Maybe the PO didnt understand much about octane, etc. You (and too many others) are not only wasting your hard earned money on higher octane, but can also be damaging your engine with higher octane, just as one can by doing the opposite. It has been estimated Americans spend a few hundred million dollars annually on wasted octane expenditures. Higher octane can give the impression of "higher energy", or "more power", but it actually has less, measures as BTU's.

And more wasted money to the slick auto ads pandering useless elixirs/additives, preying on the avg joe weekend mechanic, and even the pros, accompanied with dubious endorsements/"research" on their concoctions of mostly mineral spirits/naphtha.

The EPA requires ALL grades of gas to contain the same cleaning additives for good engine combustion. Higher octane will not burn cleaner, only slower, reducing pinging, if required.

Lets stand together and tell these crooks where to go, and to find a job their mothers can be proud of.
