Useless junk. I'm seriously not even kidding. That little bottle of octane is a scam and nothing more. When they say "will raise octane level by 3 points" that doesn't mean that the gas in your tank will go from 87 octane to 91 octane. In all honesty, that'* closer to 3 decimal points, as in. .3 octane, so you go from 87 to 87.3. When they say "108 octane," that refers to the octane in the bottle, not what will be in your tank. If you want higher octane fuel, buy higher octane fuel. Fuel additives are useless.
