Post your gas mileage
« on: July 1, 2005, 03:29:25 PM »
Can you guys/gals post your truck specs and what you get for gas mileage?  I'm talking lift size, tire size, axle gearing, and motor specs.  Also the year and what the vehicle is.

I'm going to figure mine out soon for my 84 RC and I'm curious to see how mine compares to others.

    I was doing 20 mpg hwy with  4.10's,  np435,  light wheels and 33's,  360,  splitter, fully covered bed.    Went to 35's everything else still the same and went to 19 mpg.    The new motor seems to be doing better on gas so far but it hasn't been tested as fairly as the other motor,  but going by days of use vs gas in tank vs the old motor in city driving and she is better.

Mine is a '75 D 100 with a 400 2 bbl, 31" tires(BFG's), 4.10 gears and 727 w/ NP 203 full timer..
It gets 8-10 mpg in the summer with the plow off and 6-8 mpg with the plow on.
I may throw a 4 bbl on it soon for S&G's, but I doubt I can stand to run on the primaries alone to get the mpg up.....I have a heavy foot.
This beast is mainly used on short trips around town to the dump, to the store, to the fishin hole.

Did you do a conversion? maybe the injectors are to big for your application.

No, I think the computer is the problem.  All of the sensors are new, but I am having problems with it.
I did a how-to on the conversion.  It was working great for a little while, but now it is missing/popping/backfiring when it gets hot (I think that is the cause).  I don't feel like shelling out the $150 for a new computer right now, so I won't be driving it.

You're not going to have much of tires left at 50 psi...
  I've had these tires on the truck for 25 to 27,000 miles now and they are wearing even with tire rotations every 5,000 miles and they're still over 1/2 tread.  Maximum tire pressure rating on the sidewall is 50 psi.  Vehicle data tag in the door jam calls for 50psi front and 60psi rear.  This truck tows loads of scrap to the local metal shredder and usually weighs out 10-14,000 lbs lighter when it leaves hence 30-35psi in these tires isn't gonna cut it

Managed a pretty consistent 11 mpg around town out of the '88 RC with a stock 360, NP435, 3.21 gears, 36" Buckshot Radials under a 4" spring lift.  I just returned from 3 years in Japan and am in the process of installing a warmed over 360 w/ 9:1 CR, 587 heads, and 4.10 geared Dana 60s.  Hoping a little better mpg with the new engine and improved axle gear ratio.

Fast foward to 2007-  Getting 10 mpg around town, 12 on long highway runs with the D60s, 4.10s, and 37s.  Motor is a 9.25:1 CR 360 with Edelbrock heads, ported stock 4bbl intake, Q-jet, and MP 260/268 cam.  Currently using stock exhaust manifolds although I've got a set of Hooker headers to install.

That would be a max of 60# you need to adjust the air pressure to the load. if its empty try 35-40 if you want the abilty to carry the max weight rating of the tire inflate to 60#

yes, unless you are FULLY loaded all the time, you should only run about 75-80% of the max rating.

If the tire is rated for 5000 lbs at 50 psi, then you have 4 tires, so that's a 20,000 lb load they can carry.  Why wear them out if the truck only weighs 7000 or so ?

  I guess that's aiding why im doing 19 mpg.   For the truck to ride smooth it would need 5 psi in the tires,  at 40 psi the tires start rolling over and scrubbing for the cornering i do

I get about 9mpg highway. Drop that to 4 if my foot is feeling heavy.

...and that's why it's a toy.

With 33's, a 318, and 3.23 gears, and 727 trans I am running about 2300 RPM's at 55. Does this seem normal?

Seems to be about the right rpm.  There may be a link in the "links" section to an online rpm calculator.  But I think you are right on.


Cheers

Low mileage , always in tune , and i run premuim plus  octane booster .
You need only two tools: WD-40 and Duct Tape. If it doesn't move and it should, use WD-40. If it moves and shouldn't, use the duct tape."

I dont know how you guys get that kind of mileage, my 97 gets 12 on a good tank and my RC last time I checked got about 8-9.  I just started running acetone in my 97 so I'll post any changes in the acetone thread.
