After 3,300 miles on previous oil change:
2 quarts of Castrol Syntec Blend 5W-30
2 quarts of Pennzoil 5W-30
1 pint of MMO
Mobil M1-110 filter (oversized)
08 Jeep Liberty- Edge SM formula 0W20 and a M1 filter. The oil I drained today will be used as top up oil in my Aerostar. The used filter will be reused on the Aerostar next time I change the oil.
After a year of Toyota 0w-20 synthetic, I went back to Mobil1 5w-30.
Running like a top. 85k miles. Used it at the beginning, then tried Kendall GT1, then GC Castrol until it ran dry, then Royal Purple, now back to square one.
I initially and continually ran 5w-20 as it seemed Scion changed the 2AZFE motor to 5w-20, but it was cleared up by an email from Toyota and I'm back n the 5w-30 again.
Using a Mobil1 oil filter as I got a deal on the package, but had been using the PureOne. Gotta mix things up I s'pose
