Which is better, the 5.3 or the 3.0 Duramax?


When it comes to fuel-efficiency, the 3.0L Duramax Diesel engine offers higher EPA-estimated mpg ratings. So, if you don't require the full 11,500 pounds of towing power from the 5.3L V8 engine, it may be worth it to go for the more efficient 3.0L Duramax Diesel engine for your trips to and from Ashburn.



How many miles can you put on a 3.0 EcoDiesel?


Some owners report driving between 200,000 to 300,000 miles on their EcoDiesel engine. That's significantly longer than many gas-powered engines built to last at least 100,000 miles and up to 200,000 with proper care. That means you'll get as much as 50% more time behind the wheel.
