I just purchased my 06 4.8, I do not know when or what type of oil was used in her for the last change..... This bothers me! I like knowing what is what in my cars!
I would never chance it in my races cars, do you take the chance here? I mean its not like I drive aggressively in my X....

I am thinking about just dropping it and know what I have.....
For the captain's of obvious, yes I checked the level, no I didn't taste it, yes I know what the book says on oil

, and on, and on, and on....... You guys know these SAV's like the back of your hand, so, opinions please?
