Length of Oil into Pan, Checking Oil Options

[JoKeRkId613]

I usually check my oil once a week. I want to make sure I'm doing this right. I check my oil after a normal drive, turn off the car, and wait 15 minutes before I check the oil. I do this because I was told I should wait till all the oil goes back into the oil pan. Is this a good amount of time to wait? I ask because TRD recommends I check my oil at every gas fillup and the "checking process" happens right after I turn off the car, meaning the oil hasn't had any time to go into the pan - I hope TRD doesn't expect me to hang around a gas station for 15 minutes to check my oil. So this is what caused me to wonder the best amount of time to wait before checking my oil after turning the car off. Anyone know?

Thanks. Just want to make sure I'm getting the most accurate reading and don't overfill.

its a C240 iirc, newer model. there is no oil dipstick that comes with the car, just a dealer only tool which is spec specific to the particular engine/engine configuration...its nothing more than a dipstick. but its only available to dealer service depts...otherwise you need to measure what comes out, and put that much back in. we NOW know how much it takes, but when going by the spec provided by our computer data (alldata or shopkey) we got overfill messages. the overfill only trips after a certain number of engine starts. the engine reads the oil level at key on/engine off after the engine has been off for x number of minutes. only ****ing mercedes would make a car without a dipstick!

Ah there it is.
More BS money making scams - I was just speaking of another one. Too much of that going on these days. I suppose they'll void the warranty if the oil level is insufficient or overfilled?
