its not about speed of drain starting the engine prior to oil change
> its about the crap being agitated and suspended in the oil
I don't think he cares about obtaining or giving basic car maintenance help. He's more interested in plugging his scum bag website, the filthy spamming f*ck that he is.
I always find it's best to change the oil without the engine running.
That's how I read it!
The message from "Angus Manwaring" contains these words:
Yes.
Crap is mostly heavier than oil. In warm oil it will sink faster. Generally crap will be in the filter or in the sump already. Running the engine to warm it up won't scatter it all round the engine unless you are into some serious off roading.
But it will mean that (some of) the last dregs of oil in the sump come out easier and bring the crap with them instead of staying stuck in the sump.
Mnay thanks for the helpful and informative answer.
All the best, Angus Manwaring. (for e-mail remove ANTISPEM)
