<www.jegs.com/i/Race-Gas/814/100032/10002/-1?parentProductId=3410293#moreDetails>This even appears to be a street legal concoction. 49 maybe 50 state.If you care.Anyway, scroll down to "click here for blending guide", the base octane numbers are 87,91,92,93.Standard USA R+M/2 pump numbers.Which would lead one to believe that the claimed octane increase is quite something, compared to the crap hawked since the late '70's that never seemed to work.(104, etc). 2 oz. per gallon added to 93 R+M/2 gives a pump number of 97.In my experience of blending fuels, this should work for most stock, 9:1, Brit twins, set at the factory engineered/specified timing.If not,don't be cheap about it, one more oz./gallon should put you over the top.I live at about 1,000ft above sea level.I wish there was a product review forum at Britbike.If the people speak, and spend money,maybe we will have better quality stuff available. A WIN/WIN No?

have not tried this brand but have used every other one on the market all were a waste of money even the stuff that's supposed to be tetraethyl lead. My best results are Sunoco 110 leaded race gas mixed with ethanol free pump gas .I mix 1 gallon 110 to 3 gallon of the ethanol free and have excellent results no valve ping even on a grade in high gear.

I too have never tried the above additive but had no luck with the brands that frequent todays auto parts stores. However I agree with Tri, that 110 leaded racing fuel mixed 1 to 3 with 93 octane ethanol laced fuel makes a BSA twin purr.

Since the late 70's my brothers (3) and I would bring jerry cans to the local airport for 100/130 (green) and then 100LL (blue) fuel to mix, to run our high octane, stock,-GM/Mopar/Britbikes-machines.I did find at one point, a fuel additive with tetra-ethyl lead that really worked and was legal for the street for pre '75 machines.At the time.But that too disappeared.It must be kept in mind, that regarding the physical laws and fuel additives,all seem to have a very big diminishing return factor.I am very interested to hear any feedback on this product.The autopart store stuff is $#!T,and I often wonder, as with many things, if money was put into research and development and truth, instead of promotion & advertising, if it wouldn't be a better world.In my experience, any fuel additive heavily hawked commercially does not perform as advertised.

Curious:

How long do these 'blends' keep? We all know about the shelf life of the modern crap, how long can a 5 gallon can of, say, Sunoco 110/93 ethanol-free sit?

Cheers,
