I believe the consensus is these products often fall short of claims made by the manufacturer.

However, someone I know who races high HP, high speed ocean race boats would use this when going on poker runs. Suppose to boost Octane rating by 2levels. Anyone familar with this product and being for a marine application any reason it would not work in cars?

Most consumer octane boosters are alcohol and not good for your fuel system. If you actually need higher octane fuel I'd add some proper Sunoco or VP racing fuel. Many race tracks have this available on site these days if not available from a local retailer.

Most claims for Octane boosters, when you read the fine print, state that they will raise the octane by 0.1 number at full dose. This is both insignificant and expensive. This product seems to have zero technical info posted (what I could find from Google). They claim an increase of up to 2 octane numbers, but that could be a smokescreen.

Based on the label, you only need 6ml per gallon of gas. I strongly suspect that it is equally effective with boats, cars and curing cancer.

Isn't this what Ghetto Racer used as a drink mixer??

Would that be two parts Red Bull, one part Valvetech, shaken not stirred?

I will have to get the MSD sheet from the manufacturer. I spoke again with the person who mentioned the product to me. He said that Sterling Marine (a high end boat engine builder) reccomends it and a lot of the racers will run it. These engines are producing 1500 - 1700 HP at the prop.

The black science of additives. Sunday Driver's comments made me laugh out loud though, so thanks for that!
Funny, I recently found myself reading the label of that "Lucas" fuel additive, trying to see what it was really all about.

Many of the general statements on this site about some of the Octane boosters available on the market are correct. However I would like to correct some comments about ValvTect Octane boost. It is a very concentrated MMT based product and contains no alcohol. MMT is technology that is proven effective and documented in many tests world wide. At the dosages recommended on the bottle it can boost Octane up to 2 full numbers (20 points). That means it can raise an 87 to an 89 or an 89 to a 91. Many products say they will raise octane 5 or 10 points. That is 1/10th of a number. 5 octane points turns an 87to an 87.5. ValvTect Octane boost can be used effectively in an automobile application at a maximum dosage of 1 qt to 140 gallons and should not be overtreated in applications with a catalytic converter.

Thanks for adding the info here. I have a few questions...

How was the octane improvement tested?
With an additive, I would assume it changes the burn rate of the fuel. Do you suggest timing changes with your additive?
Is there a HP loss due to changes in burn rate, if no other adjustments are made to the engine?
Are there issues with 10%, or the proposed 15% ethanol content in pump fuels?

It is also a wonderful dessert topping, and can be used to find submerged submarines.

Shimmer! Mmmm.

Valvtect makes good stuff. I used it in my offshore toys but wouldn't put it in a car engine that calls for 91 Octane when both 91 and 93 are readily available on the street and at the track.

Well that's kinda not the point the issue (as I understand it) is would it help guys with higher compression run 93 at $3 a gallon as opposed to race fuel at $10 or some shot in the dark blend of the two.

I use the Powermist octane booster in my 2009 Cup car with great results. My mechanic did test it on a dyno and certify me that I can use it with 94 gaz instead of race fuel. Much cheaper and no race fuel to carry at the track.
