SAE VISCOSITY

An SAE viscosity grade is used to specify the viscosity of engine oil. Use only engine oils with multiple viscosities. These are specified with a dual SAE
viscosity grade which indicates the cold-to-hot temperature viscosity range. Select an engine oil that is best suited to your particular temperature range. 
Refer to your engine oil filler cap for the recommended engine oil viscosity for your vehicle.

For vehicles equipped with a Diesel Particulate Filter (DPF), use a fully synthetic, low ash oil that meets Chrysler Material Standard MS-11106.

For vehicles not equipped with a DPF, use a fully synthetic oil that meets Chrysler Material Standard MS-10725.

ACEA Categories

For countries that use the ACEA European Oil Categories for Service Fill Oils, use engine oils that meet the requirements  of ACEA A1/B1, A2/B2, or
A3/B3.
