"Been running E85 in a 4G63 for 12 years plus. I cycle between periods of 91 & E85. The reason for the high carbon deposits on a E85 motor is that E85 is lacking, in percentage, the PIB cleaning solution found in regular high octane gas (PIB = Polyisobutylene). Injector gunk is very common on E85 run motors due to the low percentage of PIB. Learned this from a petroleum engineer."
Definitely noticed increased deposits in my E85 cars. Am i the only one?
