E85

oma3710 · 08-23-2019, 11:20 AM

I accidentally pumped 6 gallons of E85. I usually only pump 3.5 gallons with no issues. Could I mess something up due to this?

Are you PWG(2012-2013) or EWG(2014+)? If PWG then it may work well and you'll want to log. If EWG, then just run it but don't floor the gas then keep adding premium gas back in up to the 3 gal's that you need.

Do not drive the aggressively and you will be fine.

How many gallons can I safely run alongside 93 on EWG? 3-5 gallons?

Depends on your map, check with your tuner

with the bm3 E30 map you can safely run 4.25 gals of E85 with 11.75 gals of 93 octane to give you a true E30 blend if you have a strong HPFP. At 6 and 10 respectively, you are at an E38 blend. Just drive conservatively until you burn an 1/8 of a tank and top off with 93.

What gas are you mixing it with and what tune/map are you running?

I believe his calculations above assume you are mixing E85 that contains 85% ethanol with 93 that contains 10% ethanol, and you fill completely to 16 gallons total with nothing else.

Unless you have an ethanol sensor you dont really know what %E you are getting from the pump... I know my local E85 station states 55-83% on the pump for E85. I run it in my 3000gt because i just have the tune a bit rich and dont need a precise E content, but don't know if i will ever run a E map in my 335 without an ethanol sensor.
