One of the low-temperature grades added to the SAE J300 EOVC system after 1952 is 0W20 motor oil (0W20 oil). It is a liquid designed to behave as an SAE 20 once the engine reaches its operating temperature but flow as easily as an SAE 0 in subzero conditions.
Even at -35C/-31F, this type of oil will still start to flow through the engine’s oil channels. This oil lubricates important engine components, making it simpler for you to start your engine cold in the winter.

W20 vs 5W20 Fuel Economy
Another low-temperature grade often advised for winter use is 5W20 motor oil, with 10W-30 serving as an option for higher temperatures. Because it offers the best fuel economy, reduces fuel consumption, and produces fewer exhaust pollutants, this oil type is widely used. Motor companies and governments all around the world, led by those in Japan, Europe, and the US, are looking for 5W20.
Low viscosity, high-quality synthetic grades 0W20 and 5W20 can both significantly improve fuel economy. When employed in fair-weather temperatures, their attributes are identical. When utilized in cold temperatures, there is little to no difference between the two variants.
Why do automobiles utilize 0W20?
Modern car engines, which are smaller and work at higher temperatures than previous engines, require 0W motor oil to function properly. Synthetic base stock is often needed to match industry and OEM criteria in order to create a 0W motor oil and is consequently only offered as a synthetic motor oil.
The advantages of using the proper 0W grade motor oil for your car include better fuel economy compared to higher viscosity grade oils, faster flow at startup to reach vital engine sections, and quicker engine warm-up.
Is 0W20 harmful to engines?
an inquiry from a reader “For my new pickup truck, the recommended engine oil is 0W-20. This is a significant adjustment for me because I have never owned a car that required anything other than 5W-30. 0W-20 oil appears excessively thin, and I have serious doubts. I requested that my dealer allow me to use at least 5W-20, but they claim that 0W-20 must be used in order to keep my warranty in effect. For my new engine, is 0W-20 safe?
Answer: Without a doubt, 0W-20 is safe for your engine. Since the beginning of the previous decade, manufacturers have required 5W-20 and 0W-20, and there is absolutely no proof that engine wear rates have gone up. Engine wear has never been lower because of the enormous advancements made in the last 15 years in engine designs, materials, and motor oil chemistry. The 5W-20 and 0W-20 grades are quickly replacing the 5W-30 grade in new cars. A brand-new car with the specification 5W-30 will be uncommon by the end of this decade. In fact, in the upcoming years, anticipate to see even lower viscosities, such 0W-16.
Why do auto manufacturers advise using thinner motor oils? merely to maximize fuel efficiency. However, this pattern has persisted long enough for us to draw the conclusion that there are no negative effects in terms of shortened engine life.
Regarding the second half of your query, which asks whether it is advantageous to use 5W-20 instead of the advised 0W-20, we see no justification for doing so. Let’s utilize the characteristics of the 0W-20 and 5W-20 AMSOIL Signature Series oils to demonstrate our point.
The measured in is the industry standard for assessing viscosity at operational temperature “at 100C, centistokes.
- 8.7 centistokes for AMSOIL Signature Series 5W-20.
- 8.8 centistokes for the AMSOIL Signature Series 0W-20.
The 0W-20 and 5W-20 are consequently nearly equal in terms of thickness or viscosity at working temperatures. Because it would provide a very minor increase in terms of cold weather start-up protection, the car maker chose a 0W-20 oil.
We choose a 0W-20 for year-round use even though our daily driver requires a 5W-20 in order to have the optimum start-up protection. Even in sweltering weather, we observe absolutely no oil usage in between oil changes.
In conclusion, you may be sure that a high-quality 0W-20 motor oil will provide the best wear control. Enjoy your new truck, and you may use 0W-20 motor oil with confidence.
What kind of oil should I use in a Toyota?
Toyota vehicles should use the following Toyota Genuine Motor Oils:
- SAE OW-16 synthetic motor oil from Toyota.
- SAE OW-20 synthetic motor oil from Toyota.
- SAE 5W-30 Motor Oil for Toyota.
- Motor One 5W-30.
- The formula is Mobil SuperTM 3000 X1 FE 5W-30.
How frequently should 0w 20 oil be changed?
The manufacturer has approved an oil change interval of 10,000 miles or 12 months for Toyota vehicles that utilize 0w-20 synthetic oil. When using this type of oil, vehicle owners should periodically check the engine’s oil level and top it off as necessary. This will enhance the effectiveness of the synthetic oil. The 10,000-mile oil change interval has NOT been approved by Toyota if you operate a Toyota Tundra or Toyota Sequoia that is fitted with a flex fuel-compatible engine.
Some engines may safely run on 0w-20 synthetic oil despite being tuned to run on 5w-20 mineral oil. Even if synthetic oil is used, these engines will still require the 5,000-mile/six-month oil change period.
Other maintenance tasks
Owners shouldn’t disregard the other maintenance requirements of their car just because it has a longer time between oil changes. Despite the fact that the oil only needs to be changed once a year, or after 10,000 miles, the 5,000-mile services are still necessary. This would cover procedures like brake inspections and tire rotations.
Toyota continues to demand the 5,000-mile/six-month interval from owners who frequently make short journeys in below-freezing weather, drive on dirt roads, off-road, or tow big loads. Even if an owner uses synthetic oil, this is still true.
Does my Toyota require synthetic oil?
There are two sorts of oil in the world, regular and synthetic, apart from different viscosities. Although there is a third variety that combines the first two, you often deal with either one or the other. The best option for your Toyota? What kind of oil is used in your Toyota? We offer all the solutions you require.
Does a Toyota need a specific kind of oil?
At this point, all current Toyota vehicles either require synthetic oil or at least recommend it. You must reference your manual to be certain. However, if you only decide to use synthetic oil, it will be far better for your engine and will simplify everything.
Is 0W 20 suitable for hot climates?
The thinner oil grades 0W-20 and 5W-20 both work best in cold winter climes.
The 0W-20 oil grade performs better with cold starts due to its reduced viscosity. Additionally, it guards against issues including varnish buildup, engine wear, sludge formation, and low oil pressure. With 0W-20, you may anticipate faster oil circulation and a smoother flow.
Therefore, 0W-20 oil grade would be the best choice for you if you plan to travel frequently in regions with below-freezing temperatures and infrequently in regions with higher temperatures.
However, 5W-20 performs a little bit better in seasonal climates due to its higher viscosity. Because of its somewhat greater thickness, it resists oil thinning at higher temperatures better.
There are some vehicles that can use both 0W-20 and 5W-20 oil. However, consult with your mechanic regarding the suggested oil for your vehicle before switching to a different viscosity grade.
Which is preferable, 5W-30 or 0w20?
Pay particular attention to the quality testing done while selecting a motor oil. Both the API donut and the starburst sign should be visible on the packaging.
The American Petroleum Institute’s testing was successful, as evidenced by the API donut. The starburst is also used to demonstrate eligibility for SL service.
Location
You must take the region into account while selecting the ideal oil viscosity from the suggested possibilities. For instance, 5W20 can be used in somewhat warmer settings while OW20 will perform better in cold climates like Maine or Alaska.
Having knowledge of the temperature range aids in selecting the proper oil. The temperature range for 0W-20 oil is -40 to 68F. In contrast, the operating temperature range for 5W20 oil is -31F to 68F and for 5W30 oil is -31F to 104F.
Fuel Economy
Because the lubricant flows more easily, the higher the fuel efficiency, the thinner the oil viscosity. As a result, 5W20 will run similarly to 0W20 once the engine has warmed up, but 0W20 will be more fuel-efficient during startup.
In both colder and warmer climates, 0W20 offers greater fuel efficiency than 5W30. However, 5W20 only performs better than 5W30 in hotter environments.
You can give the engine the protection it needs to last longer by using the proper oil in it. Make sure you do your study before selecting oil to attain the performance level you need.
What oil is an alternative to 0w20?
In stead of 0w20, I wouldn’t think twice using a solid 5w20. The only thing that *could* be a problem is if you experienced a probable lubrication-related problem and a dealer or Subaru asked to see the receipts for your oil changes and they indicated 5w20.
It would be extremely challenging, if not impossible, for them to distinguish between a well-used 0w20 and a 5w20 in the sump in the event of a used oil analysis.
Does full synthetic 0W-20 oil always exist?
High quality base oils and potent additives are required to manufacture a 0W-20. At very low temperatures, the basic oils must still be able to protect and flow. For the oil to flow smoothly at these low temperatures, a lot of synthetic oil is typically required. 0W-20 motor oils are either fully synthetic or partially synthetic (synthetic blend) and need synthetic base oils; they are not conventional (or mineral) motor oils. And the additives must be light enough to move easily while still guarding these more modern, sophisticated motors.
Can I combine 5w30 with 0w20?
THIS. And now that it’s been a warmer summer, using 5-30 greater protection won’t be a problem. However, I wouldn’t use it if my car had less than 40k miles and was a 2010 model or newer. However, mixing it should be safe; it will guard against damage.
Which motor oil is the best in the world?
In comparison to regular motor oils, this premium synthetic oil from Amsoil offers 75% greater engine protection and 50% more cleaning power. Additionally, turbocharger protection is improved by 72%. This Signature Series synthetic motor oil, which was designed for thermal durability, resists breakdown and regulates heat to prolong engine life and enhance overall performance for up to 25,000 miles.
What drawbacks does synthetic oil have?
The following are a few drawbacks of synthetic oil to be aware of: Cost is arguably the most obvious drawback of synthetic oil. The cost of synthetic oil is often two to four times that of regular oil. When kept in a cold storage environment, synthetics may be more susceptible to additive precipitation.
How many miles between oil changes does Toyota advise?
Toyota advises changing your oil every 10,000 miles, but that you should keep the 5,000-mile service intervals for fluid top-offs, inspections, and tire rotations.
