I agree the information being out there is half of the battle. I think if I had one of these 15k and up engines that were all jetted just right for real fuel would be a concern. Once you accidently or otherwise added mixed fuel your jetting could be 10% off lean. Being aware of the issue hopefully would help in setting up proper A/F ratios.

The other issue that no one has addressed is ethanol vs. methanol. It would appear that at least according to Edelbrock methanol is more a serious problem. They site "rapid failure of seals, gaskets, diaphragms and pump plungers." So does anyone know in what parts of the country do mixed fuels contain methanol? It would seems fire from gasket leaks would be the real concern with methanol.
