Looking for people who have been running E85 and using coated pistons. We lost an engine this weekend. We have been running E85 in it for four years. When we tore it down all the piston skirt coatings had came off the pistons in flakes and clogged the oil rings. Other than that and the resulting damage the engine was in good shape.
So the only thing we have is the engine has always been on E85. The question is has anyone else had an issue like this.
We are not pointing fingers or blame and will be calling the piston manufacture monday. We are just looking to see if anyone else has seen anything like this. the coating came off suddenly and in flakes

I don't use coated pistons, so I cannot give any info on that. I have seen no oil related or unusual wear or problems in my 6 years of using E85. As far as the manufacturer's claim on the coatings, I'm not going to say that E85 didn't cause your problem, but I would expect the manufacturer would point to something other than themselves. Are you experiencing fuel dilution of your oil?
