Thanks for that link to the GM Diesel Page. That engine is a big step forward for GM to pick up that technology from Isuzu and Bosch. Wonder how the dealers service will handle this engine. GM service leaves alot to be desired with their pickup IMHO with my first hand knowledge of our dealer in our area.
The old Isuzu diesel pickup PUP trucks are in high demand by those in the know since they often get 500,000 miles off of one if the chassis and body can stay together that long, all the while managing to squeak out 50 mpg too. One of my close friends has two of them on his farm and they have been a piece of cake to keep operational. BTW, he really really like my two TDI's too!
