I would believe it on a KW because it's more profitable to make a 400-500 mile delivery every single day with them. That van doesn't have much payload being an e250, so it's not going to allow him to haul much cargo. Factor in his salary plus how much they are paying him for mileage, hotels and food and that isn't a very profitable delivery. If he has that much stuff to deliver, that far away, every single day then you would think his company would use a tractor trailer, make fewer deliveries, save on expenses, etc.

Idling is a little worse than normal driving, but unless it's excessive idling(like on our job sites) it shouldn't cause any harm. What does make a difference is that it's miles don't show up on the odometer. That's why most industrial engines that do a lot of idling(tractors, etc) go by hours instead of miles. For every two minutes you idle it's the equivalent of driving one mile. So if you idle for 8 hours that is the equivalent of 240 miles. Those 5.4's and v10's that were dying with 125k miles on them probably had the equivalent of about 250-300k. Edit-Just did a little research and from what I found, idling is worse on a gasser than a diesel. At idle the fuel in a gasser isn't fully combusted, leaving build up on the spark plugs and cylinder walls, which leads to premature cylinder wear, oil consumption and loss of compression. Diesels don't rely on a spark to combust the fuel, so that isn't a problem for them.
Ok, I will have to try and keep my idle time down.
At least know I know why the 4.6s out of cop cars show so much wear.
Will a high Idle not fix the problem?

Another thing those guys with the delivery vans don't travel too far from their home base most of the time. They pick up a package and deliver it, then they're back to pick up another one and go with it. Sometimes they use a car. It just depends on what the job calls for.

When I was in the Air Force, I once broke an airplane at an airshow in Tampa on a Saturday afternoon. The part (worth 10 grand) was shipped from New Mexico and and on Sunday morning a FedEx Custom Freight truck showed up in Tampa. Who knows how much Uncle Sam paid to ship that part but I would guess that it approached the cost of the part of itself. Whatever it was, it was a bargain at twice the price.
Like Monster-4 said, sometimes efficiency or price is not a factor.

The only thing I can think of that could make it worse for a gasoline engine, is that gasoline is more of a solvent then Diesel.
As far as that million mile van goes - Ford invited him to take a tour of the plant where his engine was built. So I assume its legitimate.

Because it's not cost effective to use a truck to deliver one package (that is usually less than 150-200lbs) door-to-door the same day. I think you're missing the point of what Tom was try to describe what the owner of the 1M van did. These are critical custom deliveries where cost is not a factor (or at least not high on the list).

You are correct, but with the diesel you can just put it on the high idle setting and wet stacking isn't a problem. As long as you are idling around 900-1000 rpm your engine will stay hot enough to prevent it.

- Just a few PSd facts I found online thanks to www.internationalpowerstroke.com
- The 7.3 Liter Power Stroke is similar to the International T444E. The T444E is essentially the same engine as the 7.3 Power Stroke, but the "Power Stroke" name is only designated when the engine is used in Ford trucks. Power output and maximum RPM are the only significant differences between the engines. T444E stands for: Turbocharged 444 cubic inch Electronic (as in electronically controlled).
- The T444E has been made available in applications above 60,000 lb. GVWR, and extremely popular in the medium duty truck market while it was available.
- The 7.3 Liter Power Stroke was ranked in Diesel Power Magazine's top 10 diesel engines ever produced. Over 2 million 7.3 liter Power Strokes are still in operation today.
- Over 2 million 7.3 liter Power Stroke equipped Ford trucks are in operation. That's more than Chevrolet, GMC, and Dodge diesel equipped trucks combined.
- So Bill....Your sig sais your V10 can out pull a "stock" PSD. So I guess It would only be fair to tune up a PSD to International factory torque. Seeing that they were de-tuned for the F-series chassis to prevent trans and rearend warrenty claims.
- I dont recall them de-tuning the V10? After all "stock' is stock right?

Correct. The International version has always had less power than the Ford version. International builds the PSD for Ford, but Ford uses different injectors, turbos, and programming to give them more HP. The t444e had 425 tq, which is the same as the OBS PSD, but it made peak tq at 1600 rpm instead of 2000 rpm. HP was somewhere around 205 instead of 225.

"The PCM's (Powertrain control module) are different, thus the different power ratings offered between the 2 engines. For example, the T444E was offered in ratings up to 620 lb-ft torque, where as the Power Stroke was only offered with peak torque reaching 525 lb-ft. However, you may also notice that the 275 HP rating of the Power Stroke is much higher than any HP rating of the T444E."
I may have said it wrong. I was looking at torque, not hp.

Either way, it does not matter. When it comes to all out brute force towing speed/performance, HP is everything.
That extra torque that the International T444E makes will make pulling hills and the over all towing experience more pleasurable, but a V10 will still blow by every time.
