My average is 1 ½ gallons to 2 gallons a month. I have used as much as 2 gallons in a little over a week. I went through ½ gallons today. When I go to the track I normally do about ½ gallon a day. Today I was just bashing my Savage for the first time in about 5 months. Normally I only race. I buy fuel by the case as I get it cheaper that way.
