im planning on running e85 in my 7. the things that i know are that i have to run approx 20% richer, e85 is about 110 octane, and regular 2 cycle oil will not mix with e85 very well, is this true? what other things do i have to know and look out for when doing this conversion?

 

Neoprene seals to replace the rubber ones.

 

so ethanol eats rubber?

 

yes it does. other than that and adding extra fuel you should be fine.

 

what about 2 cycle not mixing well with e85? my boss races snowmobiles at the track and he deals alot with ethanol at my work told me that there is a special race 2 cycle oil called "BG" that would mix alot better than standard 2 cycle. anyone heard of this?
