In Reply to: Any opinions on "octane boost" formulas out there? posted by John D. on March 02, 2001 at 08:12:20:

Karl is right that octane boosters give you 0.1 to 1 point higher per tank and most are actually less than 0.5 points. The best booster is NOS "Race" formula w/ about 0.8 or so, but costs $10 a bottle. However, it made most economic sense to buy 103 octane race gas at $4.50/gal and mix it 20/80 w/ 92 octane to get 94 octane.
