Thank youI'm sure it wouldn't be much of a difference on the flat interstate but pulling mountains would make a difference I'm fairly sure.

In that situation the difference would be even less

What's the real world numbers on the 8.1 and 6.0?

TBItoy · Nov 30, 2014

6.0 will get about 14 mpg normal driving not towing. 9 or less towing.

8.1 will get about 11 normal. 9 or less towing. But has way more torque.

I don't have experience with the 8.1 in a burb with the 4L80 trans though, only in 3500 trucks with a 5 spd Allison.

Sounds like the FJ80/100 mileage without the pow wow

I had a 2005 Suburban with the 5.3. Finally traded it in with around 200,000 miles, leaking head gasket and rear main seal. Other than that no major issues with engine or tranny.

Pro's
Seats 8 for everyday use
Remove 3rd row, fold 2nd row down and sleep comfortably in the back on full air mattress when wheeling.
Rides like a Cadillac
Good turning radius
14 mpg around town(this should probably be in con's)

Con's
Speedometer clusters go bad around 100,000 miles (original and 2nd cluster from junk yard)
9-10 mpg hauling jeep

Clusters are getting cheaper though, Dorman is making them and will burn mileage and vin in for about $200 then it is just plug and play, they are also making custom clusters, white faced gauges ect for the same price.

Going to keep an eye on this thread. Really wanting to upgrade from my 97 1500 Suburban w/ 5.7 to an 03-06 2500 Suburban w/ 8.1.

Been looking for a great deal on one but no luck yet. Girlfriend checks Craigslist almost daily, we both love the Burbans. Most of them for sale are high miles with a high price tag.

If u can find one just get the 8.1, comes with a 4l85 beefier than the 4l80
it pulls a hell of a lot better than any 6.0 I've driven

Thanks for the info

I have had two of them .and I love them .....one of the best suvs you can get :****:
I've had the 6.0 and I have a 8.1 now I like the 8.1 better it gets better mpg then the 6.0 plus way more towing power I think because of the weight of the suburban the big block is much more suitable , plus a queen matress fits in the back so no more tent camping
mines for sell for the right $
