The Best 0w 20 Synthetic Oil – The Top 8 Reviewed

When it comes to choosing the right motor oil there are a lot of options out there.

To help you out we’ve have narrowed your search down to eight of the best synthetic motor oils in this category.

Let’s kick things off with our top pick.

1. Castrol GTX MAGNATEC

Rating: (4.8 / 5)

0w-20 synthetic oil castrol gtx magnatecCastrol GTX MAGNATEC takes our number one spot thanks to some incredible features.

It helps critical engine parts run up to four times smoother, and has been proven by industry experts to offer superior wear protection to its rivals.

It’s especially effective against viscosity breakdown, ensuring that there’s no sludge build up.

The real magic occurs on start up.

According to tests, up to 75% of engine wear occurs during the first few minutes of warm up.

When you turn off your engine, oil drains from the critical parts.  That’s not the case with this stuff.

Instead the “intelligent” molecules in this motor oil form an added layer of protection during warm up when your engine needs it most.

The result is that engine wear reduces dramatically, and with it the chance of damage and repairs.

With GTX MAGNATEC you’ll have a smoother running engine, and you’ll enjoy better fuel economy than with its competitors, which is a nice touch.

It’s also, surprisingly, no more expensive than any of the others on our list.  What’s not to like?

So, What’s The Best 0w 20 Synthetic Oil?

The bottom line is that there are a lot of motor oils  to choose from, but all of those listed here are going to improve your engine performance, reduce your emissions, make your vehicle last longer and make it run better than it has before.

If you pushed us to choose one, we’d have to go with Castrol GTX MAGNATEC.  We love the transparency of the manufacturer explaining how it’s product works (rather than using generic jargon like many others).

castrol gtx magnatecIt’s well priced, performs well in extreme temperatures, is suitable for so many vehicles, and is consistently praised on review by independent users.

Mobil 1 Advanced comes in a very close second and if you prefer that brand there’s no reason not to go with it.

For value for money AmazonBasics is very hard to beat.  And for turbo and supercharged performance engines you should give Valvoline SynPower some serious consideration.

Synthetic Oil Vs Regular Oil

scaleSo, we’ve looked at some of the leading brands, now let’s consider why you should choose a synthetic oil over a regular, conventional oil, for your vehicle.

The answer, in short, is that you’ll experience greater levels of protection for the key components of your engine with a synthetic oil, and with that comes superior performance.

But that’s a fairly blanket statement that we feel needs a bit of explaining so we can understand exactly how synthetic oil is made.

Like conventional motor oil, synthetic oil is made from crude oil mined from the earth.  After extraction, it undergoes the normal refining process of regular motor oil.

The difference is that it is then put through an intensive purification process that involves distilling the oil to separate it into its basic components.

The process removes contaminants and impurities from the oil, leaving behind a purer substance whose individual molecules are better equipped to protect your engine.

Why Use Synthetic Oil

There are lots of reasons why synthetic oil is better than regular, but the most important four are set out below:

1. They Provide Greater Protection Against Wear And Tear

When it’s working, an engine’s parts move at great speeds.  They come into contact with one another constantly, and therefore need a layer of protection, in the form of your motor oil, to prevent wear and tear.

Given the stress that is placed upon your engine, the conditions in there can get quiet extreme.  This means that over time, your engine oil will break down.

A traditional engine oil will break down a lot faster than a synthetic blend.  With the breaking down process your oil loses its ability to properly lubricate and protect your engine.

Synthetics are a lot more resilient.  This means that you get premium protection for longer periods between changes.  the result is less wear and tear, less damage, and therefore less repair costs.

2. Sludge Resistance

There are plenty of impurities for your oil to pick up as it makes its way around your engine.  A traditional motor oil will pick up all type of debris as it circulates, eventually turning to sludge.

Sludgy oil is not a good thing!  It loses its lubricating, protective characteristics, meaning that your engine will be exposed to more wear and tear.

A synthetic oil on the other hand has less of its own impurities, which makes it more resistant to deposits within your engine.  This ability to maintain lubrication for longer periods significantly reduces the likelihood of damage, extending the life of your engine.

3. Cold Weather Start Up

snow roadWhen you shut your car off for the night, the oil in your engine comes to a rest.  When you start it again the next morning the oil flows through, as it’s designed to, to lubricate and protect your parts.

Regardless of the temperature a traditional oil takes longer to change from its resting state to full flow, so your engine is exposed to friction for that bit longer.

In particularly cold weather the time that it takes to get into this flowing state can be even slower, compounding the damage.

The same is not true of synthetic motor oil.  The distillation process helps to create a more fluid oil that is adept at getting into this vital flowing state much quicker, meaning that your engine and its parts are protected as soon as you turn on the ignition.

4. Hot Weather Break Down And Evaporation

sun roadConversely, if you’re driving in extreme heat the oil in your engine is put under greater stress than in moderate temperatures.

The first consequence of this is that break down happens much faster, bringing forward the onset of friction damage.

The second consequence is that your oil can begin to evaporate at these higher temperatures, leaving your engine exposed with less lubrication.

In the heat this is par for the course for a conventional motor oil, but not so for synthetics, which are specifically designed to resist heat and endure, even when the thermometer is off the chart.

You can quickly see why, when it comes to synthetic oil vs conventional oils, the former is a strong favourite!

How To Choose Oil For Your Car – A Quick Guide

motor oilChoosing the correct oil to lubricate your engine can be a bit daunting to begin with.  There are lots of letters and numbers to understand before you begin to look at different brands.

Here’s a few handy tips to help you out:

1. Check Your Owner’s Manual

You can save yourself a lot of time and effort by referring to your owner’s manual to see what type and grade of oil the manufacturer recommends.

2. Understand The Viscosity Grading System

In this article we’ve been looking at 0w-20 synthetic oil, but what do the numbers actually mean?

Well, they refer to the viscosity level of the oil at extreme cold and extreme hot temperatures.

The first number (before the “W”) refers to the oil’s viscosity level at 0 degrees Fahrenheit, whereas the second number (after the “W) refers to the oil’s viscosity level at 100 degrees Celcius.

Yes, both temperature scales are used, that’s not a mistake.

A low first number indicates that a particular oil thickens less in the cold than an oil with a higher first number (ow-20 thickens less in the cold than 10w-30 for example).

A low second number indicates that a particular oil thins out quicker in the heat than an oil with a higher second number (5w-30 thins out quicker in the heat than 5w-40 for example).

3. Applying It To Your Driving Conditions

Once you understand the viscosity grading system you’ll be in a better position to pick a motor oil to suit your driving conditions.

The lower viscosity level of your oil in the cold, the easier it is to pump around your engine.

So if you regularly drive in cold weather you’ll need a motor oil with a low first grading number to ensure easy start us and quick lubrication in the cold.

The higher the viscosity level of your oil in the heat, the more viscous it will remain at higher temperature.

So if you regularly drive in extreme heat you’ll need a motor oil with a high second grading number.

4. Types Available

There are several types of motor oil available, but if you’re looking to change yours there are few reasons not to go for a synthetic.

For completeness there are:

  • Conventional motor oils which have not gone through such a rigorous distilling process;
  • Synthetic blend oils, which are mix of conventional and synthetic oils; and
  • Full synthetic motor oils, like the ones on this list offering maximum protection.

5. High Mileage And Age

If you have an old vehicle that has more than (or is approaching) 75,000 miles on the clock, you might consider changing to a “high mileage oil” that is specially formulated to extend the running life of high mileage engines.

We’ve written a full post on the best high mileage oils here.

FAQs

faqThere are plenty of questions that crop up when choosing a motor oil, ow-20 or otherwise, so we’ve set out below answers to some of the most common ones:

Q – Is Synthetic Oil Better For High Mileage Cars?

A – We’d say yes, for all of the reasons discussed above, and especially for cars with lots of miles on the clock.

Typically you’ll see brands advertising high mileage oils for cars with 75,000 miles on the clock or more.  It’s not imperative that you change at that point, but the closer you get to 100,000 the more you should be thinking about switching to a synthetic product for the superior level of protection that it will provide to your engine parts, particularly in extreme hot or cold temperatures.

Q – How Often Should I Change Synthetic Oil?

A – This really varies from vehicle to vehicle having regard to the type of use (and therefore stress) that your car is being used for.  As a rule of thumb every 3,000 to 5,000 miles is a good yard stick.

The best place to look is your car’s user manual.  Some manufacturers make certain recommendations – Toyota for example have some models where 0w-20 synthetic oil is required and they have been approved for extended oil changes of every 10,000 miles.

Circumstances are always different, so if in doubt on how long between synthetic oil changes, err on the side of caution.

Q – Is 0w 20 Oil Always Synthetic?

A – No, not always – as set out above a synthetic oil could in theory be blended with a conventional oil – for more information check out this discussion on BobIsTheOilGuy.
