gas mileage?

[goinbig]

By saying it doesn't have to work as hard, he means in the way the engine itself functions. It's a completely different type of engine, so it runs differently than a gasoline engine.

Please keep you posts to facts or stated opinions, and refrain from posting totally made up BS like compression ratios of 40:1, Really now.....

Fair enough. That was supposed to be a 24. No justification there, just to say it was a typo. Simple as that.

Are you aware that the average length of time a "new" vehicle is actually owned by the original purchaser is UNDER 36 months? That is from industry data and readily available from many printed sources. How far can you drive in 36 months? Well 25,000 miles/year is a lot, most leases allow for only 12,000-15,000 miles/year. So that would be 75,000 miles in three years at 25K/yr. Hardly enough justifiaction for a diesel. As you said, if you are towing heavy loads, then it's a no-brainer that a diesel is the best choice. This may also be the case if you tow often (like a lawn service) but the loads are not that heavy.

Are you aware that some people keep a vehicle longer than 36 months? I have put a little over 40K miles on my current truck in a little over a year. 14 months, to be more exact.

You also stated that a diesel does not have "to work as hard". How's that? It takes "x" Torque, and "n" Hp to pull any given load. That does not change wether you have a gasoline or diesel engine, the power and Tq required are exactly the same. Therefor one does not work harder or less hard than the other. Granted, the gasoline engine is operating at closer to is maximum ratings, but that's not what you said.

Christ, but you know what I meant... There you go with the nitpicking.

Since I work on the Powerstroke, 4R100, Cummins 6BTA5.9, 6CTA8.3, and GM 6.2/6.5L stuff EVERY DAY, as well as the 350, 301, 300-6, 4.6/5.4/6.8L engines, I have a far better idea of the maintence requirements of each engine than most people do. You see, our firm owns over 1,000 power units, 250 or more are diesels listed above and there are over 100 Ford gasoline powered vans and pick-ups too. The rest are big-bore Cat, Cummins, and Detroits. We keep out stuff 10-15 years, and put on 350,000-500,000 miles in that time in pick-up and delivery service. The vehicles that get lighter loads (vans and P/Us) mostly have gasoline enignes because the life cost of the diesels is too high. When the loads get bigger (vehicles get to "1 tons"), then we run diesels because a) we run them longer because they cost more up-front, b) they get better fuel economy, c) they wouldn't be worth anything with a gas engine when we are done with them.

Well good for you.

IIRC, this whole thing started with how you said that if FORD could pull more fuel economy out of their 5.4's:

If a 5.4L COULD get 20 MPG (at all), FORD would sell NO diesels, and Dodge and Chevy no "trucks" at all.

This is what I would like you to clarify for me. Where did you come up with that idea? Since you like to use a lot of industry data and readily abailable info sources, would you point me/us to a link that says something to that effect?
Or, as you said:

Please keep you posts to facts or stated opinions, and refrain from posting totally made up BS....

wow...

Such an intelligent response...

Are you too lazy to check for yourself, and I must do YOUR homework for you???

See for yourself what is considered "average" mileage for your area (it does vary by geographic areas you know).
