JB4 Question

MiroE90 · 03-02-2012, 12:47 PM

I had a question for you guys that run JB4 Map 1, 2 or even 7 (race map)

Do you guys think its better to run Petro 94 octane (as it still contains ethanol) or is Shell 91 (zero ethanol) better?

I'm really looking for input here especially if you have used both just trying to settle my curiosity, as technically 94octane is better, but is the pure 91 octane better for the engine than the ethanol 94?

If you are running map 1, might as well stick with 91.

Map 2 and map 5 make better use of 94. You can always email terry and ask what he recommends based on a few WOT logs.

I would follow the min recommended octane from BMS for the particular map you are running.
