I have no clue why some of our dd15's are set at 1725 and some at 1900. They were set that way when they came from freightliner. I know I don't appreciate following those guys in the hills of southwestern pa! I liked my old 1991 400hp mack that governed out at 2200 rpm!

This my daily driver it has a DD 15 with an 8LL. It shuts down at 1900 rpm. I'm one of the lucky ones most of our other trucks shut down at 1725. Do you know how hard that makes it to shift pulling a hill loaded??

Thanks rumplecat. Better get that radiator fixed so it can live for many more miles!

Thanks 98G. I thought I had read about early failure in some of the multi fuel engines but I didn't think 34k was excessive on any diesel.

I'm looking at a m35a2 with 34,000 on it. How many miles are too many on a multi fuel?
