Question: Does It Matter If I Put 5w30 Instead Of 5w20?

Can you use 5w30 instead of 5w20?

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..

Is it OK to use SAE 30 instead of 5w20?

The first one/two digits always refers to the viscosity rating at the lower threshold for oil temperature and the second two digits refer to the viscosity rating at the upper threshold for oil temperature. … So, yes, you will be fine by running a 5W30 oil on an engine rated for 5W20 oil.

What happens if you put 5w20 in a 5w30 car?

Probably not. 5w20 oil is fairly light oil and is generally designed to work with newer engines. Motor oil has become part of a manufacturers program to allow engines to get higher fuel mileage.

How much thicker is 5w30 than 5w20?

This enables the 5w20 motor oil to reach engine parts quicker and create less drag that reduces fuel economy. So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

What happens if you put the wrong oil in your car?

You might notice a few oil spot in your garage or under your car because using the wrong oil can lead to leaks, or you might become aware of a burning smell while driving. If the oil isn’t working as it should engine parts might not be lubricated well enough and cause friction, which can burn the oil.

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.

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?

You can mix a 5W20 with a 5W30 oil with minimal amount of issues provided it the same manufacturer and the same API classification. The question is ‘why would you?” If it is because you oil is low and the only thing available is a different grade then it might be fine until you can get it changed.

Which is better 5w30 or 5w20?

The key difference between 5W20 and 5W30 motor oil is that the former is thicker or less viscous. … The more viscous motor oil is, the better it will be able to resist the heat and not break down. In this case, 5w30 oil will provide better overall engine protection than 5w20.

Is 5w20 good for high mileage?

Generally, you should use the oil that is recommended in your manual. If the manufacturer recommend 5W20 — you should stick with it. … Finally, some manufacturer have “High Mileage” grade oil. These are said to have additional additive specifically formulated to help engine with over 75,000 miles.

What is the difference between 5w30 and 5w20?

The main difference between 5W-30 and 5W-20 motor oil is that the latter gives a slight bump in fuel efficiency. When used in a vehicle’s engine, 5W-20 oil creates less friction due to its thinner viscosity (or thickness), meaning it drags less across engine parts like the crankshaft, valvetrain, and pistons.
