Scrounger,
I stop at a place that is about 20 miles from my place to buy the off road diesel fuel. I usually get 20 gallons per visit, and try to make the stop when I am in the area anyway.
I think the price difference is about 40 to 50 cents per gallon, but that is not the motivation for me. The place that I get the fuel turns over enough that it is always good quality and water free. They also fill school buses and other government vehicles in the area, which frankly surprised me when I saw it the first time...off road fuel in on road vehicles???? Seems to be so, at least in that area.
The one time I bought on road fuel from a different place I was shocked to see a fair amount of water in the quart jug I was using at the time to check for water. What I was doing was taking the last quart of fuel out of the fuel can, and putting it in a glass jar, and letting the water settle out. I found a surprising amount of water in the one five gallon of on road fuel I bought closer to home, but never even a drop in the off road fuel I get from the place I mentioned.
If you ask around you may find a source of off road that sells in small quantities. It may not be a one call, let your fingers do the walking type experience, but I bet you can find a place. After you do, one place is all you need if they proviced quality fuel like the one I found does.
Happy hunting! /forums/images/graemlins/grin.gif
