My brother-in-law is a truck driver and recently switched jobs. He gave me allot of Power Service Diesel Fuel Supplement + Cetane Boost as well as Power Service 911. I know there's allot of snake oil out there but does anyone know if this stuff does what it says it does or know of any ill side effects from using it?

I have never read or heard of any negative side effects from Power Service products.

I use the Silver bottle at a ratio of about 8-oz per 20-gallons fuel.

The 9-1-1 is not a preventative, it is just to use IF the fuel has gelled.

I used to use Power Service regularly years ago (White jug). Now I just use it if winter is coming on and I'm stuck with non-winterized fuel in my tanks. With that said, when using it I noticed absolutely no difference in fuel mileage, engine operation, engine noise or whatever. Sure can't do any harm although the fuel injection shop owner our shop used to deal with once told me he thought it was a waste of money.

Years ago at the Chrysler dealership we had an abnormal run on Jeep ZJ fuel pump failures and long story short, the factory claimed it was due to fuel additives either in the gas itself and or possibly customer installed additives that broke down the fuel system components which caused the failures. Thought I'd ask about the Power Service before I tried it. After hearing there isn't any benefit to it, I may just give away the silver and save the red for the cold weather.


Thanks for the replies.

You do realize that 100% of the diesel fuel sold in the US has been additized? Meaning that the very same chemicals found in your Power Service jug and listed on the MSDS have been added at varying quantities by the Bulk Fuel Distributor.

In fact, Exxon's premium diesel is actually additized with Power Service products.

PaWest, if you have a choice, I'd say use the P/S in the white jugs. It's for winterizing your fuel plus cleaning injectors, etc. The red is for supposedly emergency use after your fuel has already jelled. I've read, plus been told when fuel gells and gelling temps are all over the place. I definitely had summer fuel in both tanks and added a few ounces of P/S in the white jug before the real cold hit, and my pickup started one morning at 10° like it was August so maybe the stuff really does keep fuel from gelling.

I never did figure out just how the Power Service 911 helps with a diesel engine with gelled fuel start back up. I know that it will help the fuel in the tank but what about the fuel in the lines, and filters. If there is no fuel flow they are going to stay gelled up no mater what you put into the tank.

Its a catalyst which means a chemical reaction is actually taking place from molecule to molecule. Even though the fuel appears to be in one position only, the atoms are still active.

Does it reach all the way up to the fuel bowl? I have never had to use it so I can't say certainty but 30 years ago I would add Kerosene and it would accomplish the same thing.

Yessir, you're welcome.

My thoughts exactly, Bugman.:laugh2: During one of our more severe winters, there was a 2 axle box truck pulled over just out of town on the highway that had tarps all around the lower cab and lower body to ground with portable gas powered heaters blasting heat under the tarps. I'd bet they put every anti-gel additive known to man in the tanks but it still took 2 1/2 days for them to get it unthawed and running.

I have built many of temporary framework/tarp structures around various equipment myself. In fact, it was the only way to start our equipment every day of the the long arctic winters. We ran straight #1.

The heat from the torpedo heaters also helped cut down on the number of hydraulic lines we would blow.

I did the same thing when I was working in the oil fields of north eastern Utah back in the 70's. It was only a -45 when the fuel gelled. We needed the truck asap so we built a nice tent and built a campfire under it. We didn't have any propane heaters in those days. 2 days later the truck fired up.

OK. After some research it appears 9-1-1 actually works as a water dispersant and controls water. So it is not acting on the physical fuel waxing as much as it acts on the water in the fuel which ices.

The fuel supplements such as Power Service White jug will lower the temperature at which the fuel gels, gelling is the result of wax (paraffin) particles in the fuel solidifying when exposed to cold temperatures; however, these products do not often contain much water dispersant since water dispersants need large quantities to work. Thats why 9-1-1 is a 16-oz to 20-gallon ratio which is 4x the recommended amount for the white bottle.

Bugman, in answer to your question about how 9-1-1 reaches the fuel bowl when added to the tank, the answer appears to be you need to add it to the fuel bowl directly:

16-OUNCE (PART NO. 8016)
TO DE-ICE FROZEN FUEL-FILTERS: If fuel is liquid in fuel tanks but engine won’t start: Remove fuel-filters and fill with 50% Diesel 911 and 50% diesel fuel. Reinstall fuel-filters. Start engine. Add Power Service Diesel Fuel Supplement +Cetane Boost as directed to prevent fuel gelling.
TO RELIQUEFY GELLED FUEL: Add 16 ounces of Diesel 9•1•1 to each 20 gallons of fuel in the tanks. Remove fuel-filters and fill with 50% Diesel 9•1•1 and 50% diesel fuel. Reinstall fuel-filters. Start engine. Let engine idle to warm up fuel system. Add Power Service Diesel Fuel Supplement +Cetane Boost as directed to prevent fuel gelling.

I certainly think the additive makes my truck idle smoother. I've used power service in the silver bottle, and now i run red line diesel catalyst in each tank 2 ounces per 10 gallons. If i dont add it for 2 fill ups, then next time i add it and fill up with it, its immediately noticed how much smoother the idle is. I dont see any measurable gain with fuel ecconomy. I drive my truck 2,000+ miles per month too.

My truck actually idles pretty smooth but every once in a while I feel a little roughness after it's warmed up and I come to a stop. Feels a little like a plug wire going bad in a gasser. My truck has allot of time off unless I'm going back and forth from Pa. to Arizona. I'm leaving Pa. May 11th for the 2500 mile haul so I'll try the PS and see if there's any difference.

Be sure to bear in mind the power of suggestion, as a wise former member here once said, "some guys could put blue M&M's in their ash tray and swear their truck ran better". :lol:
Or posted the other day on "the other" site,
"I have noticed that after the motor gets about 2000 miles (after an oil change), on it the average fuel mileage drops. At the point I change the oil it has lost, on the average, 2.5 MPG. I change the oil and it goes back up on the next tank."
