Hello car friends! I can only warn all Ford Fiesta drivers! Better fuel NO E1o! I have fuelled with my (newly bought 3 days ago) Ford Fiesta, BJ1998 yesterday E10. Now the engine is running extremely restless, no longer pulls, stutters…!!! If I just didn’t do it! I did ask myself: “..as well as all Ford engines can handle E10…” but it WAS A FEHLER!! After I have fueled now for 20 EUR conventional SUPER it is a bit better, but not like r ok! Has my engine already been damaged? What do I do now? Should I refuel the tank immediately with Super? Super Plus? Or better drive the tank empty before (about 1/4 tank filling)? Or do I break even more with it? HELP!!! Peppermint
