I see a lot of diesel fuel conditioners out there - Power Service, Lucas, etc. When I drove my Deuce 250 miles home from Selfridge ANG Base in Michigan, I added a quart of Power Service Fuel Conditioner and Injector Cleaner to the fuel, figuring it can't hurt and might help. The next tankful I went with Power Service Diesel Klean, since the label stated it was a more of a fuel system and injector cleaner, while the other product was more of a fuel conditioner and cold weather anti-gell treatment with some cleaning properties.

My question is, do these products provide enough benefits to justify the added cost. At $7.00-$8.00 per quart, which usually treats 100 gallons of fuel, that adds another 7 to 8 cents per gallon to the already high cost of diesel fuel!

Is it worth using these products or am I just throwing money away? At $2.66/gallon, the current price for diesel around here, I'd need to improve my mileage by .3 mpg just to break even. Would I be better off spending the money to just have my injector nozzles cleaned and adjusted? Or are there other benefits to using these products beyond mileage improvement? There seems to be many places selling a an awful lot of these products; why are they so widely used?
