good MPGs . . .
you see alot of question about improving MPGs. I am tickled to death with what my new '89 beater is doing. I'm getting 26 mpg on the highway with a full load of equipment ( 400-500 lbs ) in the bed and doing 65-75 MPH the entire time. Around my home, I'm getting 21-22. I had a '90 back in 1990 ( bought it new ) and it didn't do as well as this old truck is doing. So . .some of them are just sipping fuel :o)

same here. I ran 91 ocatne fuel in my 98 2.5L and drove it LIKE A BABY and when I say that, I mean it. went about 53 all the time all highway. I have a K&N, Dual-Exhaust and the Regular Cab stepside with a 5-Speed- 2 wheel drive. I drove 468 miles on 11.93 gallons of fuel. Believe it or not- it's true. I proud of the ole girl!

lol the vaccum guage idea was my auto mechanics teachers idea and i borrowed ours from the shop for a day and hooked it up to my intake vac line for my purge valve...and wow...i coulnt drive to keep it in the green if my life depended on it but he does and he gets 40+ mpg outta his lil geo with 230,000 miles

optimum rpm's for fuel economy
on a flat highway with little or no wind, in 5th gear, i can get 55mph turning about 2,200 rpms. on the other hand i can get 72 mph turning 3000rpms. just wondering what would be the better one for fuel economy?
i always thought it would be the 55mph but now i'm not so sure???

Then I drove back going 80 and it took 3 hours.
So which one used less gas? Because I cut off an hour and a half driving 80.

i guess what we have to do is make long mileage runs (around 200 miles should do it ), essentially on cruise control ... and see how many gallons the engine uses at 55mph vs. say 70mph..
it just seemed to me that i got a lot more speed out of 3000 rpms .. without a huge increase in rpms compared to 55mph...
i'm sure you can see where i'm going with this .. that faster is more efficient i just have to prove it somehow. this goes back to what the OP was saying at the very top of this thread.

Just keep in mind wind resistance goes up more at higher speeds so it requires proportionally more engine output, although that't not nearly as much fun to be in the right lane all day! You'll probably find that the slower speed is more efficient. I read that in designing the Bugatti Veyron it required exponentially more horsepower to overcome the wind resistance at 200+ MPH! They have to get several hundred more HP for a few more MPH increase at those speeds.

however.. we're not talking about 200mph only between 55 and say 70mph..
that fancy vw would only be in first gear!
maybe the tonneau cover would help...
