seafoam cuts out the 2 additive mix.
stabilizes and cleans for less money too.
I run a can every other fill up, 28 gal tank. 2 cans once a yr. to blow out any carbon build up (in 1/4 tank).
I also run it in the 14 5.0 ford, 14 kubota 100hp tractor, all my yard equip.
works great and wal mart is less than 7.00 a can.
