I never paid much attention to oil changes before, I just did them. There is however alot of discussion on this board about oil changes and that caused me to ponder the following.

If you run your motor until it is hot, then oil is distributed everywhere in the engine. When it has not be running (lets say overnight) it would seem more oil has settled into the pan and therefore by doing it cold more oil would drain (most likley slower).

In my case I thought about doing the first drain in the late afternoon, pull the oil filter, slide the cover back on and then in the morning do a second drain for whats left. Being I don't need ramps and can just reach under it, no big deal.

Am I missing something?
