Mileage - 93 GMC 6.5 Turbo Diesel
I have a 93 GMC 6.5 Turbo Diesel with a 5 speed manual transmission and I use the criuse control. This is an extended cab pick up approaching 70K miles.
This is my first diesel vehicle and I am learning the ropes and I really like driving this truck. I live in Montana and it makes going from point A to point B quite pleasant since these points can be very far apart.
On a recent trip to Minnesota in January, I average 24 mpg. I did have a tail wind that helped and I was traveling light. I normally average better than 20 mph.
I check my mileage at every fill up, so my mileage records have a good track history. I will see in better detail how things shape up when it warms up. So far winter weather has not slowed me down too much.
I enjoy this website and bulletin board. Keep up the good work; all the best.

Tire Size Can Make a difference too.
I had original rubber on my truck when I received it. The tires quickly played out as I started driving it over Montana gravel roads.
I replaced the old tires with Cooper 235/85 R16 10 ply. They are taller tires. Over 100 measured miles the odometer is reading about 95 miles traveled. I would imagine I am rolling faster than my speedometer indicates as well. But in Montana the Interstate speed limit is 75 mph. I ususally do not go that fast.
So, if I could have an accurate measure of miles traveled I might be getting even better mileage than I calculate.
My truck runs like a dream at 1800 rpm in 5th gear going about 65 mph, and I fit comfortably in it to boot. Happy driving.

Has that shrub burned out yet? Soon I hope.
I'm getting about the same mileage,
100000 miles on truck
1995 4x4, K2500
Stock with a FSD cooler
and straight through 3" exhaust.
I plan on putting a 40 horse chip in and am wondering what that'll do to my mileage. Also will be installing after market intake filter (cone style) I want to hear the turbo whine.
Right now I get 18/20 MPG at 1900 RPM which is about 61MPH.
Anything over 2000RPM and the gauge drops proportionally.
What I don't understand is how can a person with a lifted new 4x4, oh let's say a Ford F350 Crew cab just for kicks with a diesel can haul down the freeway at 80MPH and not be in the poor house. I see it all the time.
I've got a good job make good money, these guys must be running the credit up at the gas station.
