Wondered what would happen if I used 100% used motor oil(UMO) as fuel. I was done to 2 inches of fuel in the tank(by the way, don't park on hills). That was about 75% UMO. So went ahead and added about 35 gallons of oil, leaving myself enough room to thin it with gas or diesel if it wouldn't run right.
So took it out for about a 10 mile drive. If I didn't know the truck, I wouldn't have noticed anything. Temps on the pyro were 25-50 degrees down. Power was about the same. Engine runs little quieter. I plan to drive to work tomorrow, about 20 miles, and see what happens. If it runs the same, I plan to keep running straight UMO.
I've tried this other trick before. Turn off the master switch(runs fuel pump) while driving, and see if there is any power loss. Figured this would tell me if the oil was too thick for the injector pump to pull from the tank. Before there was no difference in power, 5th gear at 2500rpm. With the oil in the tank it was the same, ran about a mile with the fuel pump off, and the pyro temp's didn't drop, or power.
Did I mention I hate buying diesel?
