Some people still don't get it! drain it hot as all the particulates ARE STILL suspended in the oil so it all drains out,cold oil drains slower leaving the crud at the bottom of the pan

I put my used oil in a five gallon gas can. When the can is emptied there is a layer of crud in the bottom. Granted the can may set for a month before I take it to be emptied, but there is still some settling. This would have to happen to a small amount with cold oil in the oil pan. This is why I justify to myself that I need to get hot oil on my hands at every change. The fresh oil would most likely clean up the small amount that cold oil might leave, but I still feel better changing it while the oil is still "stirred up".

With my KJ, I change it cold. I would prefer to change it hot, but I get a lot of nasty drivetrain noise when I drain out hot oil and put in room temp oil and start it. I could drain the hot, put the new in and wait until the next day to start it, but I don't always have the luxury of waiting until the next day to go somewhere.


What is a T&C or a kj?
