0W-20 Oil Buying Guide

Looking for the best 0W-20 oil but don’t know where to start? I get you. After all, there are virtually unlimited options out there, and while all of them seem great, not all may be suitable for your vehicle.

So, in order to help you out, here are the most important factors that you need to take into account when determining which 0W-20 synthetic works best for you and your car.

The purpose of 0W-20 synthetic oil

First things first. Let’s talk about exactly why you need an 0W-20 oil for your vehicle, and what it can do for you. While there are many different types of engine oils out there, a full synthetic oil such as an 0W-20 oil offers the best features and performance for your vehicle.

It not only lubricates your engine, but also cleans it up and keeps deposits at bay, all while reducing friction, preventing wear and deterioration, improving engine performance, enabling smooth shifting, and enhancing your fuel economy.

These are all important things that no other type of engine oil can achieve at the same level.

Synthetic blend vs full synthetic

In line with what I’ve just discussed, one of the first things you need to decide on is whether you’re fine with a synthetic blend of 0W-20 oil, or you really want to get the maximum performance that a full synthetic oil can offer.

This is because synthetic blends are considerably more affordable, and are thus perfect for those on a budget. They still work great in terms of engine protection and performance, just not as superior as full synthetic options.

That said, a full synthetic engine oil will save you even more on fuel costs, protect your engine for longer so you don’t have to worry about engine repairs in the foreseeable future, and give you a much better overall engine performance.


Another thing that makes full synthetic oils stand out from synthetic blends is that they offer a significantly higher mileage, at least twice as long as that of synthetic blends, so you can run your car for longer before needing an oil change.

To give you an idea, synthetic blends will give you a mileage of about 7,500 miles, while full synthetic oils have an oil change interval of 15,000 miles.

Other oil types

Now, if you’re really trying to save up on upfront costs, you can always consider other types of engine oil. These are much cheaper than both full synthetic and synthetic oils, although you cannot expect the same level of performance.

There are conventional crude oils that are relatively sustainable and have decent lubricating properties, and are most suitable for new cars with new engines that don’t need that much protection just yet.

You’ve also got high mileage oils that are specially formulated to try and keep your engine for as long as possible after it’s hit the 75,000 mile mark. It has the capacity to prevent oil leaks and minimize oil burn off, as well as eliminate wear and friction.

Other important considerations before buying the best 0w-20 oil

Other important considerations before buying the best 0w-20 oilAside from the ones I’ve already mentioned, there are several other important considerations that you need to factor in when purchasing an engine oil for your vehicle.

Manufacturer’s specification

This is perhaps the most important thing you need to remember. Different cars have different engines and require different types of engine oils. Using the wrong one can result in not being able to start your car, and severely damage your engine.

As such, it’s important to base your decision on which oil to buy on the manufacturer’s specification. This is based on the specific requirements of your engine, including what type of fuel it runs on.

Therefore, make sure to check whether the product you’re looking to buy is compatible with your car’s make and model, and suits your specific engine requirements, which might vary as well depending on how much mileage it has.

Oil compatibility

Now, another thing you need to take into account is that your car already has engine oil in it, and as such, the oil you will be buying needs to be compatible with this existing oil as well, so that the engine runs smoothly and won’t cause you any problems.

For example, there are many synthetic oils that work with similar synthetic oils, and 0W-20 synthetic oils are designed to be compatible with conventional oils. Of course, there are also advanced formulated oils that can work on any type of engine oil.

Lubrication capabilities

One of the primary functions of engine oil is to lubricate the moving parts and components of your engine, and in this aspect, it’s only natural that the oil’s lubricating capabilities be one of the main things you take into account.

Not all engine oils work the same in lubricating your engine and minimizing friction, and this depends on how the oil is formulated. You need to find a synthetic oil that has the perfect formulation for your engine’s specific requirements.

Sealing properties

Another important factor to consider is how much sealing properties the oil offers when it comes to protecting your engine from sludge and other harmful particles and deposits that can cause damage to the engine.

Remember, a clean and fully protected engine will run smoother and better overall than one that is filled with grimy deposits that build upon the engine’s parts and cause issues on how it performs.

Corrosion and rust resistance

Also in terms of protection and helping your engine last longer, the engine oil should have excellent capabilities in preventing rust and corrosion, both of which can seriously damage your engine and make it fall apart.

Premature wearing and engine damage will reduce your car’s mileage and cause a multitude of damage that can easily be prevented and can leave you with a hefty bill in repair costs, especially if you have to change the entire engine.

Temperature resistance

The beauty of synthetic oils such as 0W-20 oils is that they ensure that your engine performs well no matter what the weather conditions, such as when it’s especially hot or cold. So if you want the best and most reliable engine performance, get an oil that has excellent temperature resistance.

This means that the oil maintains its viscosity and doesn’t thin out or thicken depending on the temperature. A stable viscosity means that the lubrication and protection properties of the oil remain the same, so your engine runs smoothly all throughout.


No engine runs without its engine oil, and this is why choosing the right kind of oil for your car is so important. It’s what enables your engine to run and keeps it running at peak performance for a significant amount of time.

Knowing the right things to consider will let you find the best 0W-20 oil for your car, and will give you the kind of performance, protection, and fuel economy that you want. And remember, there are different types of oils for different engines.

That said, my best recommendation for you is the Castrol EDGE 0W-20 Advanced Full Synthetic Motor Oil, especially since it makes use of an advanced formulation that makes it compatible with almost all types of engines.

It also offers superior protection against friction, wearing, rust, corrosion, sludge, and other deposits, and ensures that your engine is at its peak performance with a high mileage and an improved fuel economy.
