| What your mileage on stock engine?
I've searched the forum, but only found a comment here and there for an unaltered, stock engine with all emissions equipment. I was wondering if some people could share their city and highway mileages (and speed on highway) unloaded. I checked Consumer Reports, and their mileages for the Silverado 2500 Duramax were 9 and 21 (no speeds given).
Thanks.
