Used StaBil in the past when I wintered the MH. but with the added booze in the tank now days I have heard too many stories of StaBil not doing the job,, I do notice they now have an "Ethanol" formula.
When I calculated the amount of driving I'm doing this winter, and the amount of gas in the tank.. I added 2 cans of Seafoam... That should hole me till I gas up come spring.. NOTE: I"m full timing but I average around 12.5 Miles a week.. all 30 minute trips.. Just not that many of 'em. Now that my motorhome adopted a 2001 Dodge Neon Puppy.
