Another 100 octane unleaded is T4 made by VP fuels. It contains plenty of MTBE. It contains 0 ethanol. I use it and it works perfectly, but it evaporates like crazy here in South Florida.
Really. Our track states their "hot 101" I think its called uses acetone,toluene,xylene and a splash of MTBE to achieve that octane rating.
Its not actually a branded pump. I think they get the Mohawk/husky 94 octane and blend in those chemicals,then they get it certified by an independent firm to insure it meets the minimum.
In fact it was at that track(smallish city ,don't enforce the cage rule til you get into 10s,no helmets til 13s good ole boys type track)where I first learned about nitrous,octane and timing and how each variable works with the other 2 variables.
From what I absorbed there,and since seen on multiple websites,is that acetone/xylene/toluene all have octane rating above 120,so using any of those products is an actual octane booster,not like those absurd 300mm bottles of alcohol and kerosene.
And a very interesting phenomena occurs when any or all of those products actually reduce the surface tension of gasoline,so when the fuel is introduced to the air stream it becomes vapour faster,which aids in the fuel achieving a complete burn.
Due to this more complete burn carbon deposits are reduced or eliminated and the catalytic converter isn't required to process as many pollutants.
I can say from experience using one or more of these in everything I own that burns gas I have seen a drastic change as far as deposit formation,and a nice bump up in fuel economy.
I've done the math and in my hemi the fuel saved costs more than the gallon of chemical,so after the first tank it has paid for itself,and I can still treat 900 or so more kms. The addition of tc-w3 has shown to me,based on the carbon condition before and after I has led me to believe it has the ability to remove multiple hundreds of thousand of miles,where plain fuel and chemicals fell short.
My concoction works so well the neighbours come to buy pre-mixed quarts,at the modest cost of 10 bucks,to which I get informed it saves the 20 or more,so the initial investment doubles itself in money not spent,with the added bonus of upper cylinder lubrication.
Each quart treats 200 litres of fuel.
