I thought that brass was one of the metals affected by Ethanol. I may be wrong though, having a senior moment.

McCabe-Thiele (Ted):
Can't see Alcohol attacking Brass though there is something called the Olygodymanic effect with surface ions.

Although ethanol has been known to gum up and cause clogging in fuel injectors and fuel filters, the corrosion problem is typically limited to carbureted engines, according to Scott Diehl, National Sales Manager at Driven Racing Oil.

“Ethanol in a modern fuel-injected vehicle is typically not a problem,” he said. “The components used in these engines are more compatible, but carburetors are typically made from alloys that are more susceptible to corrosion–zinc, aluminum, and brass.”

According to Ed Callis, V.P., Technology at Red Line Synthetic Oil, other components are at risk, too.

“Fuel hoses, O-rings, seals commonly installed in older engines and fuel systems are negatively affected by ethanol,” Callis said. “Leakage can result, so these components should be changed out with ethanol-resistant components.”

Dunno, the owner of the Toyota workshop I get my trusty '96 Carina E serviced, told me about a BOSCH seminar he attended, showing the results due to Ethanol content after (simulated) 400,000km on a Diesel injector...
The outer casing looked like melted, forming an "icicle" pointing into the combustion chamber...

Most/many petrol engine are not direct injection generally, and so dont have the injectors exposed to pure combustion.  Does diesel have ethanol in it there?
