Hope you mean 100LL not jet a or you're mixing gas for a turbine.

The best way is to find toluene. It has been used as an octane booster for many years. It was used in fighter planes during WW2. There are charts all over the internet on expected octane vs mix ratios. The only problem with it is that you have to find a supplier who is willing to sell it to you in bulk. It is way too expensive by the gallon can. The mix ratios go to about 30% if I remember correctly but it really does increase octane by a significant amount. It is as close as you can get to racing fuel. Some of the octane boosters available actually work, but most are crap. When it comes to a high dollar, super heavily loaded boat engine, I would be very careful about what fuel I'm running if there was even a slight concern about detonation. 100LL would be my second choice, but I have heard of some lead fouling problems in automotive applications. I would think that it should fare well in a boat. In any case, I don't know what you're doing with your boat, but if it's strictly recreational, turn down the boost and run gas from the station (except for the occasional shot of race gas and thrill of course).

I live in the same town as Torco if you need some help getting the fuel.

Where in Jersey are you? There are enough of us on the board that we could steer you to all the high octane gas docks in the state.

I get 93 octane right at our marina here in NJ, it's the only one that sells 93 that I know of up here!

Where are you?

We have also had real good luck using the 5 gallon Torco leaded additive,plugs look great .

When added to 190 gallons or so of 93 octane , it makes a batch of approx 99 octane fuel per the above ratio.

But be very care-full , when splashed it will instantly stain your gel coat and upholstery , it's extremely toxic liquid you should wear a mask and you definitely need to use gloves and a monster size funnel.

This season we pulled some boost out of our rigs to avoid the above hassle, if we couldn't get 93 at our Marina we would still be using it , it works!

I was always told that If the octane additive can be packaged in a plastic container your wasting your $ it's junk!
