my dad ran a tank of farm fuel today in his 2002 7.3, which had been getting a miserable 14 mpg mixed driving! today he ran farm fuel and it checked a legitamate 22 MPG, mostly highway running 70-75
man even i get better milage running off road fuel. id say 2-4mpg gain? all though i never do of course because thats illagle. hahah forget the stupid fuel laws when its 4$ or more a gallon.

i got a 300 gallon tank i am going to go fill with off road... and i am gonna run it... screw it if you get better mpgs and it is a bit cheaper... i will run the risk... plus around here they do not check for it...
also, to get that big a jump in economy is almost unheard of, i have run the ulsd (15ppm) and changed to 5000 ppm offroad and maybee seen a 3 mpg increase at best. the biggest difference is smoke output, the 5000 is nice for that. if he is getting that big a jump in economy then he needs to change his on road supplier
he has tried K-roger , shell, bp, speedway, and marathon on road. we only buy at high-volume stations so its always fresh too. we have never even seen a water in fuel light.
iv been running 1/2 qt of 2 stroke oil per tank for about 4 fillups now, seems to do a good job at making up for low sulfer fuel. i havent checked my acual fuel millage numbers but it seems to be doing a bit better and it quieted down the engin some. seems like a much better alternitive if you end up having your tanks diped
