Ratio of E85 and 98

recce · 09-27-2013, 03:36 AM

Hi all,

Just wondering what will be the best ratio mix on the two type of fuel? 50:50? Read on US forum its 50:50.

Depends on what you're tuned for as well as fuel system mods. You can probably get up to 50:50 on a healthy stock fuel system. Some cars might not be able to flow that much fuel. Generally if you want to go for higher concentrations you'll need an upgraded LPFP.

But basically you need to be tuned for that particular E85 mix and just stick with that. If you're tuned for a higher % but have less then that's no good and could result in damage to the engine depending on the difference.
