I read a lot on the internet about the good and the bad of octane boosters.

All I can say is that it worked for me. I have a Honda 750 with very small low speed carburetor jets. 104 definitely gives each tank of gas the extra kick I need for the lower end of the gears.

It was hard to find out just how much this improves the octane rating compared to other boosters, but I did. After making a call to the manufacturer I was told that it will boost the rating by 1-2 octane levels. So if you needed 93 octane for your car and the gas station was only selling 91 you may or may not get to 93. When I asked why it was not a definitive number like 2 versus 1-2 they send it "depends". Their big sell is on the additives that are supposed to clean the engine, but then that is not a true octane booster.

For every 10 points that an octane booster advertises the octane level is increased by 1. No where could I find a claim on the bottle regarding the points so that is why I called. There are octane boosters out there that do specify how many points on the bottle so you know what to expect and can count on...this just isn't one of them.

I have two motorcycles. Over time I found out that the gasoline I put into my fuel tanks makes a big difference. Each motorcycle's owner's manual advises using good gasoline and a high octane rating. I tried several octane boosters and I like this product. I put Shell 93 and about one once of 104 for each gallon of gasoline. Both motorcycles run very good with this combination.

I choose rating because the Boost was simply that: A BOOST.
I liked that it did exactly what its name implied.
I have recommended it to all my friends.

Some people say this stuff does not work...but I don't think they realize what this is for! MOST cars wont need this. If your car isn't tuned for a higher octane rating then this stuff won't do anything for you. For example if your car is set to run on 87 or 89 octane and you fill up with 91 octane you don't gain ANY extra performance.

I have an engine from Japan that is tuned for 94 octane but I live in California where we only have 91 octane and 100 Octane ($8-$9 per gallon for 100 octane) at certain locations. So I have been looking for alternatives and THIS IS IT!

After using about half the container per 6 gallons I have noticed much better torque and my car is able to hold boost from my turbo charged engine all the way to 7k RPMS, where as before the boost would plateau at around 4500 RPM!

I was skeptical at first but for right now this is the best alternative for me.

I'm running 10.4 to 1 compression on an old 1967 muscle car, and 93 octane is not enough, so I get a little pinging sometimes (detonation). When I run 104 Octane, it reduces the pinging, so it has helped in my situation.

If you don't need the octane, then wouldn't waste your money on any of these products. The only way that you can get more power is if it allows you to run a hotter tune (like a 94 octane Japanese import or a turbocharged car), then it could help you run more advance without damaging your engine, but only if your engine is designed to handle the higher octane. Most consumers should be fine with regular pump gas.

This is a good product for those that need it, but it's not horsepower in a bottle. Think of it as detonation insurance. Torco Accelerator is another product that works.
