Roperteacher, I was hoping the opti lube would work, I did measure and add only recommended amount...this is really driving me crazy. I guess I will have to go to the dealer but hate to tell them about the additives, they might use that as easy way out and not find the problem or if did find a problem, blame the additives for it and I am upside down.

Thanks for the input

Seems to be that some trucks run good on additives and some dont. I dont think anyone has quite figured it out yet. BTW mine has been running great on just 2stroke. (16oz/tank) I cut my ratio down a little.

2 happy, yes, it is weird how some truck respond well and others do not to the additives! Some do really well on the TCW3 and other trucks hate it! LOL Let the dealer take a look and DO NOT tell them about the additives. They won't probably be able to tell anyway.... I doubt you have a real serious problem.

I've tried a number of additives.Could'nt tell a differance of any description in the fuel mileage or how it ran or idled.

I've used about a 1/4 bottle of Howe's meaner or PS per half tank of fuel. Now I'm using the white bottle of PS. MY truck sounds better than ever at about 20K.
