My Kr has a Great Plains 1915 cc VW engine with an Ellison throttle body injector. Great Plains recommends that I use car gas to prevent valve problems. Ellison states that the seals in their units are designed for 100LL only, and that any fuel with alcohol in it will ruin the unit and void the warranty (not to mention create engine problems).
I'm driving a 2003 Mercury Sable with a 3.0 l. V-6. When I use 87 octane regular gas, I average about 26 miles per gallon in highway driving. When I switched to E-10 gasohol, my mileage dropped to 19 with the same driving profile. My next tank of fuel was regular, and the mileage went back up. A second tank of E10 dropped it back down to 19. What would be the best fuel for my VW engine? Opinions? Comments? I thought about writing to Ann Landers, but she probably wouldn't know.
