I've heard such bad things about the 15% ethenol. corrosive, rots some plastics and rubber, voids warrantys, etc. I've searched here, and it seems like some think it is ok, some not.

I used to be able to buy no ethenol fuel, but can't find it anymore. it is all 10% ethenol. I figure if 15% is bad, 10% won't be great either.


since we have to buy this, guess it is a moot point, but I'm wondering if it is really so hard on fuel lines, etc.

and if it is so bad for an older vehicle, what to do?

the new fuel lines are designed with the ethanol in mind. I think they wreak havoc on carbs but are okay with fuel injection.

early FI systems have a lot of trouble with EtOH - I know little about what was used in earlier vanagons (and would like to know less) but Bosch CIS has lots of trouble - EFI has less

always use Stabil when storing & don't store until the stns near you switch to a winter gas blend, then run the tank out and fill with fresh, add Stabil and drive around a few miles, then park

It will cause the fuel line to degrade. Even new line unless it is 30r9 fuel line.

If using ethanol is a concern, use an ethanol treatment product:
