holeshot engineering love's uneducated people who always think "more is better" when it comes to octane..
cracks me up when I see people dumping 5 gallons into their stock motored car.. i've tried to warn them, got nothing but dirty looks and, "what do you know, you drive a ford" comments from a few import owners.
remember MON and RON ratings are a little different.
I try to use VP Racing fuel mainly (running c-12 or c-16) great stuff, have to buy it in bulk to save $$$ though and they use MON numbers..
also, you guys haven't even touched on some of the fuels or additives that are out there that have an increased oxygen content (i think that is right).. costing upwards of 30-40 a gallon..
crazy what people will do to win...
