I have one of the 1/2 ton Silverado with the 3.0 liter inline 6 cylinder diesel and I like it alot so far. About 8000 miles and the average over that time is 23.5 mpg. I have had trips on 2 lanes at 58-62 mph that have averaged 28 mpg over 200+ miles. Quiet and comfortable to drive.
Those 1/2 ton diesels are mighty slick. The mileage they’re getting is pretty darned nice.
