because it is the leftover oil that we use in cars...
Well...., the reason the price is so much higher has to do with the makup of diesel. Untill a few years ago the US allowed more sulfur in our diesel than anyone else in the world. When the US Government decided to lower the allowable sulfur content in diesel, instead of matching the rest of the world, they decided to make it lower than anyone else allows. What that did was remove us from purchasing diesel on the world market since no one makes diesel that meets our new standards. It also required the US refiners to spend a lot of money to retool for the lower standard. Since no one else but the US needs this lower sulfur diesel the market for it is limited to the US. Simple economics. The refiners must make a more expensive to produce product that is only used here. Ergo, high prices.
They don't. Diesels get better mileage and last longer.
the new diesels have great emissions, and get double the mpg, the old diesels have poor emissions though.
defnetly diesel
diesel.
Diesels almost always get better mileage than gas engines, some like the Volkswagen diesel are very efficient. The fuel is quite a bit more expensive though so do some math first before buying. Compare the mileage estimate of the diesel and the price per gallon of fuel against the same data for the gas. The best solution would be a gas electric hybrid.
Diesel.
Probably the best way to get better fuel mileage would be to get a tuner for it.
Better mileage
It obviously depends on the cars being compared but generally Diesel provides better gas mileage.
Yes, they get better mileage, more torque, and are cleaner burning. You can tow twice that with a diesel pickup than you could with a gas pickup. Diesel cars get amazing mileage. 55mpg for a volkswagen Jetta TDI.
Yes, diesel trucks generally get much better gas mileage than regular gas trucks. They even sometimes get better gas mileage than hybrid trucks.
You get much better gas mileage from diesel, but environmentalists don't like how dirty the exhaust from diesel is.
