Manual says 5W-20 is recommended. Can I use 5W-30 Synthetic?
Yes you can, but here is no reason to. Early results show Mobil 1 0W20 to be pretty incredible ... very low wear in UOAs. The other (dino) 5W20s from Pennzoil and others have shown very low wear as well ... due to a higher base oil and/or a very stout additive package (extra moly and/or boron). --- Bror Jace
