What is the MPG of a 2500 Suburban 8.1L?

[greywolf2112]

Anyone own one of these?

 

What can I expect MPG on highway?

 

And about how much MPG when I tow say a 6000-7000 lb travel trailer?

Found this link in the 2500HD/3500 forum:

Looks like around 10-12 MPG not towing and maybe around 8 MPG towing your trailer.

Sorry bud, 'mpg' and 'big block' just don't belong in the same thread if you get my drift.

I get 10-12 mpg without a trailer, or with a small (Snowmobile/bass boat) trailer.

 

With a 30 ft, 10,000 lb travel trailer I get 6-7 mpg at 70 mph. This is a taller toy hauler with a bed above the garage.

 

With a 24ft, 7,000 lb car hauler I get 7-8 mpg at 70 mph.

 

I am running synthetic fluids and a K&N air filter. I have been told that I could expect around 1mpg with the K&N cold ari intake, but haven't tried it yet.
