I've used mmo in my trucks since my first one fuel and crank, rottela and ps too, pisser my trans went in the 90, the 91 I traded for my 01, the 90 had 215k up from 98K when I got it, 91 got at 201k traded at 221k after going to amsoil every where but the crank ( that was dumb, $$$$$) I've had my 01 for a year and a half and almost 20k, it got a lift pump today, might be getting a B.C. VP on monday. cant say that many of us are likely to actually keep a cummins till its dead no matter what we do. if you want to get really depressed look at some of the clunker cars on the road that have no idea what an oil change is the owner just adds more (if that) and they have 200K on them. then theirs us that will spend our last $80 on an oil change cause its time!!
speak your mind SO5.9, some people like other opinions

Hey, Black Ram, how long have you had your AirTex pump? How better is it than the Carter?
On the MMO, if Cummins does not say yes, than I stick with what they say. I like the Valvoline PB, endorsed by Cummins.
