If I was you I would be telling people to get over the whole MPG thing on the 08 too. Your getting 12.4. I was lucky to get 7!!! Thats quite a difference for the same truck. Diesels are know for getting better MPG. Research? Nobody said anything about the MPG on the 08 when it first came out. The only people who say anything about the MPG are the current owners. The truck has got outstanding reviews form all the magazines. I love my truck. It is the best truck I have ever owned. I just think the MPG could be alot better and shouldn't vary so much from owner to owner.
