Quick Introduction

The engine is the heart of your vehicle. It’s where all the work happens to give you a smooth, comfortable, and safe ride. For that reason, maintenance of the car engine is crucial regardless of what vehicle you have. And to keep it well-maintained, you must choose only the best oil — synthetic oil, to be exact.

Why? Although you can use just any regular motor oil, the synthetic type of oil is the most suitable pick because they provide maximum performance and superior cleaning. If you want your engine to last long, using full synthetic engine oil would be your best move. 

As you probably know, there are different viscosity grades for motor oils. You’ll see something in the label like “15w-20” or “10w-30”. But in this case, we’re looking at 0w-20 simply because they’re the most recommended by automotive manufacturers.

If you’re wondering what all the numbers mean, we’re here to explain in the reviews below. For filter recommendations, see our list of best oil filters for synthetic oil.

Top 5 0w-20 Synthetic Oil – Reviews & Buying Guide

Take a look at one of the best synthetic oils, the Castrol 03124 EDGE 0w-20. With a Group IV base stock, it’s a full synthetic motor oil that will take the best care of your car. It’s suitable for gasoline and diesel engines, so there’s no compatibility issues there. 

We love how cost-effective using the Castrol EDGE is. Although it comes in a cheaper price tag, it doesn’t compromise on the work it does. Quality lubrication improves the overall performance of vehicles. In fact, it’s ready to face extreme engine pressure even from newer engines, thanks to Castrol’s patented titanium fluid technology. The titanium tech ensurse a boost of strength that allows your motor oil to last a longer time under high pressure and vehicle wear and tear. You’ll have maximum fluid viscosity at all times, because this full synthetic motor oil is three times stronger than others at fending off breakdowns.

  • Handles extreme pressure with titanium fluid technology
  • Better lubrication and viscosity for preventing wear and tear
  • Designed with superb oil cleaning capabilities.
  • Great price


  • Not the best oil for a cold start

As for engine cleaning, the  Castrol 03124 EDGE is also one of the best. It effectively works and flushes out all the dirt, sludge, and other deposits that cause harm to your car engine. Dispersant molecules included in this product take cleaning to another level so oxidation and corrosion would not take place.

Combustion is a messy process by nature, so you absolutely need a full synthetic motor oil that cleans like a pro. With high quality formulation plus good cleaning additives, this motor oil also reduces deposits by 42% — that’s better than the work others provide for vehicles. When dirt and debris are out of the way, this best synthetic oil brand can better lubricate the metal parts to ensure they won’t wear out fast.

3 – Pennzoil Platinum 0w-20 Full Synthetic Motor Oil

The first thing we noticed about this full synthetic oil is its ergonomic container. While other brands (like Valvoline) are typically in a one-handle container, this has full double handles. That makes it easier to put in your engine/

But of course, the engine oil performance matters a lot more than the 5 quart container it’s available in, and the Pennzoil 0w-20 does not disappoint.

It comes with a base oil made from natural gas, so it’s definitely one of the cleanest and best synthetic oils in the market. It’s astonishingly clear because it’s using fewer impurities found in crude oil, which is used in many conventional oil formulas and even some great synthetic ones.

Pennzoil has also used its patented PurePlus Technology in the oil product which involves a gas-to-liquid process that works to convert natural gas into a fully synthetic base oil. High-performance additives are then combined to the base oil to create a great quality oil that offers better engine protection. 


  • Outstanding cleaning action
  • PurePlus Technology
  • Protects engine from wear and friction
  • Good viscosity, flows smoothly even in extreme temperatures


  • Less mileage compared to other engine oils          

That said, Pennzoil Platinum is the best synthetic oil in the market for those who prioritize a clean engine. A natural gas base, PurePlus Technology, and top-of-the-line additives all work together to protect your engine from sludge, varnish, and grime. Thus, less deposits for an excellent run. 

Based on a Sequence IIIH engine test, Pennzoil Platinum keeps pistons up to 50% cleaner than the toughest standards available in the industry. Customers have backed this up as well, and they are delighted that the oil comes out almost clear when it’s used up and time for an oil change. 

As for temperature handling, the Pennzoil Platinum performs excellently, much like the Valvoline 0w-20 Synpower Full Synthetic Oil. You’ll find that oil flow is still good and smooth even in low temperatures or in extreme heat. Whatever the weather, you can depend on this 0w-20 best synthetic oil to protect your engine against cold starts and breakdowns. As for cons, mileage is just not that great compared to others.

4 – Royal Purple 51020 API-licensed SAE 0w-20 Synthetic Motor Oil

Royal Purple is one of the brands that first comes to mind when it comes to the best synthetic oils. It comes alonside brands such as Mobil 1, Valvoline, etc. It has climbed to the top by working with race cars — so it’s not a surprise that their synthetic motor oil is designed to perform well even under high pressure. 

The Royal Purple 51020 is a 100% synthetic oil brand that works to provide great protection for your engine. With premium base oils plus proprietary ZDDP additives, it coats components to prevent metal-to-metal contact, ensuring reliable performance and preventing wear. All Royal Purple SAE 0w-20 engine oils are made with zinc/phosphorus compound zinc dialkyl dithiophosphate (ZDDP) because of its benefits to engines. 

For one thing, ZDDP is designed to prevent the formation of rust by acting as a barrier against moisture. It’s also an anti-wear additive, meaning it adds an additional layer of lubricant which helps when the oil thins with high temperature. Operating conditions give way to a rise in temperature, which reduces the oil’s strength and lubricating properties.

But because the Royal Purple 51020 product is using ZDDP, the engine oil will still improve the performance of your engine despite hot conditions. Another thing, ZDDP also inhibits oxidation, therefore allowing you to maximize the use and life of this best lubricant. It would take more time before your next oil change, making it better than most oils.


  • 100% synthetic
  • Protects against corrosion
  • Can handle high pressure
  • Compatible with synthetic and conventional oils, even fuels containing ethanol
  • Fuel-efficient oil

Whether you have a gasoline or diesel engine, you’re good with using the Royal Purple.

Fuel efficiency is important to consider when choosing the best 0w-20 synthetic oil. This reduces fuel consumption so you get to save more and drive further. Some users even report getting to 12 000 miles!

It’s API-licensed and meets the requirements of ILSAC GF-5 and Dexos1, so you’re sure to get only the best performance from this oil product. The only downside is the oil isn’t recommended for all vehicles. The best 0w-20 Synthetic Oil is the Royal Purple 51020.

How to Choose the Best 0w-20 Synthetic Oil

Check the label

Understanding what the product label says will tell you basically everything you need to know about a 0w-20 synthetic oil and what it comes with. Aside from the 0w-20 viscosity grade, you may also find out what the synthetic oil “prioritizes”. If you see “Fuel Economy” or “High-Performance”, it gives you an idea of what the oil comes with and what it’s made for. More importantly, find out its compatibility if it suits the need of your engine. 

Car type

Keep in mind what your car type or model is to get an idea of what oil suits it best. Not all synthetic motor oil is right for every car and every engine. Some are only good for diesel, some only for gasoline. In many cases, there are great oils that are specifically engineered for some car types. If you don’t want to get too much into many technicalities, you can just look for an oil that says it’s a perfect fit for a Honda, Toyota, Acura, Lexus, or whatever your car is. Also know that not all are right and good for the break-in process in vehicles, so you might want to choose something better for the job if your car is new.


There are many different kinds of additives used and recommended by companies, so make sure to check which ones are infused in your motor oil. There are antioxidants, rust and corrosion inhibitors, viscosity index improvers, anti-wear agents, extreme pressure additives, detergents, dispersants, friction modifiers, and more. 

Know your needs

What do you really look for in a high quality motor oil? High mileage? Fuel efficiency? Performance? Consider your needs and preferences to help you narrow down your choices and get to the right one.


As always, the right price is something that should be considered before making a buying decision. Not all cheap motor oils are lax, and not all expensive motor oils are the best. In order for you to choose the best 0w-20 synthetic oil, keep in mind what you need and what it brings to the table before looking at the price range.

What does 0w-20 mean?

0w-20 is actually a code for oil viscosity as classified by the Society of Automotive Engineering (SAE). You may have seen “0-20 oil” or “0w20 oil”, these all mean the same.

The “w” in viscosity refers to winter classification, and the preceding number refers to the temperature at which the oil is able to flow smoothly. This is essentially the oil’s resistance to low temperatures, so when you get a lower number in viscosity such as 0 (which is the lowest rating) that means the oil will still flow  at a low temperature (i.e. 0 degrees Fahrenheit). On the other hand, the second number “20” refers to the oil’s resistance to thinning at high temperatures. Generally, the higher the second number in viscosity, the better the oil will perform in high temperatures.

It’s also worth mentioning that it’s recommended to get a synthetic oil with Group IV or V base stock, meaning it’s purely synthetic and not just a synthetic blend.

In a nutshell, 0w-20 engine oils are the best at handling extreme temperatures and conditions. So if you don’t want your oil freezing over during the winter, it’s a great choice.  Plus, it provides reliable protection against engine wear and oxidation. 


With all the reviews above, 0w-20 oils are not made equal. You should still take some time to research for the best 0w-20 synthetic oil for your vehicle. So, we’ve selected our top picks for 0w-20 oil to help you make the right choice. You can also check our top-rated suggestions for diesel oil here.
