isnt that one and the same, if you increase the range of a tank of gass it costs you less to get to your destination.

Not at all. The cost of fuel is almost trivial when you include the total cost of ownership of a truck and RV

If you can go twice as far on a gallon, but each gallon costs twice as much, fuel costs per mile is the same. The extra money you spend for the engine to use the more expensive fuel is a loss.
But for most people that buy a new pickup every few years to claim to worry about cost to get there is silly, IMHO.

you lost me. why did the fuel jump to twice the price all of a sudden. and why are we talking bout different engines... this is all about the efficiency of these pistons, which realy is a cheep process to do, might add 500 bucks to the cost of building an engine if that..

this whole thread was about highlighting new technology which looks pretty cool and is showing some remarkable results through real world testing. and the post you replied to was just stating if a 25% reduction of fuel usage for the same distance reduces the costs of driving that same distance..

as for the buying new pickups every year, I don't personaly but I am almost done paying my truck off and I can tell you my diesel per month if I only ude the truck is higher than the loan payment, and that was when diesel and gas were the same price, laitly diesel has been 0.15 higher, normaly its 0.10 lower than gas but it seams to cycle up here.. so getting a 25% reduction in fuel uasge would be a huge chunk of change for people who actualy use there truck for more than hauling there camper once or twice a year.

What Scooby said has nothing to do with pistons. Not even remotely.

As StirCrazy said "There is more than the cost to measure value. Being able to increase range by 25% is worth something."

Not having to stop as often or worrying about giving out of fuel is nice. In virtually every discussion here about electric vehicles range is a key item. While it is less of an issue with diesels it is still an item.

If you are satisfied with your current range then you could carry 20% less fuel and increase your payload by 70lbs in a Superduty with the 48 gallon tank, or a 120lbs in my class A. Less time at the pump when you stop would be nice as well. Or don't use the extra weight capacity and have better performance.

A similar savings in DEF was reported. That is also worth time, weight and money. It is really amazing to me how some people blow off savings. It is almost like they are proud of how much they spend.

Let's look at the statement you questioned;

I am not concerned with how far I can go on a gallon of fuel. My concern is how much it cost to get me there.

If, just using numbers I can work in my head, a pickup with spark motor can take the load 10 miles on a gallon of gas, and the gas costs $3.00 and the diesel pickup can take the load 15 miles on a gallon of fuel, but the fuel costs $4.50 a gallon. Just counting fuel cost, how much do you save driving 300 miles?
For many RVers, and PastorCharlie might be one, don't drive enough miles in the life of pickup to save fuel cost compared to price increase when buying the diesel powered truck.

Now, about the piston design. There is no doubt in my mind saving 25% on fuel, without major power or durability loss, would be a game changer. And in fact, starting about '08 when a small fleet operator I sometimes hauled for bought half dozen trucks with emission controlled diesels I have said the manufactures need to jump to cleaning the combustion, skip trying to clean the exhaust.

You mean like the Lady at Cummins that spoke of them working on such a system?
