Comming home from a long trip last weekend I hade to stop for gas near the St. Louis metro area. Anyway had to use gas with 10 percent ethenol. My TriGlide does not like that crap at all. Noticeable loss of power on hills and pinging. Slight backfire on decel. I refilled with good gas since then and it seems better. My question is, will bleneded fuel cause damage to my engine? Seems like in the metro areas all stations have blended fuel. Should this be avoided if possible? Thanks
