Default Blackstone Labs Report - Was missing airfilter - 11-07-2017, 03:07 PM

A while back I noticed my air filter was missing. No idea how long it was gone for. Thinking it was at least 3,000 miles. but I also flog this thing hard up to 23PSI stock turbo at low RPM's etc, long oil change. Engine has about 88k miles on sample. Noted that I have to add a quart at about 5k miles.


Decided to use Blackstone since I used them in the past for diesel engines (eg. Cummins, *** C15's). They were pretty accurate for me on a million mile *** C15.

Was thinking if they thought metals were bad, was going to stop messing with this car and get something else. Now I'm thinking it's really time to go PS2!

Anyone else do oil samples?
