I keep 4 five gallon cans full. When my truck is at 1/2 tank, I put 2 of the cans in, then go fill them up. The longest the gas has ever sat in them is 4 weeks.How are getting your fuel to keep. Today's fuel can go bad in a matter of weeks if not less. What stabilizer are you using?
Moe's Speed Shop said they have 55 gallon drums and gas that are starting to turn in a week or so. That was a while back. Just curious.
