hay larry we have just run some tests here in australia on some CAT 789, 793, dump trucks . i had a chance to talk with the cheif chemist about the pro's and con's of mixing ethanol with diesel. the mining company's are trying the mix purely for emissions and to look politicaly correct!! the chemist has done research on petrol {gas your country} engines as well and while they do burn cleaner i dont think they were any better on economy , another thing was once you run one a blended fuel you should stay on it as the gaskets swell a little more with the water content in the blended fuel if you switch back they shrink back causing leaks. i take it your E85 fuel is 15 percent ethanol 85 gasoline??? was dragster you bought alcohol for a inline deal??
