That describes mine exactly! When I get off my lazy butt and feel like
leaning way into the engine compartment I will do a leakdown test to
get an indication of valve condition...methinks the problem lies therein.
And a big thanks to Bill in Portland, DJ250r, Travis Moore,Mike Persell,
and Nick (Lingus0169) who shared their mileage woes with me.

Around where I live it's mostly 55mph zones. I get around 16-17mpg's with a
well taken care of 4.9 with 247k on it.---Nathan

I haven't done a leakdown test, but when I put a vacuum guage on it I get a
steady reading. Shouldn't the guage drop if I have a bad valve. I do have
blow by. I wonder if that has anything to do with it.

Subject: Re: 4.9l six mileage

I used to average 14-18 mpg when my truck was much newer. But even now, in
need of a carb o'haul and at ~194k miles. I'd be disappointed with 10 mpg. I
do have a 2.73 rear axle and 4 spd OD manual trans, which helps mileage on
the open (flat) road.

Sounds like there is quite a range of experience with this engine. As a
replacement, I wish Ford would sell a smog legal retrofit kit for installing
a late model 5.0 EFI engine. I know that some crate engines are available,
but even the smog legal ones leave a lot to the imagination.

Any one have any idea where the fuel tanks ground point is? (for the gauge
assembly)
I have a 1992 F-250 XLT with dual tanks. Both my tanks read around 3/4 tank
when full, The rear sender is new last summer. Occasionally the gauges go
blank (read zero) and after a few days they may start working again. Based
on all the symptoms, I think it's a common ground for the sender system, and
the ground is bad.
Any Ideas?
Steve

Joe: check the amount of vacuum. After I renewed the upper end (head
gasket and above), I have 23" at idle and the coasting vacuum pegs the
meter above 25". Seems like the old 6 is sensitive to valve/valve
guide/head gasket integrity. Rough idle and poor mpg might also be
vacuum leak at the carb base, EGR problem, or loose head bolts/warped
head. I'm betting on vacuum problems/mixture problems being responsible
for most of the poor mileage in this thread.

Thanks for the idea Bill. I have a vacuum guage I just took off my 64
Falcon so think I'll hook it up in the truck.

Subject: Re: 4.9L gas mileage

My sentiments exactly! I recently had a rebuilt 300 installed in my 89 4wd, 4 sp
manual with 3.08s (I think). The best mileage so far has been about 12.5 mpg with
an average around 11.5. I am running 31x10.5 tires which, if I am thinking about
this correctly, will cause the odometer reading to be slightly lower than the
actual distance traveled. So my true mileage may be a touch better than my
calculations indicate, but still, not any better than a 351W would probably give.

My '93 Flareside with E4OD has 110,000 miles. My back-and-forth-to-work
mileage, which is about 2/3 highway at 65 mph, is right on 18.0 mpg, and
when I tow my Mustang to the dragstrip and back, 155 miles - all
highway, the mileage is 14.0. I tow at 65 mph with the overdrive locked
out, so it's turning almost 2500 rpm on the highway. Understand,
please, that all of this is done in central Florida where the terrain is
FLAT.

My truck does a consistent 15.0 mpg. 1980 F100,
3spd,2.47rear,msd5,5w30syn,128K Miles,lwb,cap on the back. Appears to
be only pulling on 5 cyls. #4 is real low compression. Taps like it has
a bad hydraulic lifter but I've changed them. One of these days I have
to swap in a rebuilt. The truck has more power than I'm used to with my
Festiva and Aspire. I actually could use a smaller engine.

I know it would be WAY ugly, but has anyone ever spliced a Ranger front
end onto a full size lwb rear?

Well....I put in that vacuum gauge and took a run down the local blvd.
Idle is a steady 21", 45 mph is 16" so it's as if I am applying the go
pedal to it when I am just keeping a steady speed. Now I did adjust
the parking brake the other day so maybe I am having to overcome a
slight drag if I got that brake too tight. But that's for another day as
I lit the BBQ and am going to have some good old fashioned beef ribs
after I get my shower.
At least the vacuum gauge has a new home now.

Bill,
My vacuum is a steady 21. As far as the EGR goes, the truck had no plumbing
hooked up when I bought it. The EGR is on there but no vacuum line to it.
Everything is plugged up, just a vacuum line going to the distibutor.

The wiring harness and instrument are grounded on mine via a lug on the wiper
motor. It's also attached to the driver's side rear lower intake bolt.

Hi,

I have just purchased a 1981 Bronco (351C, C6 Auto) with a 4bbl Holley 600
cfm (i think).
I seem to get around 350km (220 miles) from a tank 120 litrs / 27 gallons.

As I was desperate to get better economy, I took it to the local mechanic
who gave it a tune and changed plugs, leads, fuel filter.
He also replaced the carby base plate gaskets as he said they were leaking.

It runs smoother now, although it seems to stutter when you take off from a
stop / crawl, but idles fine at 900rpm.

It still seems to be just as thirsty.

If anyone has any ideas what to look at next, could it still have a manifold
leak, or maybe over jetted ??

Thanks for your 2c's worth.


John

I operate an 1981 300I6 but a salesmen who tried to sell me a 1993 F150 351
efi 4wd claimed that this engine was good for 8km /litre (this is around 22
mpg).Is this accurate.

Is anyone on the list aware of a conversion from the I6 to the 7.3L Ford
Powerstroke navistar engine in a F150 , I know Ford offered these in the
F250's only.What fuel consumption do these engines give?.

James
