"What do you mena with winter fuel?
As to my knowledge there is no product like that, diesel fuel have winter brands, but not gasoline."
Sorry to confuse you Ricracing, but here in the US we have winter fuels to reduce air pollution.
Here is a quote from the US Environmental Protection Agency ("EPA"):
(though I'm sure it was) you can go to the EPA's website: http://www.epa.gov/oms/oxygenate.htm#guidance
Having read the stuff on reformulated (for winter) gasolene - I'm not too sure why it would improve millage. Perhaps my car is just getting broken in at 12,000 miles.

State Winter Oxygenated Fuel Program Requirements for Attainment or Maintenance of CO NAAQS
Oxygenates are fuel additives (alcohols and ethers) that contain oxygen which can boost gasoline's octane quality, enhance combustion, and reduce exhaust emissions. The term oxygenated gasoline most commonly refers to the wintertime program that reduces emissions of carbon monoxide (CO) from motor vehicles. Although required by the federal Clean Air Act, winter oxygenated gasoline programs are implemented by the states. This section provides information about oxygenated gasoline, winter oxygenated gasoline areas, oxygenates (such as ethanol and MTBE), and health effects testing of oxygenates.

My Ride: E61 535d Apr 05. UK spec + Media Pack, Luxury Pack & Visibility Pack
From a quick reckoning, it sounds like most people get ~20 US mpg with a V8 and ~24 with an I6, which is about 20%. Whether that's not "much better" is fairly subjective.
However, in my experience, it's difficult to get in the high 20s with a V8, no matter how careful you are. With an I6, mid 30-s are attainable if you can drive with moderate accelerations/speeds outside cities. Not that any here have bought their cars with that in mind...

Its ironic that USA cars have winter fuels to reduce air pollution, when most cars in the states are huge engined - just look at the proliferation of 550i on this board....... and you are not signed up to Kyoto protocol....slightly pointless?
In the UK the average runabout is 1.4 litres and a 'big' car is 2 litres. And still they want to shaft us with punitive fuel taxes and charge us to drive by the mile via a satellite tracking system :'(
cheers

ps - im not particularly 'green' or anti large engined cars..... just wanted to illustrate the pointlessness......

If we in the US want to get serious about reducing our energy use and reduce carbon emissions - I believe the only way to do so is to raise the gasoline taxes - just as you in the EU have done. (It would have to be done over a 5-to-10 year period so that we would buy more economical cars before the boom was fully lowered. Still the folks in Texas who drive 200-to-400 miles for a high school football game on Thursday nights will still have a problem.)
We have tried to improve efficiency by EPA Mileage Rules ? akin to the economic rulemaking of the Soviet GrosPlan. It didn't work for them - and it hasn't worked as planned here.
First - "Trucks" were exempt - so we got the minivan and SUV. Then the automakers gamed the rules - why for example does/did the Corvette have a super-long ratio overdrive - to game the EPA mileage rules IMHO.
However, when gas got over $3.00 a gallon last summer ? the auto makers couldn't give SUVs away. Market forces had changed the American automobile buying habits. (Of course out auto companies who played all the EPA games reported record losses!)
I think that if one can afford a 550 - one need not worry about $3.50 or even $6.00 gas. It's the guy at the other end of the income spectrum and who drives a pickup truck that we need to worry (politically) about. Nevertheless, I say we should let the market work.
