Diesel 911 is a winter emergency use product. This Winter Rescue Formula reliquefies gelled fuel and de-ices frozen fuel-filters to restore the flow of diesel fuel to an engine. Diesel 911 does not prevent fuel gelling – use Diesel Fuel Supplement +Cetane Boost (in the white bottle) as a preventive measure to keep fuel from gelling. Diesel 911 and Diesel Fuel Supplement +Cetane Boost are compatible in diesel fuel and may be used at the same time.

Customer Reviews
Wife only used Toureg for 1/2 a tank since summer and tractor had summer diesel too. Had problems. Topped them both up with winter diesel and added Howes and changed fuel filters. ……Was still having problems with as the summer diesel doesn’t mix well with the winter diesel, and I had found water from condensation in both that froze or gelled. I added it to both. Problem solved for both almost right away. I am now a loyal customer.
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.

About Biodiesel and Biodiesel Blends

As pressure increases to lessen America’s dependence on fossil fuels, biodiesel will become more widely used as a blended component of diesel fuel. Some states have mandated that all diesel fuels contain varying percentages of biodiesel, and the U.S. government has authorized a B20 fuel (20% biodiesel and 80% diesel fuel) for use in non-strategic applications. Poor cold weather performance, high water content and microbial infestation will require biodiesel fuels to be treated for reliable performance. All Power Service diesel additives are effective in treating biodiesel and biodiesel blends and have directions for their use printed on the back of the containers.
