This was before the emissions rules kick in here on the fuels in the U.S., the new eco friendly fuels, gas and diesel fuels both, with alcohol in them suck big time on power and economy on MPG down
I switched back to gasoline and loved it after that.
I've been told that 95 % of the vehicles in Europe are diesel fuel powered and get way better mileage than the vehicles they export to us here in the U.S. whiney Their big diesel powered V.W. SUV get 55+ MPG in Europe work We need to be able to import them and make American vehicle makers catch up on making our vehicles clean and efficient as there's are twocents


Or they should make propane and natural gas really cheap per volume and then we can turbocharge the snot out of things with it, they both have pretty healthy octane numbers.
