soooo im away from my car right now and my brother in law is driving it for the summer. he owns a couple gas stations in las vegas and through the grape vine i heard that as a birthday gift, he's gonna convert my car into an e85 running pony. now, i dont know anything about e85 conversion but i do know that its slower burning and a lot cheaper than 91 octane. should i be concerened about anything??? or should i be happy to go green(so to speak)?
