It gets about 9 -10 miles per gallon, hauling or
not.
Then you've got a problem of some sort.
I don't think anything is wrong with it, but it's got some very heavy
options on it. I've spoken to a mechanic about it. One is a very heavy
bumper, both front and back-- the type that allows you to hit a deer
and not tear up your truck. It came that way, but I just left it on.
It's also got oversized tires on it. I know that's not good, but they
are very expensive to replace, so I'm just letting them wear out
before getting some smaller ones. Because of the tires, it causes the
mileage to not be very accurate. What it reads as a mile is actually
somewhat longer-- about 1.2 miles or so, which I think is throwing off
the MPG.
I've got a K3500 with the larger gas engine. Bobtailing I'll get
11.5-14.0 mi/gal. The difference is how I drive. I've imposed a 60
mph limit upon myself (unless otherwise required). I REALLY try not
to "jackrabbit." If I stick wiith that then 14.0 is realistic; if I
do 70 I see 11.5 (if I'm lucky). Pulling (4h, SL, aluminum, finished
dressing room and mid tack) I'll get 7.5-8.5 depending upon speed,
terrain, load, etc. Again, I slow down and I do better.
Yes, the Ford manual states that going over 55 MPH will increase gas
mileage by up to 15%, IIRC. In this day and age, that is a lot.
If you've got a constant then I suspect you've also got an operator
that is careful with a load and a "lead foot" without one. :-)
I don't pull very fast. I really do go about 55 to 60 when I haul most
of the time, but sometimes it's very heavy (the load). I'm probably
not going to take much water with us in the bed this time, to
alleviate the extra weight.
Again, maybe so and maybe not in the "much less expensive" category.
Concur in the "easier to drive" when it comes to looking for parking
spots. ;-)
Yes, I've driven her truck before. It drives much more like a car than
a truck. Mine's much harder to maneuver, to park, to stop, etc.
As for Bill's note. I know you lose a lot of capacity going to a
higher altitude, but I don't know how you figure it out.
Google "horsepower vs. altitude" and you'll get multiple options for a
calculator.
Thanks, I'll try that.
My truck may
By 10,000 feet you've probably dropped to close to 50% of max hp. I'm
not sure about the torque curve (critical when discussing towing).
Maybe you could Google "torque vs. altitude"? :-)
Interesting-- I'll check it. I didn't know the % of loss, or how you'd
figure it, but it certainly was noticeable. When I did it before, I
was hauling two horses, a lot of feed and about 90 gallons of water
(at 8 pounds per gallon). I'm going to empty a lot of the water this
time, as it makes quite a difference.
Again, when hauling bigger is generally better. There are exceptions,
but none of the usual ones come to mind, here.
Yep, I knew it, but also knew the 150s were supposed to be more
durable these days than they once were, so didn't know if it could do
this or not. My friend talked to her dad about it and I've checked
with our engineer/mechanic friend, and everyone seems to think we need
to take my truck.
