I have a 2000 F-250 Super DutyV10 and I have alotof trouble pulling loads. I used to have a 2001 F-250 deisel V8 that would pullanything with no problems.Is there really that big of a diffrence between V8Deiseland V10 Gas. I mean this V10 barely pulls about 2000 pounds through the mountains here in Utah. I really struggle going up steep grades andfeels likeI have to keep thepedal flooredand turning between 3500 and 4000 rpm's to make it and maintain 45 to 50mph. Thats horrible. You knowI love Ford trucks but this truck has really let me down oramI just expecting to much out of a non deisel truck.This truck does have 165k miles on it butI still think it should do better than that.Also I've done the tune up and put bosch platinum plugs in it even put a K&N filter charger on it and I'm still struggling.
So my big question is were V10's built to pull heavy loads or doI just need to go back to a deisel?

 

In this day and age diesel engines in light duty trucks, medium duty trucks, and heavy trucks rule. Diesels are made to pull. they are designed to work and work harder than any gas engine in the market. What helps diesel pull is their very high low end torque. Torque is what pulls and is what moves a vehicle. horsepower is not as important when it comes to pulling. but nowadays a diesel can much easier make more horsepower than a gas engine. a gasser wont ever match the torque a diesel engine can generate. I advise you to go back to a diesel if you're looking to use it to pull expecially in areas with varying altitudes. at higher altitudes gas engines lose power because of different oxygen levels. in a turbo'd diesel the rate of power loss above sealevel is dramatically less because the turbo adjusts by forcing more air in in place of the lost oxygen. also im sure you've noticed the difference in fuel mileage between the gas and diesel engines. having a difference in two cylinders really does not sufficiently add up for the difference in engine types. you also mentioned the mileage on the v10. with ur previous truck it was only getting broken in. your 7.3L powerstroke has a rebuild life of over 400,000 miles. this rating is not made by ford but by International. Though many trucks taken care of properly have seen nearly 600,000 with out a rebuild. if you have any more questions feel free to contact me.

 

Their must be something wrong with yours. I have a 200o Ford Excursion
V 10 with 27 k miles on it, towing is all I use it for. I tow my 31' RV all over Oregon which has a lot of big hills.
I have the stock 4.30 gears and I even run 35" tall big mud tires which rob power. I use the truck weigh scales on most trips, I average 17,000 lbs GCVW Truck and trailer. I come out of Warm Springs hill ( a long steep pull 6% grade I believe) at 64 MPH with that weight. I can go over Mt hood at 60 with the same weight.
It is a gas motor and you obviously have to rev gas motors, deisels 1800 to 3000 RPM, But like any gas engine you obviously pull the steep grades in second gear revving, 4,200 to 4,400 works the best on the V 10. They like that RPM range and will pull long hills with heavy loads at that RPM without hurting a thing! Never gets hot, just spins out the RPM's and pulls!
No it wont run with the new 800ft lb torque deisels but I have outrun all the older deisels pulling hills.
