all the gas sold in wyoming is 10%ethanol. its cheaper because the gas tax is lower on gasahol. problem about wyoming is that they are allowed to use the ethanol to bump up the octane to the mins. wyoming probably has the worst gas in the US. they sell 85, 87, and 91 here. i dont run the 85 at all(will knock on any engine). and the 87 octane here is lower octane that is boosted by ethanol to 87 so its pretty crappy stuff. its very common here for cars to run 10-15% worse fuel economy than normal because of the crappy gas(not to mention being at 6000 feet). however ive noticed that the premium here is pretty good stuff. at least there the ethanol keeps things a but cleaner and has enough base octane to run most engines. but i know more than a few older VWs in this reigon that the owners will run 100LL avaition gas when they can find it(100LL is designed for piston engine aircraft its 100 octane with a little lead seems to work well on some VWs that were designed for leaded gas - not to mention the similarities of the VW engine to piston aircraft engines) __________________________________________________ Do You Yahoo!?
