Joe

Completely blown away. I had a Water In Fuel message pop up. I drained the separator 3 times. Continued to get the message. I saw no water in what I drained. Truck was now in limp mode. Took it to the dealer after being stranded for 4 days(I’m a hotshot hauler) at a truckstop because of a holiday. Dealer said there was water in the fuel. I asked to see this water. There wasn’t any. That’s just what the computer was telling them. Found out there was a Ford service bulletin stating some biodiesel can get moisture levels that are not regulated. The remedy was a $700 system flush and refill. Plus the cost of the dumped fuel and new fuel. I was at a loss. A friend had just been talking about 911. They let me run down to the store. I put this product in, shook the truck, started it, no lights or messages. It dissolved the moisture immediately. I mean as soon as it hit the tank. Been driving for 300 miles so far with no issues. I’m a bottle carrying believer now.

Shuttling a tractor from WI to NE over the weekend of January 6 2018 when temps dropped to -15…near Dubuque IA the fuel filter gelled up and lost power…3 hours later I was able to obtain a bottle of 911…I added it to a 100 gallon tank and idled…just over an hour later the fuel filter dropped from 20 lbs to 12 lbs….I was able to continue and finish my trip….filter got down to 3 lbs and remained there

Diesel 911 has worked great for me every winter. I add it to my tank in my RV and let it run for 10 minutes and every spring it starts right up with no gel problems.

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 have been using Power Service products in my cummins Engines for the last 8 years. This product works great. If you gel up, the Emergency 911 formula works miracles literally. The silver bottle adds around 2 miles per gallon to my economy when I use it consistently. The idle is much smoother. I would and do recommend these products to all my family and friends that run diesels. And if you live in sub zero climates, always have the 911 with you.

Voice of the Customer

“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…”
