Quick Answer: Is 0w20 Better Than 5w30?

Will 5w20 hurt a 0w20 engine?

Both 5w-20 and 0w-20 are IDENTICAL once the car is up to temperature.

The difference is how thin those oils are when the car is cold.

Neither the 0w or the 5w flow enough in the cold to properly lubricate your engine.

However, the 0W is thinner and does LESS damage at start up than the 5W oil..

Will thicker oil damage my engine?

Not only that, but the engine will waste energy pumping the thicker motor oil, reducing fuel economy. Since thicker oils don’t transfer heat as well as thinner oils, operating temperatures will increase, too, possibly leading to accelerated chemical break down and harmful sludge and deposits.

Is it OK to mix 5w20 with 0w20?

They only spec 0W20 so they can report slightly better fuel mileage, but your engine will wear faster. It won’t make any difference that you will notice or be able to measure. Any effect would at extreme cold temps and this is a miniscule change in viscosity. There is nothing to be accomplished by mixing 0W and 5W.

Is 0w 20 oil too thin?

A 0W-20 oil seems too thin and I’m very skeptical. … Answer: Yes, 0W-20 is unquestionably safe for your engine. Manufacturers have been specifying 5W-20 and 0W-20 since the early part of the last decade and there is no evidence whatsoever that engine wear rates have increased.

What type of oil is 0w20?

synthetic motor oilMobil 1™ 0W-20 is an advanced full synthetic motor oil designed to help deliver outstanding engine protection and enhanced fuel economy benefits to keep your engine running like new and protect critical engine parts for up to 10,000 miles between oil changes*.

Should I use thicker oil in a high mileage engine?

A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil – 10W – can help protect worn engine bearings as well.

Is it OK to use 5w30 instead of 0w20?

0w20 is a fully synthetic motor oil. 0w being the winter weight, the viscosity of the oil at freezing temperatures. … 5w30 can be fully synthetic, however, putting it into your engine which is designed for 0w20 is a bad idea. If it isn’t on the fill cap don’t put it in your engine.

How long does OW 20 oil last?

A: Toyota models that require synthetic oil have this statement in the Owner’s Manual: “SAE OW-20 is the best choice for good fuel economy and good starting in cold weather.” The original oil change interval stated in the manual for OW-20 vehicles was 5,000 miles/6 months.

When should I use 0w20 oil?

Temperatures and certain climate conditions affect the use of 0W-20 over the 5W-30 engine oil. During summer, viscosity becomes higher, and during winter, viscosity becomes lower so that why it’s preferred to put the OW-20 in summer seasons.

Why does Toyota use 0w20 oil?

To reduce friction 0w20 oil is used. The main reason is friction reduction and fuel efficiency. Lighter oil, less friction engine rotates faster.. better fuel economy.

What happens if you put wrong oil in car?

The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. … Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.

Which is better 0w 20 or 5w 20?

Sure, 0W20 will flow better than 5W20 at low temperatures, but the difference is minimal and both versions run thin in cold conditions. However, if you live in an extremely cold region, the 0W oil will do less damage than the 5W oil while starting the engine.

Does 0w20 damage engine?

So moving one grade of oil is not going to destroy your engine or void your warranty. But you will want to use the right oil to not damage your engine. So don’t go the wrong way and use something too thin when it is hot or too thick when it is cold. Most folks would be better off just using what the manual calls for.

Will 0w20 hurt a 5w30 engine?

0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine.
