Quote: it just hit $2.60 in michigan here, and im starting to debate on just filling up with 89 or 87 and just adding a bottle of octane boost , id be a hell of a lot cheaper.
You must have hell of a lot cheaper octane booster than we got around here.
If you pumped 13 gallons into your SVT you'd save anywhere from $2.08 to $2.60 by pumping regular versus premium.
Even if octane booster was free, which it isn't of course, you'd only be saving like $2.50 by using it -- an average of about $10/month. I dunno if I'd call that "a hell of a lot cheaper". And that's if the booster didn't cost a dime.
