Its not the fuel causing the problem.<div>E10 is pretty consistent in chemical composition. Ethanol is Ethanol and its made to a spec. RBOB is made to a spec. Blend the two together and the final product has to meet the spec.</div><div>

Why is it then that some parts of the USA seem to have far more fuel related problems than others? Then some parts of the country rarely report problems on any of the forums.
For example, you rarely hear of problems with fuels coming from the Texas - Oklahoma refiners and sent north via pipeline. Yet problems seem to be very common in Florida and other parts of the SE, Arizona and some parts of the SW and Hawaii.
Fuel is the variable here with engine parts all coming from pretty much the same sources. Nobody ever mentions the chemicals used to denature ethanol but it is used in such a low percentage I doubt that would be a problem. I know producers in this area use different materials depending on the time of year, costs, etc.
