Until this year, when the SCCA started making us use racing fuel, I used

93

octane
pump gas with no alcohol, and added cheap 30 weight motor oil. 7 oz. to

5

gallons of fuel, to kill off as much octane as I could. Daryl Drummond

says

we lose 8HP at the top just by using the high octane fuel.

that doesnt sound right.
the higher the octane the harder it is to ignite, so less chance of
detonating,
oil is harder than gas to ignite, you added oil, the gas should be harder
still to ignite
the gas is now even higher octane than it was.
right?

BTW Lynn, why motor oil and not two cycle oil?
