If I'm in driving down the highway in Overdrive with the torque
converter locked, does that mean that my drive shaft is spinning faster
than my engine (hence Overdrive)? If that is the case, wouldn't going
faster (but still keeping the torque converter locked) increase my gas
mileage?

Why is it recommended not to use more than one treatment of fuel system
cleaner every 10k miles (or whatever it is). What negative effects
does it have if you use it too often?

depends on the motor efficiency and how its running, along with hills and
turns and stoplights and all that stuff ... my car for instance gets better
mileage at 85mph than it does at 65 or 55 ... but that's on the highway, in
town, staying out of overdrive and keepign the revs around 1500-2000 works
best ... of course that's harder to do in an auto than in the 5spd ....

You'll just have to experiment and see what works and what doesn't with your
truck ... anything from gear ratio to wether you drive up hill or downhill
more can affect it ...

I have fuel leaking from the rear tank into the front tank. I was told the
check valves will prevent this.

As I understood it, when you're in Overdrive, the driveshaft is
spinning faster than the engine. Wouldn't that get you the best gas
mileage?
Also, to keep things focused, let's assume I'm on a flat highway in
clear conditions.

Subject: RE: FTE Perf - OD and Gas Mileage

yes
and no

first, the driveshaft is spinning faster than the engine. but as far as
mileage....

if friction didn't exist, it would. as speed increases, so does the power
required to maintain that speed (not to mention accelerate). so there
comes a point, when your foot is in it too much to maintain the speed, and
mileage drops. air resistance, tire hysterysis, and all drivetrain parts,
add friction. so, at 65, you may be barely into it, but at 90, you are
applying far more energy to maintain forward motion on a per mile basis
than at 65. although it takes less time to cover the distance, more energy
was needed to travel it.

my experience shows that every vehicle has a different sweet spot that it
gets its best mileage at. for my vehicles it has ranged from 65-70 for my
other brand truck, to faster for my 460/c6/3.50/33 ford truck. (well, if
you can consider single digits "getting mileage") i have a bike that likes
close to 100. alot depends on gearing, and the engine itself.

just as a fyi:
i had a ford probe gt turbo. it had one of those trip computers on the
dash that gives instant and overall mileage, eta, etc. the tranny went out
on it one day. i drove it home in third gear, at high rpms, at normal road
speeds. i got over 30 mpg out of it then, where as when using fifth gear
OD it was always in the high 20's. (dropping alot if i ran it hard)

third gear is far from overdrive, but it got better mileage. yes, the
turbo was not on boost, but it goes to show how sometimes things are not
waht they appear to be at first.

I used to own a 92 F250 HD 4x4 460 E40D, and I seem to remember
something about the check valve issue which prevented the fuel return line
from sending fuel to the wrong tank Perhaps your local Ford dealer could
provide more info.
The last brake pull problem I had was due to a faulty caliper which had
a piston (lower piston) that was sticking. I replaced the caliper (under
lifetime waranty) and now the brakes work great.

Originally I thought you said in town, hence my issue comment of staying out
of overdrive ... but all things being flat and even, then yes, overdrive
would do you better as long as your motor had the power to actually pull the
truck and hold that speed ... when you get the gears lower and lower it
takes more power at a lower rev to hold the power you've got ...

Don't know. i always wanted one in my tow vehicle, but have never seen
one. I imagine, it might be possible to fab a ford unit to it, but that is
definately beyond my ability, or at least beyond what i want to try. i'd
rather put my effort into finding that last couple horses or traction to
win on the track.

I replaced both calipers, turned the rotors, replaced the pads and packed
the bearings with no change in handling.

Hi all:

My daily driver is a 92 F150 XLT 4x2 supercab with the 300/6 engine
and the mazda 5-speed.

I get about 15 mpg, and I'm reasonably pleased with performance.
However, I have a couple of questions:

1) The truck handles/corners like, well, like a truck. We do a lot of
mountain driving, etc, and experience a lot of body roll in the
transitions. Has anyone put F&R (anti)swaybars on their truck? Are
they worth it? Do they compromise i-beam travel, load capacity, or
anything else? JC Bolt-On has Hellwig bars for our trucks at a
reasonable price...

2) Are there any good perf mods (bolt-on or similar) for this rig? Can
I get a chip, for instance? A KN filter for my airbox, maybe? Any
other ideas? Would a hot manifold and/or a header help the factory
setup? Reccomendations?

Thanks much....

The caliper I replaced was still under warranty because I had just
purchased it a few months earlier. I was able to detect the piston which was
stuck by trying to push it into the caliper using a large putty knife. One
piston pushed in nicely, but the other was obviously stuck.
If the brake line was pinched, wouldn't that cause brake pull? Can you
bleed fluid from both calipers?
