I've never personally broken down an engine into its component parts but I'm willing to bet that anyone who has, found oil in the engine somewhere.

I say instead of bickering back and forth, next time I change my oil, I'll switch from an oil pan to a measuring cup after 5 minutes. I bet there will be more than half an ounce after 25 more minutes. I also have a feeling if you did a UOA of the first 5 minutes and one from the last 25, the last 25 would be considerably dirtier. I've seen some pretty dirty chunks fall out after 5 minutes.

Like I said, I'm not arguing Jiffy Lube any more. Its your car. Just don't read all the horror stories about wrong fluids and such. I'll continue getting a cheaper, and better(however marginally it may be) oil change.

pour it in a jug from the last oil change and take it down to kragen
