8100 Mileage
I had a 03 Suburban 2500 with the 8100 Vortec.
Hauling nothing around town I'd get 10-12 MPG stop and go.
Hauling my 24 Ft. enclosed car hauler with my 61 Poncho ragtop I'd get 7-9 MPG driving 70-80. Trailer w/car weighs 7500-8000 pounds
On hiway with no trailer I'd get 14-16 MPG.
The 8100 has lots of guts for hauling.
I just got a 07 Suburban 3/4 ton with 6 liter engine.
I've got 800 miles on it .
Driving empty ( we live in rural Montana) I'm getting 16-17 MPG.
I hauled my trailer and car to West Yellowstone for "Rod-EO" and averaged 8.3 MPG driving 65-70 and it's a long cllimb to W. Yellowstone.
So far I'm satisfied and mileage should improve with more break-in.
Hope this helps.
