I didn't notice a change in economy when I went from 3.73 to 4.10 or when I swapped my 4L60 for a 4L80. Or when I put the blower on. It seems to get what it gets.
Okay so i have a 96 k2500 all stock except its on its third motor (second with me one before i bought) and got some different wheels the previous owner put on but still has stock tire size and no lift but i struggle to get anything better than 12mpg and i need some recommendations on how to get better mpg so any input will be greatly appreciated!!
So what’s your gear ratio? If it’s 4:10 with what 265/75/16? You’re probably about as good as it gets. Heavy 4x4 truck with low gears...it’s a trade off. You can pull stumps out but the mpg is gonna suffer.
what I would do is take out any stuff you may have stored in the truck that’s not needed.
I had a 1989 Chevy crew cab dually 4x4 454 with a Turbo 400. 8/9 mpg was all I got. I would of killed to get 12 mpg back then.
Fuel filter is a easy service. I doubt it’s gonna do much for mpg. Check your plugs, wires, cap, rotor and Air filter.
Keep your tires inflated to correct psi.do t hammer the throttle everywhere you go. When slowing down look ahead and let off the gas. Then ease back into the throttle.
Get rid of any protruding appendages like big lightnbars or roof racks etc.
another option is to find a front and rear axle with highway gears or regear but that’s gonna cost and its a long time to recoup the miney.
ultimately a Gearvendors overdrive will get that mpg up. But the 35/4000 cost kills any savings. I have a gearvendors in a f350 with a 7.3. 4:10 gears. The mpg goes from 14 with. O Gearvendors use to 16 with Gearvendors use. But it has to be long distance flat roads. Otherwise the only advantage is being able to split a gear towing.
Fuel pressure is crucial on the Vortec motors for the poppet injectors to fire correctly. They react worse than a TBI with low fuel pressure in some ways.
