When doing an oil service is there any difference between draining the oil when it's cold or draining it when its up to operating temperature?
I always made sure the engine is hot, but does it actually make any difference?
How about in the winter, when it is cold outside? 0W20 seems to flow very easily even at 0C. Do I need to warm up the engine first?
