POWER PROBLEMS
I have a 1989 f-250 with a 7.3L diesel. No turbo.
I never get any black smoke no matter how hard I pull or throttle it.
I am only getting 10-12 mpg.
I was told this eg. should run around 3000rpm. I don't thank that is right.
How can improve this fuelmileage? I have already tried fuel additives.
And where is the horsepower (rpm) on this engines.

Mileage can depend a lot on what gears and transmission you have.

just like a gas engine,when the performance and economy are low,you start with a basic tune-up.downside to this is, a diesel tune-up cost more.but this is known and planned in when considering buying a diesel......hopefully.
