I guess you guys at the auctions need to get locking fuel caps , seems like a cheap investment apposed to 10k. I run used cooking oil in my 84 250 which is the same thing not paying your road tax, but every cop thats ever stop to ask me what I'm doing when I'm fill up on oil is good. Good to see some one getting around this B.S. I say srew their tax. They spend every dime they can get there hands on stupidness and they keep getting greeder.
