Tom,
ERC Racing Fuels is the gasoline provider at BUB. According to this chart, http://www.ercracingfuels.com/sxs1.htm, the highest octane is 119. However I don't know if they bring all their fuels to the race. I use the A-8C 116 octane leaded fuel.

I do not know what you mean by "in what rade feks Tank." Can you re-phrase that?

Hi
 i think the a-8c 116 octan will do the job.

Is octane 116 the same in europe and USA ?

there is RON (Research octane number) and MON (Motor octan number)

I wrote wrong about the tank rate, i ment Tank rate.

Thanks Tom

The use of the term differs in Europe, the octane advertised at the pump is the RON number (which is always higher than the MON number).
In the U.S. we use the average of the two number often referred to as R+M/2 .

For example a fuel that has a RON of 110 and a Mon of 87 would be sold as 110 octane fuel in Europe, and would be sold as 98 or 99 octane here in the States.
That is for commercial sales at the pump. Many racing fuels specify which octane number they are reporting.

The MON number is usually more important for racing applications especially turbocharged and blown because that octane number uses a more sever test condition with higher intake air temperatures than the RON test does.
