Checking your Oil Level

How do you guys normally check your oil level??
Manual stated to check the oil when it is warm. Wouldn't the oil be sloshed around?

I have always checked the oil level when it is cold? or after it has been sitting for a while.

I would figure checking it cold would be the best way to get an accurate reading? I have the 5.3l engine so which is correct? If check when It is cold my oil level is in the middle.. If I check when it is warm. my oil level is over the maximum amount.

at operating temp- shut off engine- and let it sit for a few minutes to allow oil to make its way back down to the oil pan- check oil.

Yes, my 05 manual states the same thing. I've never understand that. I've always checked the oil in my vehicles before driving in the morning.

Check it while you are fueling your truck. Oil should be warm and will have a little time to settle while you start filling the tank.

Could someone please explain to me WHY it should be checked warm? Are you saying oil expands as it gets hot?

For many decades I've been checking it cold. That way ALL the oil has drained down into the oil pan.

It should be checked at it's point of greatest volume. As all of us old school guys remember that if the crankshaft comes into direct contact with the oil in the pan the results are not good. That's why people die when they jump off bridges .... liquids are like cement at high velocities.

Yes, but do you remember the dipper sticks on the crank shaft, the splash system????? (216 chevy for one)

the reason to check your oil warm is because you should check your oil at normal operating temperature. it will give you the most accurate results. too hot, your oil level will seem a bit high. too cold your oil will seem too low. too much oil in your motor will cause a negative effect just as running a vehicle with too little oil.
