Q: aarcuda69062 wrote wrote no it wouldnt be a lean misfire. lean misfire comes from too much air and not enough fuel. opening the egr does not add more air. it does add gas which displaces air. displaces air -and- fuel. one can only guess what it is you are talking about. lets assume you were talking about a modern car with fuel injection. air gets displaced meaning less will enter intake at least for an instant. the fuel at the same time doesnt get displaced. there is nothing physical to cause the fuel to be displaced. id think the engines computer would sense the decrease in fresh air intake and reduce fuel delivery accordingly. -- tegger . 222 343573 sk9gj.24315$dt.7011@big1.bellsouth.net nunya i think you got your math wrong. there is absolutely no way in hell that i will ever own another gasoline driven vehicle. fuel economy is one of the lowest elements of the total cost of ownership tco. i do agree that using a 3.5 ton truck to get groceries is improper use of the vehicle. thats not my point. the fact that us auto makers are not offereing 2 & 3 liter diesels is the problem. the europeans have it correct. on another point sulpher in the fuel does not help an engine and it is not a lubricant. sulpher in all oil is the main contributer to the formulation of sulpheric acid which accumulates in the lube oil because of water condensation that occurs every time the engine crosses the dew point. this is what corrodes the oil. there are far more diesels in use in europe and the fuel there has been sulpher free for a very long time with absolutely no ill effects. the small diesel vehicle in europe consistantly see mileage like 60 mpg regularly. remember engine wear goes up with engine speed. diesels have no air control and make their power at lower engine speeds saving significant wear over the gasoline driven couterparts. the run onto diesels in europe has been so profound that the governments in europe have lost serious revenue as fuel is severly taxed to the point that the road tax and duties on diesels and diesel fuel have been drastically increased to compensate. please also note that diesel has 25% more latent energy by volume over gasoline and if the fuel is only $.50 more per gallon you are still getting a super deal. after all you pay by volume not weight. steve snip the op i was responding to was specifically about the fuel economy of dodge trucks. there were no references to european diesel cars. i usually spend a month in europe every year. it always astounds me how efficient our rental cars are. i usually rent opal turbo diesels. the last car i rented over there averaged about 55 mpg on diesel. it was as fast as a scalded cat and much more ergonomic than any american car i have ever driven. if it was available here in the u.s. i would probably purchase one. i will agree that diesel has much more potential than gasoline. but in american made full size trucks the numbers i quoted are correct. you cannot compare a european diesels stats to a 3/4 ton 4x4 truck with a cummins. since this is a dodge truck forum i have to work under the theory that we are discussing dodge trucks. and for overall cost of ownership the gas burner is cheaper for the first quarter million miles. after that the diesel becomes more cost effient due to the durability of the truck. heavier duty components combined with a slight increase in mileage eventually win out but it is it is a long time before that point is reached. michael .
