I've read quite a few different studies that all showed what happens when you put in octane booster that claims to give you 3-4 "points" increase in octane. Yeah, you go from 87 octane to 87.4 octane, and theres your 4 points...lol They proved it all out too, showing that you would have to add several quarts or even gallons to the gas tank in order to gain real points in octane. But the downside is that the fuel is weaker because it's been diluted, and the BTU's have been lowered by having less actual "Fuel".
