2005 Ford Freestyle AWD 3.0 70K miles
I got on the BITOG bandwagon, and got myself some $5.00/gallon oil
Pennzoil Platinum 5W20/ Motorcraft FL820S filter.
The car's seen nothing but Motorcraft Synblend 5W20 on OCI's averaging around 5k (still under warranty). From what I can see through the valve cover (not much) and dipstick, it certainly looks spotless. With 5K OCI's and that motor, I think I could put grapefruit juice in there and it wouldn't matter, but I couldn't pass up the $5.00/gallon PP.
