I saw this particular octane boost that said it will raise octane rating from 5-7 numbers, not points. Is this true or do all octane boosters only raise it a little?

The only 'real' octane boosters are xylene and tolulene.

tulene is paint thinner basically.... leaded gas is actually the result of having higher octane, dont ahve the specifics off the top of my head, I'll have to find the article I have at home...

Yup, and there's already some in your gas tank

I've run a half tank of leaded 100 and half unleaded 93 a few times with no problem yet, but I'm guessing it'll take more than that to mess up the O2 sensors.
The 'lead' in gasoline is tetraethyl lead, Pb(CH2CH3)4. When added to gasoline, particles of lead and lead oxide, PbO, are formed during combustion. This causes the gasoline to burn more slowly and smoothly preventing knock and raising the octane rating. 1,2-dibromoethane is also added to the gasoline to remove the lead from the cylinder by converting it to a vapor, PbBr2. This is how the lead gets released into the environment from leaded fuels.EvilMSP said:What raised the octane in old leaded gasoline? I don't wanna just assume it was lead additives alone so i'm asking
Ethanol is often added to gasoline today to boost the octane rating without producing the harmful effects caused by lead being released into the environment.
Thank you for the wonderful answer, and I totally forgot about ethanol. I forget what series it is (perhaps nascar) but the gasoline has such a high % of ethanol (or pure I forget) that it burns clear. I remember seeing a video of a pit crew guy running around flaying his arms and you could only see heat radiating from his body (he was on fire.)
Yes, Indy cars ( including Indy Racing League) use straight methanol fuel instead of gasoline. Methanol (wood alcohol) is similar to Ethanol (grain alcohol, typically made from corn) but it is poisonous to drink. At least with ethanol, if you lose the race you can siphon off some fuel, get drunk and feel better about the loss. (Don't actually try this!)
Methanol is used for two reasons:
1. Being less explosive than gasoline it is safer to handle at the track.
2. Since it is a "cooler" burning fuel with a higher octane rating than gasoline, it permits the use of much higher compression ratios without detonation than are possible with gasoline.
Both Methanol and Ethanol have a lower BTU content than gasoline so alcohol-fueled cars require larger fuel tanks (sometimes twice as large) and have a much higher fuel consumption compared with an equivalent gasoline- powered car.
Alcohol can burn with an invisible, smokeless flame compared with gasoline as you pointed out.
