If you only save 30% on a fill up, then you are still not saving any money with the extra ethanol needed to run proper air/fuel ratios.@kneedragger85: true, if he wants to run some blend. Here in Europe, running ethanol at stock level saves about 30% on fueling costs..
Rubber cracking is a myth for cars built after 70's/80's: ethanol will clean the gum in the hose, if it's already cracked it will have a leak because dirt won't fill the crack any more. That is the same debate than the one about mineral and synthetic oils on old cars.
You are contradicting yourself now....First it cleans the goo, now it accelerates it. Please stop.@airhead04: rubber goo was here before E85. The engine compartment fuel hose are rubber and need replacement after years, but that's true, e85 accelerates the "wear"
