Most owner's manuals will advise you to check the oil level when the engine is warm (after driving 10 or 15 minutes), about 5 minutes after you stop the engine. This allows the warmed oil to be fully circulated in the engine, and then drain down to the oil pan where its level can be measured by the dipstick. You should never add more oil than you need, as indicated by the dipstick.
Cold
On the dipstick there is a safe range. You can check it either hot or cold. When cold the level should be close to the bottom of the safe range. When hot it should be close to the top of the safe range.
Check engine oil when you have just finished driving. Check Transmission fluid when the car is running and the transmission in in N (manual) or P (automatic).
You check the transmission fluid when its hot
cool the oil heats up and expands u need it cool to get a accurate reading
vinigar is not hot nor cold its like oil xD!! who luvs pie!!! i do!!!!
No, that is not recommended at all.
Normally your dipstick has a hot and cold mark on it. If not check it hot, always check it with the engine running on an even surface.
You don't check it cold, check it hot and it should hold 3.5 quarts...and on the stand or level doesn't matter....warmed up engine and anywhere on your dipstick is good.
To check the oil on bikes you normally have to run the engine for a few minutes, the turn it off and let it sit for a few more minutes, and check the oil with the bike standing straight up.
You can check it when the engine is cold and you should check the oil level in your engine when the engine has sat for at least 30 minutes. This way all the oil has drained back into the oil pan and you will get an accurate reading on the dipstick.
Check the oil after the engine has not been run for at least 30 minutes.
