehicle runs better, lasts longer, and brings you peace of mind.

Castrol Edge vs Mobil 1 & Motor Oil Types and Comparison: Facts

Engine oil is vital to vehicles, preventing engine wear and cooling it under pressure. Modern versions improve performance with additional components. Different institutions, including the American Petroleum Institute, test and refine motor oils.
