E10 is shortly going to become mandatory for all gasoline in my region.
However, my car specifically says that it is not compatible. There is a big warning in the manual, stating "Gasoline containing up to 5% ethanol may be used. Gasoline containing more than 5% ethanol must not be used as it can causes severe engine and fuel system damage."
I recently checked with the dealer who did a VIN search with the factory, and they confirmed that my car is "unsafe" for use with E10.
They didn't have any useful suggestions, other than perhaps I should buy a newer one.
According to some things I've read, the problem is that the car has aluminum high pressure common rails which can develop pinholes due to corrosion from the ethanol, as well as non-ethanol compatible seals in the fuel pump.
Are there any sensible precautions that can be taken to protect my car?
Replacing the HPFP and common rails basically means taking the whole top of the engine apart (and these are not cheap parts).
