I just read an article in the September 2019 issue of Road Racing World that discussed whether to change your bike's oil hot, warm or cold.
The testers went to a lot of trouble to measure and control how much oil went in and how much came out, including what was left on the funnel and the bowl the oil was drained into.
The conclusion: Cold - More oil drained out cold. And they determined the amount of contaminants left behind was less than either the hot or warm drain scenario.
The article is titled "Draining Engine Oil: What's Better? Hot or Cold?" by Jason McDonnell.
Interesting as everything I've read in my owner's manuals talks about getting the engine up to operating temperature before doing an oil drain, i.e. hot.
It sure would be easier doing the drain cold, especially on our new K1600GT Sport.
Thoughts?
