What is the best way to take a sample for UOA when using an oil extractor?
I've been using an extractor for years, and I usually run the engine for a minute or two, just to stir things up. Then I let it sit for a couple minutes and let oil run back down to the drain pan and then suck it out. But I haven't been doing UOA.
I think Blackstone suggests not running the car for a short period because it could add fuel dilution to your sample. So do you just do it cold, or can you run the car for a while longer and do it hot? I've always been afraid to stick that plastic tube into a hot engine, worried it might melt. Is that a valid concern, or is it a high-temp plastic? I'm using an Oil Boy for extraction btw, in a '09 VW GTI.
Once I figure out hot or cold, I guess I can just suck out all the oil, then pour a little oil from the Oil Boy reservoir into my sample container. Is that how y'all do it?
Thanks!
