For best performance and maximum protection under all types of operating conditions, the manufacturer recom- mends engine oils that meet the requirements of FCA Material Standard MS-10902, and that are API CJ-4 certified and meet the requirements of FCA LLC.

CAUTION!
Your vehicle is equipped with an advanced technol- ogy Diesel Engine and an emission device designed to limit Diesel Particulate Emissions from being released into the atmosphere. The durability of your engine and life expectancy of this diesel particulate filter emission device is highly dependent on the use of the correct engine oil.
We recommend you use 5W-40 synthetic engine oil such as MOPAR or Shell Rotella that meets FCA Material Standard MS-10902 and the API CJ-4 or ACEA E9/E7 or ACEA A3/B4 engine oil category is required.
