Looks like glorified E85 to me.
If I understand correctly , and if the vendors can be believed , they use a higher quality base gasoline to start with.
I drive a tanker and when we load , it is ( depending on the season ) 15 % sub grade unleaded , which is around 84 octane , and blend it with straight ethanol.
It sounds like Sunoco and these guys start with a better base grade , which would yield a better fuel.
Straight premium from the refineries that we use is 91 octane and some stations will jack it to 93 octane with 10 % ethanol.
I am not overly concerned with lead , so I considered buying straight ethanol and mixing it with race gas.
But I am toying with the idea of buying a drum of their S and trying it out.
I did find someone local who carries it , and 335.00 a drum is better than a lot of the others.
Their R grade is 425.00 a drum , but not in stock locally.
Switching to straight booze creates another set of circumstances that I am not ready to spend on.
