I've been using Mobil1 10w40 full synthetic, because I'll never drive it when temps are below 14F, I may sometimes drive it when it's below 50, and most often drive it when it's above 50F.
Could someone explain the thought behind using 5w-40 when it's not spec'd in the manual? Obviously since so many people are using it, there must be some reason that I'm missing. School me, please!  |
Yes your right. I guess My Oil preference comes from LN recommendation for the block update they do with nickies. Mobil may not make those blends any longer. except the extra mileage formula.
