- I messed up, this was meant for the general forum...
(I might get down rated over this, but I wanted the widest spread interest to see this. It is in two other forums, and may be considered automotive, or suggestion...)
I wanted to find out how much support there might be for exploring our options in getting the most we can out of a gallon of fuel - whether diesel or plain old GAS.
I should have suggested this aeons ago, but the time is here, and the petroleum barons are jacking prices up left and right.
We've GOT to look at that - there are better ways to spend a gallon of fuel, and we should try like hell to FIND them...
Lightening trucks, streamlining, aerodynamics, wheel technology, fuel systems tech, transmission advances, tips to reduce friction, ALL of the above blends in to higher efficiency. And we need that now....
We should band together on a fuel efficiency forum, and find ways to make fuel stretch...
It would HAVE to be a tech forum, but I want to get the idea out there and attract attention to a very important topic in these times.

My big van is getting 9-11 MPG in the city right now, I'm forced to a big van. I need to put in lower gears, I have 3.50, combined with van wieght, they are too high for driving in the city and cause gear changes on the HYW. I'm wondering about an LPG conversion, that would be close to running Hydrogen in the far future too.
Handicap conversions for mini vans to make them wheelchair accessible is around $30,000 and the van can be no more than 3 years old, making them another $25,000. Full size vans require little to make do, and have no age limit, but burn lots of fuel.
I am getting ~25 in my Windstar. It's trans seems to shift about 5 times before it hits it's rock bottom RPM of 1900 at 60mph... At 80 it's turnin 2400 and the mileage stays the same.
Since right now they wont let us have light-duty turbodiesels, at least Ford and the rest could cut the weight instead of making each new design heavier than the last. The empty weights on the current generation of light-duty trucks is insane. There is no reason for 5000+ lb unladen "half ton" trucks. Even the latest Ranger is dripping with extra weight compared to my 2700lb 1988 model. A typically equipped SD is over 7000 before you put anything in it! A pre-1980 F-350 was more like 5000.
All of the expensive and complex computerized engine and transmission technology is not giving us better mpgs because of basic physics.
It seems that the V-8 engines from the 70's and 80's are making the same mileage as current day powerplants. My 77 F-150 has a 400 in it, which most people complain gets terrible mileage. I avg around 15-17 mpg. From what I have heard, most half ton trucks do the same today. So much for technology. You would think that after thirty years of OPEC screwing with us, we would do something about it...
I tend to think streamlining is at the lead end of the issue. Overdrive trannies help a lot, and wheel bearing tech is going to figure into it.
ALIGNMENT is a major issue. Any toe-in, or Toe out will eat up milage faster than a ball and chain dragged behind.
Dragging brakes are an issue.
Tranny design is an issue.
Whatever eats up horse power will fight against the power liberated by an engine/powerplant.
We need more efficient transmission. Some sort of hydraulic system that can operate at 1500 to 2000 rpms, and have sufficient pressure to run 65mph+. would be ideal. You wouldn't have to worry about idling. The "accelerator" pedal would be linked to a valve to allow fluid to flow at various rates to the motors. They already use a system like this in large trucks for industrial work sites. Current technology has us limited to what we can and can't do. We need smarter people, or at least real world people in those engineer jobs.
My biggest Beef. People who drive them big honkin Trucks/Suv's just because they can and really don't need them ( sorry guys ). The big three car company's are also to blame for pushiing the horespower wars to the N th degree, while forgetting all about fuel economy. I do realize that there is a place for big V-8's, V-10's, Hemi's, and big torque Monster Diesels. But eventually we will be paying similar prices for fuel like they do in Europe or Down under. I will forever have a full size truck in my life, but I think for my daily driving I am going for something alot smaller that sips alot less gas. I hope no one get's too mad at me, it was not my intention lol . I'm done.
Some time back I read an article on improving gas mileage. The two most beneficial mods were a small spoiler to reduce drag and an air dam to keep air from under the car. It seems that air under a vehicle's ragged undersurface tumbles and causes a lot of drag. Benz has specifically addressed undercar drag in some designs..... if your truck is high, so will be your gas mileage.
