What check engine level means?

The check engine oil light could come on if the system is experiencing low pressure due to a bad oil pump, for example. This could mean that oil supplies are depleted or that the system isn’t circulating adequate oil to keep the engine lubricated.

What is the correct engine oil level?

The engine oil level should be in the cross hatch section and at or slightly below the full mark when the engine is cool. If the engine oil is low, it could indicate the engine is either leaking or consuming oil.

What’s the difference between 5w 20 and 5w 30?

5w30 motor oil, the 20 indicates that the oil has a lower viscosity and is thinner at higher temperatures. So, due to viscosity, 5w20 is a thinner oil during operating temperatures, whereas 5w30 is thicker during operating temperatures.

Does oil level go down when hot?

Regular oil will experience normal expansion and contraction, which means you will get around the same readings regardless of temperature. Newer cars with electronic oil level controllers will only measure the engine oil when warm and stay at a flat surface level.

What if oil level is too high?

When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.

How do you know when your oil is low?

With the engine off, open the car’s hood and find the dipstick. Pull the dipstick out from the engine and wipe any oil off from its end. Then insert the dipstick back into its tube and push it all the way back in. The dipstick shows the oil is low and needs to be topped off.

Should I check oil hot or cold?

If checking the oil yourself, make sure the car is parked on level ground and, with most cars, the engine is cold, so you don’t burn yourself on a hot engine part. (With some cars, the automaker recommends that the oil be checked after the engine has been warmed up.)

Can you mix 5W-30 and 5W20?

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.
