E10 gasoline

Again, the fuel system (lines, tank, etc) can stand E10 alright as is. It just shouldn't have to!

Be glad it's not a 87 Ford Ranger E10 messed with the computers and I would go from 27 to 23 mpg (15%) on E10. It would also take 2 fill ups before my gas mileage was back to 27 mpg. The E10 also would damage the fuel injectors on this year (I can't remember what other years). This was when I drove it everyday, when it was driven one or twice a week E10 dropped to less than 20mpg.

Their was some research done that show some minor increase in rubber deterioration with E85, now I can't remember what periodical it was in so don't ask (this is the only one I found about increased damage to standard parts, I found several about damage to the engine, but they were very shoddy studies running straight ethanol). In the study they simulated gas cooling and heating like what a car would experience allowing moisture to collect inside the tanks. One of the things mentioned was they don't know how much of the deterioration increase was from the water or from the E85, or the higher rate of decomposition of the fuel. Note these are things cars experiance from sitting.

Were a lot of people are confused about needing to change things over from methanol, that stuff was bad it would eat holes in plastic fuel tanks, hoses, . . . everything would need to be converted.

I don't see why you need to do something make sure you have good fuel lines, use fuel stabilizers if it sits for more than a week. That said I'd complain about it I don't like how it burns in my cars, my cars are not driven everyday so I only get gas once or twice a month. In my current vehicles a 240z and a FJ Cruiser I've documented a greater decrease in MPG especially in the FJ (I don't always add fuel stabilizer to FJ unlike the Z) the longer between fill-ups. I don't mind it to much if I drive a lot but when they sit the E10 causes problems.

Cheers. Before next winter, i'll fill it up with higher octane so it doesnt corrode the lines.
