Owasso, OK

I ordered my truck new and the first tank I did not use the power service additive but and after doing some research on diesel fuel and additives which included calling Ram and Cummins they did both say that it would help and would not void the warranty so I decided to give it a try. I added 12oz to 32 gallons and I have to say it did help with start ups. fuel economy and throttle response. I did not want to jump to a conclusion so 3rd tank no additive and I could tell right away. The 4th tank I added 20oz to 32 gallons and wow it is like a different truck. I can tell it is burning clean and don’t even have any diesel soot in my exhaust pipe which still looks new. I am getting about 21mpg on the highway and averaging about 18mpg. I get about 1-2 mpg better with the Power Service silver bottle. I would guess it is worth the money with the extra mpg’s but to me it is worth it just for how much better the truck runs. I did buy the winter version but have not tested yet.
