Best 0W-20 Oil for Your Vehicle: Top 7 for 2021

The heart of any motor vehicle is the engine. This vital component needs regular maintenance and care to run correctly. The best 0W-20 oil can help you achieve optimal performance and protect the engine from unnecessary wear.

In the world of motor oils, it’s difficult to determine when 0W-20 should be used. This motor oil is ideal for cold climates when the viscosity can change the performance. Many vehicles rely on 0W-20 motor oil, which is almost always synthetic, to provide better efficiency and protection.

To find the right 0W20 oil for your application, you have a lot of choices to pick from. Our motor oil review helps you pick the best lubrication for your vehicle type and needs.

What is 0W-20 Oil?

Oil is rated by how it performs in cold or hot temperatures. The rating of motor oil indicates how stable it is at a certain temperature.

0W-20 motor oil is a viscosity that is suitable in both cold and hot temperatures. The W stands for winter viscosity, while the 20 refers to the oil viscosity at higher temperatures.

With the best 0W20 oil, your vehicle can handle the lower temperatures just as effectively as the hot climates. Most publications agree that this oil is made to be used between -52.6 and 401 degrees Fahrenheit, ensuring you are never driving in a situation outside what this oil can handle. It’s just one reason that many people use 0W-20 oil during the winter months.

Benefits of the Best 0W 20 Oil

It’s often more expensive to use 0W 20 oil, especially when it is synthetic. However, there are several benefits to consider about this upgrade.

First, if you are using synthetic motor oil, you will have to perform oil changes less frequently. This longer interval ensures you save more money over the long haul.

• Additionally, you can expect these benefits from synthetic 0W-20 motor oil.
• Maximum protection against breakdown and engine wear
• Ultra-low viscosity improves power and fuel economy, with less friction
• Better low- and high-temperature engine wear protection
• Improves cold starts, which is when wear often takes place
• Reduces sludge in older engines

However, you have to decide if the additional cost is worth it for you. If you are driving a vehicle that is on its last leg, you might not want to put more money into the oil upgrade. Instead, you might prefer using a cheaper conventional oil and getting the most out of the engine while you can.

Types of 0W-20 Motor Oil

As you look for the best 0W-20 motor oil, you have several types to choose from. For the most part, 0W-20 oils are usually synthetic, but you can find other options.

Full Synthetic 0W-20 Oil

Fully synthetic oils are best for vehicles that require high performance levels and maximum lubrication. With the higher viscosity level, the engine receives more protection from thermal breakdown and oxidation. Plus, this motor oil will break down oil sludge.

Overall, you can expect synthetic oil to provide the best fuel efficiency and horsepower, but it does come at a cost. In fact, it could be priced four times higher than conventional oil.

Most auto technicians agree that full synthetic oil should be used on vehicles that regularly tow, haul or drive in extreme conditions.

Synthetic Blend 0W-20 Oil

With a 0W-20 synthetic blend, you get the cost-saving benefits of conventional oil with some of the protections of the more expensive option. This oil is mixed with both conventional and synthetic options to create a blend. There are also additives included for more resistance.

This oil is one of the most popular today and regularly used during oil changes. It’s the middle ground for drivers who want more performance or fuel efficiency without breaking the bank.

Conventional 0W-20 Oil

Conventional oils were the standard many years ago. Today, this cheaper oil is only used for vehicles that don’t demand a lot of performance or efficiency. It’s the cheapest option on the market but not always the best for protection.

High-Mileage 0W-20 Oil

If your vehicle has more than 75,000 miles on the odometer, you want a high-mileage oil instead. This option reduces oil consumption, minimizes seepage and leaks, plus reduces emissions and smoke. It’s the ideal protection if you want your engine to last another 75,000 miles.

While these are termed high-mileage oil options, they are really just a specialized synthetic oil. However, there are normally added conditioners and protectants that help older engines last longer.

Best 0W-20 Motor Oil: Buying Guide

Before you purchase the first 0W 20 oil you see, you want to take these factors into consideration. It’s difficult to choose the wrong oil as long as you look at compatibility and the additives.

Motor Compatibility

The motor oil for a 5.7 Hemi is going to be different than a 6.7 PowerStroke. Not only does each engine require a different type of motor oil, but not all engines are compatible with 0W-20.

Thankfully, it’s not difficult to figure out what motor oil is best for your vehicle. Look on the oil cap of the engine or check the owner’s manual to figure out what’s recommended.

Your vehicle might also use more than one viscosity grade, giving you the option to choose from several motor oils. Some modern models allow either 5W-20 or 0W-20 to be used interchangeably.

Don’t ever use motor oil that isn’t compatible with your engine. Otherwise, you could create larger issues that might also require expensive engine repairs down the road.

Motor Oil Additives

The quality of motor oil you purchase relies heavily on what additives are included. Here are a few to consider.

• Anti-foaming agents: neutralizes air bubbles that can reduce oil quality.
• Antioxidants: prevent premature degradation.
• Anti-wear agents: Zinc dialkyl dithiophosphate (ZDDP) slows down metal degradation to extend the engine’s lifespan.
• Conditioners: softeners are ideal for high-mileage vehicles that are prone to oil leaks.
• Corrosion inhibitors: prevent acids from eating away at the internal components and creating rust.
• Detergents: removes debris and gunk from the oil.
• Dispersants: prevent blockage by reducing accumulating sludge.
• Friction modifiers: reduce friction under high temperatures or when hauling heavy loads.
• Viscosity index improvers: ensures the oil never loses integrity due to weather changes.

You don’t need to find a motor oil with all of these additives. Just look for the ones that suit your driving needs the best.
