“For years, not only was I opposed to any fuel additive, but was utterly opposed. When anybody asked what additive they should use, I would reply “diesel should be the only thing in your tank.” One day, after trying to battle a fueling issue that left me with white smoke at startup and at high rpm’s, I was desperate and, against what I have always said, picked up a bottle of Tank Cleaner (Clear-Diesel Fuel & Tank Cleaner) and a bottle of silver cetane booster/injector cleaner (Diesel Kleen +Cetane Boost), since in Florida it never gets below 50. Within 50 miles, all my skepticism was gone. No more white smoke AT ALL, easier starting, and even the SOP (seat of the pants) dyno saw increased numbers. I no longer doubt the ability of fuel additive. It saved what could have been thousands of dollars in needless repairs. Thanks, Power Service!”

“I have a 1999 ford 7.3 that is the worst to start up when it’’s cold. I have to leave it plugged in if I’’m going to leave for more than 10 hours cause it will not start EVEN WITH STARTING FLUID!!! My friend told me to try Diesel 911 so today i had no other options. i drained my fuel filter and put 911 in and it started right up. I will start using this stuff all the time in the winter. THANK YOU!”

“I have used Power Service additive for over 10 years in my diesel trucks and tractors that I depend on daily all winter long. The anti-gelling features have proven dependable in the cold North Dakota winters.”

“My dad had started using this product in 1976, So when I got my first diesel pick-up he suggested it again. Me being the hard-headed and cheap teenager I would never listen or spend the money. After I blew 2 injectors and collapsed the fuel filter to a pancake. I tried the product, and just like every teenager I stated to believe the fatherly advice. Now after 10 years I firmly believe it keeps my diesel running as strong as the day it was bought.”

“Power Service has really helped me a lot personally, I rely on my truck for about everything. Living in the south east, Alabama, we don’t really have a lot of freezing temps but here in the latest cold snap, 6 degrees, your winterizing products have helped me tremendously on cold starts. Treating my fuel in an LBZ Duramax with Diesel 911 got me up and running this morning!! I run Diesel Kleen in mine most of the year… Your products are fantastic and I can’t thank y’all enough…”
