my aunt just filled her non flex vehicle with e85, what can/should she do? She had about 2gal in tank and filled it all the way up.

 

hi there I've heard all sorts of story's about ethanol fuel , but I've been running 98 ethanol fuel in my 383 ( stock 906 heads ) i do use upper cylinder lube though . without any problems so far no pinging or anything . the plugs are a nice tan colour . i suppose you could use lucas or Morley's lube or some octane booster . i am no expert though just my 2 Bob's worth , good luck .
