Probably if Ford or Mazda had turbo'd them from the factory they would have caught on a lot better.
and Cooter... they make Kubota Quads that are diesels.







These guys drive to compete for the best milage, not hot rod it.... If I had a dollar for every diesel pickup owner claiming higher than actual milage I could retire....charliemccraney wrote:Well, I can't prove it since I was not with him during the trip from Miami to Atlanta, but he has no reason to lie.

Even so, 48 mpg out of an engine that produces 140hp and 236ftlbs is phenomenal. Are there any gasoline engines that are comparable?
I agree that if you look at the actual cost of a diesel vs gasoline it may not be as economical, but again, it's not yet mainstream so to expect it to be priced competitively to a gasoline counterpart is unrealistic. The volume is not yet there. That seems to be the case with most of these new "green" cars.

It's not just dirtier, the filters have to make it a lot cleaner for the HPCFR system, some of them run up to 30,000 PSI. IIRC VW pulled their tdi tourag off the us market because our fuel was too dirty and caused a lot of injector issues.Johnny Canuck wrote:VW redesigned thier diesels for cars in 2009 I believe it was. On my way to work I pass by a new Jetta sitting on the dealers lot with a 61 MPG sign on it. I assume they get that from the window sticker. That would be Imperial gallons. If it's true it's pretty good, my smart car has averaged 54 MPG over 3 years
I am not sure why you'd have to change out a fuel filter for diesel every 10000 mi, is US diesel that much dirtier than gas? The Smart with a Mercedes 3 cyl diesel is at 50,000 kliks without changing out the fuel filter.. no problems so far.

Ask anyone that has run diesels for a few years ULSD is different, not only does it get less MPG, injectors and pumps wear out quicker due to less lubicity. Even the change to winter blend fuel drops milage....Johnny Canuck wrote:One thing I really noticed was that US premium diesel really makes a power difference for me. Shell is the only Canadian one, doesn't seem to make quite as much difference.
I think this ultra low suplhur diesel is just a load of bull, especially out west here. Just another reason to charge more for nuthin, like when they charged more NOT to put lead in your gas.
Diesel grocery getters, family sedans are not mainstream. That is what I mean. Since average Joes believe that diesels are generally dirty, the auto manufacturers will not just jump right in and develop them for people who don't want them.fire truck wrote:How is diesel fuel not mainstream? It costs less to make it than gasoline, well before the ULS requirements it was, regardless diesel used to be a lot cheaper than gasoline. Diesel is far from new....
Yes I believe a 4 cylinder DI turbo gas engine could achieve similar power and MPG in a similar sized car. Think about it, the EB gets 22 in a cc f150 when the best milage diesels get 16.....
