3/4 ton gasser gas mileage?

Monday we are going to try out a 3/4 ton gas Silverado 3/4 ton, 4.1 axle ratio, 4WD. Going from a Tundra because we've run out of GVWR on the truck (because we take too much stuff).

We get 8-9 MPG in the Tundra towing 8K lbs. What kind of gas mileage is anyone getting in the 3/4 ton gas Chevy's or GMC's with similar gear ratio --- solo and towing ???

Thanks.

    Hmmm. News to me. I never heard the owners I know or any of the fiends and family that build them here in SA call them that. Carry on then.
  • I had a 2015 3/4 ton Chevy with the 6.0L gas engine and 4.10 rear end and towed a 9K travel Trailer. 8 mpg - 8.5 mpg was the best I could ever do here in the Northeast where there's lots of hills where I towed. Without towing, I would average 14 mpg (combo city and highway driving). What I loved about the engine is it was a workhorse and had been around forever. What I hated about the 6.0L was it was nothing to write home about when you needed to get on it. I also wasn't much of a fan of the turning radius of the truck. Very wide radius compared to the Ram truck I have now.

  • Back to the original topic...You will get between 7 and 10 depending on the terrain and wind.

    Might consider going to a 3500 series truck. Not much more money and you will gain even more payload for all the, "too much stuff," that you say you take...

    Best to forget about mileage when towing..
  • X2

    The amount of work is about the same, so the amount of fuel expended is about the same...factored by a few things

    Like the BTU content of each gallon...diesel has more than gasoline

    The cd (coefficient of drag) makes the next component that factors

    Gear ratio down to pavement vs ICE architecture

    Finally, the biggest factor of all...your right foot vs terrain...

    9 towing an 8000 lb trailer is a little optimistic. I'd expect 7-8. Not towing will depend on your driving. Maybe 16 if you do a lot of highway, 12 if more around town. Check out Fuelly.

    Watch out for the outlier reports. People tend to take their best tank under ideal circumstances and declare that as their average MPG.

    Pretty common terminology for them,, even by owners.

  • About the same as your Turd. 4.10RE ratio is going to be your killer.
