I've used it twice and it worked well both times. I'd gotten water in my diesel and it froze up the fuel lines - I think before the water sensor because the water light didn't come on.
911 is not a regular fuel additive like normal Power Serve, it's an emergency product if your diesel wont' start or stay running from frozen or jelled fuel.
I poured a bottle (32 oz) in my fuel tank and had someone else take me to work. The truck had started that morning, but died less than a half mile from home. It ran that far on the fuel in they system. It would start again by refilling the fuel filter from the fuel tank in the bed of the truck, but then die again shortly each time. Came back sometime after lunch and the 911 had worked its way through my fuel system and the truck started.
It's also supposed to work just as well for jelled fuel, but I know my fuel wasn't jelled as it was about 10 degrees and #1 fuel treated with Power Serve in the white bottles. The fuel from the tank in the bed would pump just fine.
I always carry two of red 911 bottles in my truck.
