I have always changed engine oil when its hot, or at least still quite warm after running the engine. I seem to recall as a kid it was always the way it was done. I am wondering whether this was a result of higher viscosity single grade oils used back in the day.
Right now it will be more convenient to do an oil change with a cold engine, via the oil change pumpout system. Its easy to turn the pump off, come back after 30 minutes and turn it back on to get the last little bit out.
Just curious as to what most folks do, hot or cold changes. And if anyone like Ski has sound reasons for not doing cold oil changes. I've heard of particulates not draining out with cold oil but figure that if there were any particulates around then they would end up in the oil filter, so not too concerned about that.
