up here in the N.E. we get hammered with the E10 winter blend plus the affects cold temps have on fuel economy. My 06 Avalon could lose up to 20% mpg's...... waiting to see how the new venza I4 reacts this winter to the formulation. On a trip fom NH to FL last summer, I got 31 mpg's @ 75 mph ave (which translated to getting there in 2.5 tanks of fuel - a substntial difeence from winter mpgs.
Beyond lost mpg's, E10 has major affects on carbureted engines.... especially motorcycles when they're put into stasis over the winter months or as little as 2-3 weeks during a vacation period.... had to have my carbs rebuilt because of the E10 depisits to the tue of $600. A lot of people are going to the dealerships expecting warranty coverage and are told - "sorry nota warranty problem...it's a fuel problem..." Injection systems ar not immune.....it's expected to show up with long use of E10! And the Fed wants to go to E20????
Acetone has been bantied about as an additive to improve the mpg's with E10 formulation with mixed results reported..... the bigger question is the unknown affect on fuel system components.
Has anyone tried acetone? Results?
