    EFS Combust - a new fuel additive ???

    Has anybody tried this?
    Www.efscombust.com


    Composition is about 54% ethanol, 36% benzyl alcohol, and the balance a mixture of acetophenone, ethers and a carboxylic acid. Apparently 1 oz in 15 gallons of gas increases power and torque 5%. I found the patent if anybody is interested.

    Sure it does.

    1 fl. oz. = 1/128th of a gallon. So they're claiming a 1:1920 ratio of their product to unknown gasoline will increase power 5% over straight unknown gasoline?

    Think I'll be sticking with an E60 blend and spending my money elsewhere. You would be wise to do the same (at least with the latter).

    I agree there is no octane effect. If there is any effect then it ***may*** have something to do with modifying the properties of the injected fuel mist. Small amounts of stuff can have a big effect on surface properties (like a drop of soap in a pot of greasy dishwater). Just for kicks I ordered a small bottle to test. I'll report back...

    What was your experience with the product? Some Porsche guys in my area all use it on the track.

    I don't think anyone here has tried it yet.
