2nd Gen Non-Engine/Transmission Club Cab Swap

Engine/Transmission (1994 - 1998) Need More Power

It's funny how the more things change the more they stay the same. I remember the 70's as a kid, sitting in the back of my Dad's 73 Buick Regal, waiting to get 5 gallons of gas, because of the OPEC embargo. The Regal was a factory 455 with dual quad carbs (yes, that was an option) and completely debadged, white on white... beautiful car.



In an effort to offset the fuel crisis, the government imposed the 55MPH speed limit; the thought was that if we rolled slower, we used less fuel. I suppose this worked, but I remember it taking forever to get from Shrewsbury to York, PA. Then, in the 90's the speed limit was raised, in most places, to between 70MPH and 80MPH on Interstates.



Now we find ourselves getting nearer to the 70's again, but in a different way. Oil production isn't being reduced, but it isn't being augmented either. Fuel corporations are, of course, in the business of making profit, so they have no qualms about passing along the increases they're seeing, as obscene as it may seem to us, the little guy.



As a result, I am rethinking my daily use of my beloved Dodge Ram. As it gets older, like me, new problems pop up. This time, it's fuel consumption. I have watched my mileage steadily drop, from 19MPG steady to 12MPG. My driving habits have not changed, so I suspect that the VP44 is starting to die, slowly but surely; I've already changed my LP to an AirDog FP100.



Since I'm a SSG in the US Army, and I don't make a fortune in this career, I don't have the luxury of buying another car, even used... . not yet anyway. I have been a die-hard "Buy American" kind of guy my whole life, but I see that American car companies' profits have been slipping over the years; Foreign car companies don't seem to see these losses.



My point to this rambling diatribe? Simply put, until I can afford to get a daily beater and temporarily retire my Ram to hibernation, I am throttling back to 55MPH. My mileage is staying at around 17MPG now, which I can live with for now. What I can't live with is living with $4. 18/gal for diesel. Even with the further refining processes needed for ULSD, I can't fathom why diesel costs more; Global supply/demand be damned, I don't buy it.



If we all try throttling back to 55MPH, we might use less fuel which, in turn, will hit the fuel companies a bit... . not much, maybe, but enough to hopefully make them notice and take action.

I don't consider this political, but practical sense to pass along to the rest of the TDR.

Throttling down

Yes I agree with you but they will just raise the price that we have to pay so that there profits don't go down. It is time for more gears in transmissions and and electronic shifted 2 speed rear diff. Give me money and I will reengineer things.
 
Good idea about driving slower. I have also been driving slower with the higher prices. Usually do about 60 to 65mph and have noticed a substantial increase in mileage.



Last summer, while driving in South Carolina, I checked my fuel mileage for 10 mile intervals. I used the overhead (which was pretty consistant at about 1 mpg high) for the following readings.



MPH MPG GEAR

70 * 12. 1 * 6

67 * 12. 7 * 6

65 * 13. 6 * 6

60 * 15. 1 * 6

55 * 16. 9 * 6

45 * 21. 2 * 5

40 * 23. 3 * 5



Oh, by the way, I was pulling a 29' travel trailer at the time, no wind, level roads.



Amazing what you will do when you are really bored in the wee early morning hours. :rolleyes:

It is easy to say, but not so easy to implement, I just made a run to California and back covering 4300 miles in 6 days, including 2 days of off roading, and dropping off a vehicle, picking up a vehicle, picking up a pair of fenders, and picking up a bed for my truck along the way. Going 55 instead of 75 for 10 hours a day, I'd still be in California (not that that would be a bad thing, weather out there was beautiful, and its pretty darned cold here), but I figure the extra I paid for fule was made up for with the 1 or 2 less nights at the Holiday Inn.
 
Murfman,



I have to respectfully disagree with you. Setting my cruise control has not been an issue for me, and I'm already seeing the results. I'm at 122 miles and in between 7/8 and Full.



If you slowed down from 75MPH to 55MPH and drove, let's say 10 hrs (any longer and I go bonkers), you'd only be losing 200 miles per day... . I can live with that and stay at a cheapo motel for $50/day vs paying $117 to fill up my tank at $4. 18/gal (28gal average fill-up) every 316 miles (11. 3MPG average, driving 75MPH).



I don't know, to each his own, but with 4. 10's I can't come up with another way to save fuel, given my situation. If you have the money to spend on fuel and drive 75MPH, then more power to you; I just can't.
 
The single, most effective thing we can all do is DRIVE LESS. If oil inventories go up the price will go down. Driving slower does help but doing that in places like Nevada is painful. "I can't drive 55".

I feel your pain, I can't either.

FWIW the price for a can of beer went up at my golf course. It went from $2. 75 to $3. 00 per 12 OZ can. That one bakes my noodle even more. :{:{:{
