2013 Chevrolet Black Diamond Avalanche Crew Cab LT 4dr Crew Cab 4WD SB (5.3L 8cyl 6A)
I have a 2013 Chevy Back Diamond Avalanche this is the 3rd Avalanche I have owned, the first two I had did not have the Z71 package. The ride was exceptional, and the vehicle was so quiet that you could not hear very little outside noise or road noise, the gas milage on the first two vehicles for highway would average 18 to 22 miles on a trip, the only complaint that I have is the Z71 gas mileage highway tops out around 19, I run flex fuel alot as the time,where I live is around $1.29 to $1.59 per gallon, I have been told that the mileage will drop using flex fuel. But the reduced cost I feel makes up for the difference. The Z71 does not ride as good as the standard model, but still is much better than the trucks I have had, and also better than the cars. I hated to hear that they are know longer making the vehicle.
