WRX & E85

I personally wouldn't do it for several reasons. I don't think Subaru will honor any warranty claims related to emmissions or engine problems. You can try if you want. Isn't there a 'list' of vehicles on the market approved for it?

Subaru is not on the list;

Sure it can be done, but you should know the possible problems that may arise. Aside from potential performance issues with a vehicle not designed to run ethanol, the biggest problem with E85 is that ethanol is very hygroscopic, meaning that it can absorb large quantities of water. The potential for water in the fuel can cause real problems with corrosion of the internal parts of the fuel delivery and intake manifold. Most flexible fuel vehicles will more liberally use stainless steel to address this issue. If you were in a pinch, you could probably get away with using E85, but on a consistent basis you are bound to have problems particulary if the vehicle is newer where warranties would apply.

Thanks ... just curious...

I find that if I cruise steady state 55-57 MPH I can get 27 - 31 MPG

Glad there were no serious injuries. Too bad about your ride though. Hope it gets repaired soon!

I personally didn't buy an STi for the warranty...

Did you buy it to run E85? How's that workin for ya?

inquiring minds want to know.

there's only one public station in Kalifornia and its 200 miles away. so, still unknown, but I'm looking forward to trying it. maybe cut it with xylene.
