3.0 Duramax concerns ?

My buddy has one and loves it. He claims 30mpg solo and 20 towing a 27 foot TT. The thing is super quiet. If I remember correctly the thing puts out more power than the first V8 Duramax. The only thing I don't like about it is the price.

The LB7 was like 325 hp and 520 torque, but still it specs pretty well. The price I think is cheaper than I thought it would be for the motor. When rumors of this motor were coming out, I really expected it to a 5K upgrade to buy in. Initially it was like to 2K above the 5.3 and then they reduced the price recently again. I have to believe that they are likely subsidizing this motor or pricing very close to cost in hopes of selling a lot of them to make it pay. I think GM and Ford, unlike Nissan when they released their diesel 1500 for a short time, found the sweet spot in power/capacity and economy. You need enough power to do half-ton type things, but you have to get high mpg to make it all worth it. I think both did a great job in doing that.

Personally have never heard any bad. They did start right with a simply torque machine design straight 6.

Yup...460 lb-ft @ 1,500 rpm = towing machine.

I know a couple of guys that have them. The only issue I have heard is they think that it uses more DEF than they would have thought they would. Everyone loves the nontowing MPG though.

I have a Ram 2500 with a 6.7 Cummins. It just sips DEF when being driven by itself but when towing I'll use a jug of DEF about every 650 miles. Hook a boxy RV or car trailer behind any modern diesel and the fuel and DEF consumption will definitely increase.

I don't have a 3.0 Duramax, but have a 3.0 EcoDiesel. I am a huge fan of the 3.0 diesels. If I were buying a 1500 truck today, it would absolutely have one of the 3.0's.

Our son has had a GMC for about a year now. Tows a 24 ft Lance TT. No problems at all.
