I have a 98 Cummins, 24 valve, and have used the Power Service since I bought it, now at 100+K. The Standyne is about triple the cost here.
I can't really figure out what to do as ther rre fleet operators that run a bunch of trucks and do not reccomend anything.
My company runs 13,000 or so class 8 trucks - over a million gallons of diesel a dayr - we don't run a thing for additives. If we thought it saved us anything or actually made a difference in component lifespan, at that scale - we would. We run out trucks to the 700k-1 million mile mark.
FWIW - Granted class 8 is mucho different than your pick-up.
