If you don't mind a little lead, then 100LL at your local airport doesn't have any ethanol.

Most of the fuel systems in cars made since the mid 90's are pretty impervious to alcohol and any water trapped in the fuel increases both milage and energy. During WWII they tried adding water/steam to aviation fuel to increase the range of bombers and it was highly successful but the water vapor corroded the combustion chamber so they dropped it. There are several new ceramic blocks being made that won't have that problem and if put into production could drastically lower the amount of fuel needed by the average driver as much as 20%.
What I can't understand is why when I'm in Europe I see all these cars with diesel engines that make no more sound than gas engines, have comparable power, and get much better milage than gas.GM (and maybe some of the other US car manufacturers) made a bunch of really crappy diesel auto engines. Noisy, nasty, smoky pieces of crap that were maintenance nightmares. GM in particular, converted some gasoline engines to diesels and didn't properly redesign them to be beefy enough to handle the stress. Repairs were frequent and expensive. Performance was bad. They often wouldn't start in cold weather.
While Americans are being pushed into expensive hybreds the Europeans are getting the same milage from a variety of modern diesels which are not even discussed here. And now Chrysler is owned by the largest manufacturer of such engines in Europe, Fiat.
I wouldn't own a hybred if you gave it to me. Originally Posted by theaustinescorts

They are as quiet as gas engines, have the same power, produce less or comparable emissions, and get as good milage as hybreds.
I've been told that it's because of computer control systems that were unavailable before, but would like to know more. Is the diesel available here of the same quality as that sold in Europe. The diesel sold here forever was just one step above motor oil in its quality. In Europe I think the diesel is far more refined somehow, and the newer engines require it.
What I think happened is that all of Europe made a commitment to upgrade their diesel standards to allow for these new engines, and that the trucking industry here won't go along with that because it increases the price of the fuel. At least this is my theory.
Does anyone know?
Because their system allows for much better performance and quantum leaps in fuel economy that we're not permitted here and I would like to know WHY? Originally Posted by theaustinescorts

This requires some expensive exhaust after treatment in the form of particulate filters with purge cycles that temporarily burn excess fuel to bake out the soot that clogs such filters. The devices exist now on all 2007 and later 3/4 ton and bigger pickups from the big three, and they have been very unreliable. The purge cycles put a big dent in fuel mileage, and the added displacement needed to overcome their power loss puts another big hit in the economy. Diesels which used to get 21 mpg in a 3/4 ton truck like a Dodge cummins 5.9 diesel now are lucky to get 13-14 mpgs with the bigger motor with the particulate filters. The financial payback on such trucks requires lots of mileage to make a difference over the gas versions. With smaller diesels, you still have to add these expensive filters plus some kind of treatment for NOx emissions like urea injection. More expense again. Top that off with the need for ultra low sulfur diesel, and the added expense to refine it, and diesel is now more expensive than gasoline. Where I think diesels will make better inroads here is as the power unit for hybrids where you can design a near constant speed unit that can get low emissions with minimal after treatment using tight control of the fueling system. Maybe Subaru, VW, and BMW will also change perceptions here some. For me, I love my old dodge diesel and newer Jeep liberty diesel, but I'm in the minority.
