I've never heard of either of those gas additives, maybe someone else can provide you some feedback on them. The link seems to work fine for me but you can just put Ethanol-free gas stations in the U.S. and Canada into your browser to get there.
OK....I didn't realize the forum software would turn that into another link so try www . pure-gas . org(all run together:0)
Thanks Dj I found a station that handles the gas about 40 miles from the house, I think I'll just run the additive.
Looks like I did a double post don't know how that happened I don't recall hitting the submit button twice. Mods if you would be so kind you can delete the extra post sorry.
