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.
