When talking about motor oil, the best in the industry are true synthetics.Unlike traditional dino oil, these products are much better at handling temperature extremes and maintaining a high level of viscosity throughout the life of your engine.

What’s more, they help minimize fuel consumption, ensuring you can drive with more fuel efficiency.To ensure that your oil is purely synthetic, it has to be of the base group IV or V, as any other base stock isn’t a pure synthetic but rather a synthetic blend.

The 0w20 is one of the most common SAEs and we’ve got ton of requests about what the best options are. Here are our top 5 picks.

What You Need To Know About 0W-20 Synthetic Oil

1. What is 0W-20 oil?

There was a time when motor oils only had a single viscosity. While they can get the job done, it also makes them quite vulnerable to changes in temperature.

0W-20 oils seek to address this issue with their dual viscosity. It makes your motor oil efficient even in extreme temperatures, which is exactly what the label refers to.

“0” stands for zero as the lowest viscosity grade in really cold weather; the W means it’s a weight formulated for winter.

Meanwhile, the “20” stands for its viscosity during hot temperatures. The higher this number is, the more viscous you can expect your motor oil to be in the heat.

2. Are 0W-20 synthetic oils?

Yes, they are. 0W-20 oils usually come in two formulations: fully synthetic or synthetic blend. 

They are formulated this way to make them function even in different temperature conditions.

They do this by molecularly breaking down mineral oil and restructuring it to achieve the needed formula.

Fully synthetic oils are typically labeled “Premium” or “Advanced.” Interestingly, it doesn’t really refer to the oil grade; it only seeks to promote the brand’s quality.

3. What are 0W-20 oils used for?

There are several reasons car owners, particularly those who drive modern petrol and gasoline engines, use 0W-20 oils.

It promotes amazing lubrication.

Lubrication is the main function of motor oils.

There are a lot of moving parts inside your car’s engine, and these can create a lot of friction that can ultimately lead to engine damage.

Motor oil is applied to give it that much-needed lubrication and protection from friction.

It boosts engine performance.

Aside from ensuring your engine runs smoothly with adequate lubrication, 0W-20 oils prevent engine wear and the accumulation of engine deposits.

It helps promote fuel efficiency.

In terms of fuel efficiency, you will be pleased to learn that 0W-20 oils promote fuel economy, especially for older engines.

It prevents corrosion.

The use of 0W-20 oil is known to provide oxidation resistance, so it can decrease your worries about corrosion and related issues.

Is 0W-20 Oil the Best Choice for My Car?

Honestly, the answer depends on several factors.

What makes 0W-20 so popular is the viscosity grade it can guarantee regardless of the current temperature. The reasons we have stated earlier are also great benefits to consider.

That said, we still don’t recommend it for all types of vehicles.

For instance, two-wheelers and aviation vehicles need formulas that can operate amidst extreme heat.

While the main objective of the 0W-20 is to provide a balanced formula that can work both ways, we cannot deny that it works better in the cold than in the heat.

When choosing the right formula, start by figuring out the right viscosity grade for your particular vehicle.

You can do this by referring to your car’s manual. Alternatively, you can ask your mechanic to get more information and valuable insight.

We hope that our quick rundown of the best 0W-20 oils today helps you make a more informed purchase decision.

Good luck!
