It also seems (maybe coincidence) that the syn. oils stay clean longer....imput please.
Thanks.
Only one my second oil change (first was at the deal for free, so I guess they used Mopar stuff) but I put Rotella-T 15W40 in the engine. I will do so for at least the next oil change, and we'll see how things go. I don't really see the need to spend the coin on full synthetic since I'm gonna change it every 7500 anyway.
I use Valvoline Premium Blue with Fleetguard Stratopore filters. I have purchased it at Cummins shop, NAPA, and Schuks Auto Parts. My first purchase was at Cummins in ND and guy said only a few of his customers there used Extreme and then only in the winter if I recall correctly. ND is a place where it would really make a difference as it does get a bit chilly in the winter.
