Best 0w 20 synthetic oil


For maximum engine performance and protection, synthetic oils are without a doubt your go-to. However, taking extreme weather conditions into account, you need oils that will rise to the occasion and 0w-20 synthetic oils have done just that.

Lubrication is the reason why you are able to cover several miles without any hustle; it’s the heart of the engine. Take this out and your car will barely make it for an hour on the road.

Picking the right type of engine oil is therefore important. With so many brands out in the market, we have chosen to narrow it down to the most recommended oil by automotive manufacturers. That is the 0w-20.

We will look at the best 0w-20 synthetic oils you need to be on the look-out for. But, before we do that let’s have a brief introduction as well as a comparison table.

Best 0w 20 synthetic oil

There are so many brands out there that can make the process of finding the right oil brand for your engine, can be pain tasking. There are different factors to consider such as weather conditions, wear and tear and not to mention the different codes on these products.

The 0w-20 code among others, can be a bit confusing to understand but basically this code denotes the oil viscosity classification by the Society of Automotive Engineering i.e. SAE.

The ‘w’ in the code denotes winter certification. It is therefore the ability of the oil to flow at really low temperatures i.e. 0°F. The 20 on the other hand, shows the viscosity of the oil at high temperatures. Lower numbers indicate that the oils viscosity is great under extreme temperatures.

Now that we have the code figured out, let’s get into some of the best 0w-20 synthetic oils currently in our markets.

Here’s a buyer’s guide to help you narrow down your decision to a specific motor oil:

Buyers Guide for the Best 0w 20 synthetic oil

Look at the recommended oil for your car

Every car comes with its own oil specifications and it’s therefore crucial that you select the right one. Whether or not you’re driving on gas or ethanol blends, you will have to read your user’s manual to see what’s recommended.

Using oil that isn’t specified for your car can be catastrophic to say the lease. It could damage your engine, eventually killing it. This is because the oil comes in different formula combinations that have been engineered to cater to certain engines. Mix this with a wrong engine and all possibly horrible things, will happen.

Oil Type

The types of oils in the market can be a bit overwhelming but here are some of the classifications:

Conventional oil

These are oils found in most of the cars on the roads today. They are oils which haven’t gone through a thorough distilling process.

Synthetic blend oil

Synthetic blends are a combination of synthetic and conventional oils and is mostly used in heavy duty vehicles for protection

Full synthetic oil

Full synthetic oils offer better performance and benefits than conventional oils. They also have the heist protection and they are more durable.

Full Synthetic oil is as the name suggests; it is usually pure with additives that are free from any petroleum products. Some oils like the Mag 1 Full Synthetic Motor Oil are 100% synthetic.

High mileage oil

These oils are formulated to offer extended protection and can have mileage of close to 75,000 miles before one goes in for a change.

Understanding viscosity codes

Understanding viscosity levels will be of you use to you due to the different seasons experienced annually. Our focus on this article has been on the 0w-20 synthetic oil. The codes basically indicate the oils ability to withstand really high temperatures as well as really low ones. And this ability is achieved by the viscosity levels.

We had explained earlier what the W stands for i.e. winter; and so the number before denotes the oil’s viscosity at 0°F. The numbers after denote the oil’s viscosity at 100°C.

In more understandable terms, when you have a lower first number, this is an indication that that particular oil thickens less in cold temperatures than oils with a higher first number. For example, 0w-20 oils with thicken less in cold temperatures than 10w-30 oils.

Similarly, when you have a lower second number, this shows that the oil will thin out faster during high temperatures than oils with a higher second number. For example, a 5w-30 oil will thin out faster than the 5w-40 oil during high temperatures.

Viscosity on the other hand is the level of degree that oil has to be able to resist thinning. Thinning of the oil is caused by high temperatures while thickening of the oil is caused by lower temperatures. Good oil should have great withstanding power of the varying weather conditions and should be able to run for many miles without breaking.

Additives are a great way of stabilizing the oil so that it reduces the fluctuations.


Additives are added in the oils to maximize on the benefits of the oil. These additives vary depending on the function they will be bringing to the oil. We have anti-wear additives which protect the engine against wear, additives responsible for the improvement of viscosity, antioxidants to prevent oxidation during cold weathers, foam inhibitors that keep the oil from foaming, among others.

Detergents are also added to the oils and their main purpose is to keep the engine clean by getting rid of any soot or engine deposits.

Oil labelling

Don’t just buy any oil that you found on the market. Make sure you look out for certifications before you purchase rat kill for your engine. Certified motor oil will have a donut on the right side which is an indication of API and SAE viscosity rating.

Another label you’re probably to find is the starburst symbol which is an indicator that the oil has passed SL test services.


We went around looked at what many people are asking with relation to the synthetic oils and we came up with a few Q’s and A’s to try and get you the answers.

Is 0w-20 always synthetic?

No, not always as some of them are a combination of synthetic and conventional oil.

Can I use 0w-20 oil instead of 5w-20?

First things first, check your recommended viscosity rating and stick to that as we do not recommend switching to something else.

Lastly, while these two ratings may seem similar there is a difference when it comes to thinning and the 0w-20 is a bit thinner than the 5w and it therefore does less damage on your engine.

This is the case in lower temperatures. While neither of the two are exceptional when it comes to proper oil flow during winters, the 0w is slightly better. If you’re currently using the 0w-20, then we don’t see the point in switching.

How often do I need an oil change when using synthetic oil?

There is no definite answer to this as it varies from car to car as it is dependent on your driving. For instance, if you use your car for light errands such as going to the mall, you will require fewer oil changes than if you were hauling heavy loads from one state to another.

However, there’s a general rule in the auto world to check your oil after every 3,000 to 5,000 miles but get in the habit of always checking your oil every month just to be on the safe side.

Some manufacturers have specific recommendations in their user manual. For example, Toyota have some cars whose oil change recommendation has been approved for every oil changes every 10,000 miles when using the 0w-20 synthetic oil.

Is synthetic oil better for high mileage cars?

Yes, it is and the reasons for our answer are discussed in this article. With cars that have a lot of miles on them, synthetic oils are ideal because they offer more engine protection against wear and friction. The closer you are to 100,000 miles, the more you should consider making the shift to synthetic oils. Synthetic oils will enable your engine to withstand severe conditions under whichever extreme conditions you’re faced with.


As we wrap up, we hope that this article has helped you narrow down which of the best 0w-20 synthetic oils discussed above, you need for your engine.
