Hey this is my first time submitting a question, but just wondered if any one knew if there is a big difference in gas mileage between an 79 F-250 and 350 4x4 standard cab my dad used to own a 76 ford that he made look more like a 79 and used it mainly to spray our fields with, when we moved he sold it. I also didnt know if anyone knew how much better gas mileage an older 7.3L diesel f-250 or 350 might have and the difference between the two. I also realize that in the gas the engine matters so how about a 390 comparison and also a 460, I hope Im making sense and thanks for your comments
Hey thanks for your comments, yeah I realize about Ford not making the diesel in the 79 model but just was wondering the difference between a 7.3 L diesel F-250 and 350, not between the gas and diesel, sorry about the confusion
By the time you are finished reading this you will be able to answer this question
This chart is for any engine/vehicle combination.
Considering the FACT there are so many variables regarding fuel economy it would be hard to get a specific answer.
Things to consider:
1)Quality of Fuel
3)Tune & Efficiency of Engine
6)Topography where you are driving
7)How much city/how much highway driving
8)Gear ratio & size of tires
9)Weight of the vehicle
11)Vehicle design (drag)
12)Clean air filter
Just to name a few.
I drive a 78 pickup with a well tuned 429 engine,at an altitude of 3400 ft above sea level,with normal weight on the truck with a canopy,tires inflated to spec,using premium fuel,2.75 rear,C6 Trans, With my foot on the pedal like there was a egg under it, in Canada in a city that the downtown is located in a valley.
