Just wondering if some of the high-end fuel systems (APS, AAM, phunk's) have any upgraded ability to resist the degradation caused by running a higher percentage of ethanol in fuel? IIRC if they are stainless steel or teflon coated they're good to go... now of course, injectors might be an issue, etc...

i'm just researching the idea since i'm upgrading the fuel system any way. The $ savings would be huge over here as ethanol is about 0.50 Euro per liter and Super100 (95 R+M/2) gasoline is 1.44 Euro per liter.

 

The primary problem is keeping ethanol dry as the moisture it absorbs is what reacts with components === rust and corrosion for metals and creating acids with polymers/rubber.

In EU you will need to mix gasoline in cool weather [below 50F] to enable the vehicle to start and warm up.

Reprogramming ecu to work with the lower AF ratio is often a challenge not to mention the 40% increased consumption per mile with 95% ethanol.

Why hasn't the government raised/applied the same taxes to ethanol?
