This is on page 293 of the owner's manual. Salesman was unaware of it's existence and I had a hard time finding the information. I have to question how important FCA feels the break in period is as I feel it would be in a more visible location. I'm aware of break in periods based on previous new ownership experience. Seems to be a controversial topic these days. I followed the break in as per the manual and all is good with mpg and oil consumption.
ENGINE BREAK-IN RECOMMENDATIONS A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle. Drive moderately during the first 300 miles (500 km). After the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable. While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. Wide-open throttle acceleration in low gear can be detrimental and should be avoided
Why this was buried in the manual baffles me too. I’m POSITIVE my salesman had no idea it was there either - when I asked him what type of oil the truck comes with from the factory his answer was “Ya know, regular oil...”
