I have an IDI non turbo 7.3 1990, F350 4wd , auto, with a very heavy (1,700lbs?) utility bed. At 65 mph I get 14.5 mpg.
between 17 to 19 mpg
MY EXPERIENCE WAS 12-13 MPG WITH NO MOD'S
14-19 mpg just depends on what kind of drive train
Mine is getting 10ish without the overdrive engaging, so I'd guess it would do better with overdrive.
It seems to be around 13/18 city/Hwy
I know of a 1994 7.3L IDI (indirect injection) Diesel same setup as the 1993 and I am told that with an automatic transmisssion and dull rear wheels it gets 12 mpg. In 1995 the powerstroke engine came in, which may increase milage slightly for years 1995 - 2003.
all in all with the variations of rear ends average of about 15
depending on tire size and gear ratio in axle 15-19 mpg
I have a 1993 Lebaron with 3.0 Liter and Automatic. I get between 23-26 mpg.
The 1.4 liter engine does an average of 4.5 l/ 100 km or about 60 mpg
According to the EPA Fuel Economy Guide, all 1993 Cadillac models with a 4.9 liter engine rate as follows: Highway: 23 MPG City: 15 MPG Combined: 17 MPG
I have a 1994 Ford E350 with a 7.3 liter diesel motor. When I'm driving empty, I can get 14 mpg. When I'm pulling a 5,000 pound trailer, I get 10 mpg.
