Question: Is 5w 20 Or 5w 30 Thicker?

Can I switch from 5w20 to 5w30?

Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output.

You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil..

Can you mix different oil viscosities?

THE ANSWER IS NO! Even if two different brands of oil have the same viscosity, you still should not be mixing them together.

What happens if I put 10w40 instead of 5w20?

In a 5W20 engine. You could use a 0W20 oil (I use 0W20 oil) in cold weather and it would be Ok by Ford. (they will not say it is good, but they will still honor the warranty..) But 10W40 is way off, and I bet they would be not so happy over any engine problems if they found 10W40 in a failed engine.

Is it bad to put 10w30 in a 5w30?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

Is 5w 20 thicker than 10w30?

The motor oil is categorized according to its viscosity. Whether the oil is thicker or extra thinner, it specifies the type of engine it is suitable for. There are hundreds of oils but 10w30 and 5w20 are the most common of all. The 10w30 type is the thicker one and 5w20 is the thinner.

What happens if you put the wrong oil in your 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.

Can I use 5w30 instead of 5w20 in my Kia?

Banned. All KIA dealers I’ve ever been to use 5W-20 semi-synthetic. The only 5w-30 they had was fully synthetic. You should use 5W-20 if you have an EX.

When should I use 5w30 oil?

At operating temperatures, both oils will have the same viscosity (30) and will flow and protect identically. If the oil will be in the engine during winter and you live in a place where it gets cold during these months, use 5w30 oil. If it will only be in the engine during the summer, use 10w30.

When should I switch from 5w20 to 5w30?

On a vehicle engine with 5W20 printed on the oil fill cap…. If the engine was originally designed to run 5w-30 then make the switch immediately. See if any of your engines were back specced from 30 to 20. Oil fill cap is not stamped by the engine designers.

What happens if you mix 5w20 with 5w30?

It won’t hurt a thing. These are both multi-viscosity motor oils, meaning they can cover a range of temperature and load conditions. 5w30 has a bit wider range of components than does 5w20, but that’s okay. It won’t hurt a thing.

Will 5w30 hurt a 5w20 engine?

There is no harm in using 5W30 instead of 5W20.

Can you put 10w30 in a 5w20 engine?

Originally Answered: Can I put 10w30 instead of 5w20? You can, but you will get worse mileage, and in most cases shorten the life of your engine, as it will take longer to pump up pressure for your bearings and lifters, and won’t spray your lower cylinders for an extra second or so on each cold start.

What happens if you put 10w30 instead of 5w30?

Your oil is a little thicker when cold. No damage will happen. … The 5W and 10W defines how the oil will flow at 0 degrees. At operating temperature, there will be a completely insignificant difference between the two.

Which is better 5w 20 or 5w 30?

The thicker 5W-30 should see a slight advantage when operating at higher temperatures, while the thinner 5W-20 oil should provide better engine protection at lower temperature levels and has the added benefit of slightly improving fuel efficiency.

Is 5w20 good for high mileage?

​5w30 or 5w20 for high mileage 5w-20 or 5w-30 oil can work effectively with a high mileage car.
