interesting conversation about draining oil

[Django]

No thermodynamics talk needed, you just missed the point I'm trying to suggest here: I think you'll get more oil out of your bike by draining it cold, rather than hot. My theory is simply based on where the oil is when it's cold vs hot.

You could drain the oil when it is hot and after letting the motor run. That would give you the advantage of a more fluid oil and all the particles dispersed in the oil.

Then you could let it stay open over night. That would give you the advantage, all oil collects in the sump and get drained, as you assume it is in a cold engine.
