Check Engine Light With E85

Neil · 2007-12-23T02:06:13+00:00

I have 2003 Dodge Caravan SE, which takes E85 (has the E85 sticker on the gas cap door), but I've never used it before. The other day my tank was half full, and I filled it up with E85. A couple dozen miles later my check engine light went on. It stayed on for a couple of days. Today the check engine light didn't go on; but it's also much colder today than it's been the past couple of days, so I don't know if that has anything to do with it.So I was wondering if anyone has heard of any problems using E85, such as might cause the check engine light to come on, or otherwise. (The car actually seems to ride a little smoother; but that could just be my imagination.) I need to get my state inspection sticker next month, and I certainly don't want any problems with the check engine light right when I have to do my inspection.Thanks!Neil

I had a similar issue with my flex fuel 2016 Dodge Grand Caravan. I used E8

5 in the winter and it got difficult to start. I switched back to regular a nd no further problems. The check engine light did not come on in my case. I decided it usually wasn't worth the lower cost of E85 because I lost abou t 30% mileage.
