My starting mileage is the same as your goal.
But with relatively minor changes I brought my 1983 F-250 from 15mpg up to 25mpg average with mixed loads up to 3 tons (28+ running empty)
Vehicle efficiency upgrades: 28.5mpg (so far) in 2.5ton commercial truck
Its easier to have big increases when you are starting from such a low number. In a small car +10mpg may only be a 30% improvement, while for you that same 10mpg would be 90% better. 4mpg is totally possible. Ford wasn't trying to make these things fuel efficient in the least, so there is all sort of room for improvement. |
I am glad to read this, I knew of the diesel secret since I was a kid.(25 years or more) today, add turbo, and calm it down. wow. I always assumed, as america hurts itself for the capitalist, the diesel trucks into the high twenties raised prices...strangely so, as diesel is easy to get from petroleum.
My truck experience and the same 15 mpg left me scratching my head. I would swear that is a minimum. OE keeps the lean out for heavy hauling. If you are not hauling, get dynamical with the injection, if it means a piggy back computer. Step up ignition if it needs it, and even the oil pump.I have stepped up the carbs into 20s quite easily (3/4 ton 5.7 chevy)...but it pinged in loads. that is when I deciphered the "einstein" of trucks left as oem...they make it run pig rich to last the 5 year pay plan...
I still want a diesel, 1980s suburban style with something modern under the hood.
Is this a repost or am I caught up in a bigger repost?
