so my truck has been in and out of the shop.. The fuel pump is going bad. while ******d i had a " reduced engine power" and "low fuel Pressure" warning come on. Filters were clogged with the infamous metal flake. I returned the truck to stock and took it in for repairs. while at the dealership my tech told me that some of the pump whining could have came from my diesel addictive. He claims that the new 15's have a different injector and that we should not be using an addictive with a cetane booster. im new to diesels and i automatically assumed all addictives had a cetane booster in them. Anyone heard of such a thing. By the way the truck only has 14k miles on it. i was using the Diesel Kleen from autozone
