2000 Saturn SL, 105,000. Going to stick with 5w-30 Mobil Clean 5000/Mobil 1 EP filter again until right before it gets subzero. Then for winter I'll use my Castrol Edge 5w-30 that I got on rebate today for around 12 bucks for 5 quarts!!!
For some reason, my Saturn's motor really loves this MC 5000. For the first time, I had zero oil usage (down from using 6 ounces per 3K with Formula Shell/Pennzoil).
MC 5000 impresses me, especially for its price.
