Q: Why does anyone NEED dual fuel tanks?
A: I have dual fuel tanks because I can’t carry a refinery in my truck.
Yeah, when you get 13 MPG around town and maybe 16 on the highway the gas stops aren’t far apart even with two tanks. I would like something more fuel efficient but I only drive about 3000 miles a year in my pickup so I can’t very well buy something newer even if I had the money.
