I've been running 2stroke oil through the fuel every other tank. I've talked to a few guys including my boss who drives a 2016 Cummins Ram. They all say I'm wasting my time and newer engines are designed to run on ulsd without any issues in the long run.


I put in roughly 16oz of walmart outboard for every 20gallons pumped. I know it isn't going to hurt the engine or injectors, quite the opposite in fact.

I'm just curious to see what everyone else is running through their tanks.

I've been running Schaeffer soy shield. Have also ran full torque by le. Both are awesome products. Those are the only two I've tried. Used to run 2 stroke in my 7.3, but I think there's better, purpose built products for fuel treatment.

They sell it for fuel and crank case additive. Kinda expensive but it has results. Over a period of time.

I thought the stiction issue was to do with heui injection systems on the oil side? Do these trucks have issues with sticky injectors?

The older ones do. Not so much the 6.7. But it helps all around tho

Full Torque and Stanadyne look really good. But damn it is hard to argue with the price and amount of gallons treated with Power Service.

I'll have to give them all a decent test run and see what happens.

full torque hands down is best in the 6.7.. I gain 1.5-2 mpg over anything I have tried.. always used power service in my 7.3s. tried it along with howes and the full torque is better all around.. less smoke, better response, smother sounding injectors and mpg gain...
