My brother's DIC showed a best economy of 28 mpg (8.5L/100 km) because there's a long downhill section of highway heading out of the town where he lives. Even he admitted it was lying.

I've gotten 9.0l/100 km -- 9.9l/100 km  ... highway, cruising 120km (75 mph) with occasional 130 (80 mph) to pass.  Distance of 500 kms.  I'm certain that it could be better if maintained 100 KPH.. (60 mph).

The DIC in my truck shows 13L/100 km when I do highway trips but I mostly do city driving so I haven't been able to confirm that with hand calcs.

I have been looking at dealer inventory around here and it is hard to find a truck with the 6.2 that isn’t completely loaded.Is this just a dealer thing or a gm thing?Think I might have to order one.
