Did You Know?

Water is dissolved in and carried by all diesel fuels. At temperatures below + 32°F., water that has collected in fuel-filters freezes. This causes decreased fuel flow to the engine and results in reduced engine power or engine shutdown.

I’ve got 510,000 miles on my 2008 GMC Duramax! I’ve ran Power Service faithfully every since buying this truck from my son at 196,950 miles. I run a mixture of Power Service and Dexron automatic transmission fluid! My injectors are all original equipment! I run an Airdog lift pump and my truck runs as good today as when I first bought the truck! My father started using Power Service products in.our John Deere 4020’s in 1970 over 50 years ago and you might say it’s a family tradition!

Voice of the Customer

I own & operate a Rock & Roll Entertainment Company that works the 6-State Region year-around. On New Year’s Eve [12/32107] this year we performed 3 shows for the Make-A-Wish Foundation in Aberdeen, South Dakota. I was fully aware of the local weather forecast “up-there” warning of the likelihood of -18 Fahrenheit temps overnight. We were running one 55 gallon tank which had 15 gallons of “Zero Flow” #2 Premium Diesel, and 37 Gallons of #1 Premium Diesel, along with 12oz of Regular Power Service. I have ran Power Service for decades, and it has never let us down … until the next morning. Because the new forecast was upgraded to have even lower temps [under -30 Fahrenheit] I opted to set the controls on the truck for 1300 R.P.M and let the truck run from 4:00am until 8:30am to insure that we would not have to fight starting the truck in those kind of temps. [the actual temp had dipped to a real -32 without wind-chill factor] The truck ran perfectly until we hit 60mph 3 miles south of Aberdeen when the engine lost power and began “chugging”. I have operated diesels for over 3 decades, and I knew instantly that it was gelling and that it was my fault for not using a stronger mix of #1, and perhaps a few more ounces of Power Service. In our truck, I have always carried a bottle of Power Service “911” in the emergency kit. I was able to keep the truck running @467 R.P.M. by manipulating the throttle; my partner meanwhile took our funnel and the “911” … poured it into the remaining 29 gallons of fuel; within less than 3 minutes … our engine was running perfectly without another “hitch”. We had carried that “911” for over 3 years, have never needed it … until then. I was so impressed that I vowed to tell all of my “Diesel Buddies” and want EVERYONE ELSE to know that Power Service “911” is “The Real Deal”. I will never travel without it after this episode!! Power Service Products are irreplaceable. John McCormick
