JB4 and 100LL AVGas

hcopeland · 06-18-2018, 02:10 PM

Hey everybody,

So I’m kinda interested in running 100Ll. Before you strike me down where I live the closest e85 is 45min away and I can only get shitty California 91 at the pump. That being said I know some of the potential risks with O2 sensors but what I really want to know is if I throw the JB4 in map 5 would it accept it? It’s much easier for me to get 100LL than most other fuels. Has anyone tried this yet?

Don't use any form of leaded fuel as it eats up the o2 sensors. Unleaded race gas, E85 mixtures, or MMT based octane booster all good ways to get the octane up though.
