What fuel mileage to expect from a 700R4 equipped Blazer? - Steel Soldiers::Military Vehicles Supersite

I have a friend that is looking into buying a civi Blazer with the 6.2/700R4 combo. He asked me what mileage to expect from this truck, mostly freeway driving (<70mph). I told him that my TH400 equipped Suburban got 15mpg @ 70mph, so he could expect anywhere between 17-20. Is this too high?

Mangus580, I know that you have a 700R4 in your avatar truck, what do you get on the freeway? (I know that it wont be an "apples to apples" comparison, what with your truck having the turbo on it, but it will give me another data point."

I dont have a turbo on mine as of yet... But I am lucky to get the 15 you are getting. 3.08 gears and Overdrive dont mix well.

I also think I have a tired IP.

My brother had a civvy 82 6.2/700R4 combo with the 3.08s, and on a trip to Va Beach, he got almost 32... On the way home it was a whole different story though!

I thought I read somewhere that you had a 6.5 turbo setup on yours. My bad.

32MPG! What, is it downhill the whole way?

Pretty much downhill, yeah!

My M1009 runs 19 and 20 all local driving. Dont see much over 55. Planning on a road trip soon, expect 20 to 22 if I stay under 65.

20 mpg would make my friend happy. He wants a "full size" for his work truck. He is a private building maintenance contractor and has been using a 2wd BroncoII for about 2 years now. It was tiny, and got lousy milage for something so small.

If it's got stockish tires (29" 235/75R15) and 3.08 or higher highway gears than expect to see 20mpg easy around town. Guys report 25mpg easily with that setup on the highway. If it's got lower gears and/or bigger tires then expect a bit less.

20mpg even with the 31's and 3.73's would be totally doable.

Your friend can always experiment with alternative fuels. Half used motor oil and half regular gasoline works great in a diesel engine.

NOT IN A CUCV, please check what truck is being talked about before posting. The 6.2L is NOT a multifuel. Some wmo in with DIESEL is ok, but ZERO GASOLINE.

When the M1009's were brand new we got around 24 MPG in convoy ops it was nice to get them as we had been running M915 convoys with M151's and that was not fun. On really long trips once we got away from the base we would load them up on one of the M872's that had room and ride in the cab of the trucks. The CUCV was a great improvement to say the least. Ours gets about 22 MPG on the highway with our 33 inch tires. we do not go over 55 in it either.

I have often thought about the possibility of putting the OD transmission I have in my HD 4X4 Diesel Suburban in the CUCV it would be interesting because we are always riding high on RPM at highway speed.
