NUMBER: 09-011-20 GROUP: 09 - Engine DATE: July 24, 2020 This bulletin is supplied as technical information only and is not an authorization for repair. No part of this publication may be reproduced, stored in a retrieval system, or transmitted, in any form or by any means, electronic, mechanical, photocopying, or otherwise, without written permission of FCA US LLC. SUBJECT: 6.7L New Oil Usage Information OVERVIEW: This bulletin provides information regarding the correct oil grade to use on the 6.7L Cummins used in the 2019 and newer HD Trucks. The following information is intended to eliminate confusion. MODELS: 2013 - 2020 (DJ) RAM 2500 Pickup 2013 - 2020 (D2) RAM 3500 Pickup 2013 - 2020 (DD) RAM 3500 Cab Chassis 2013 - 2020 (DP) RAM 4500/5500 Cab Chassis 2016 - 2018 (DF) RAM 3500 <10K LB. Cab Chassis NOTE: This bulletin applies to vehicles within the following markets/countries: North America. NOTE: This bulletin applies to vehicles equipped with a 6.7L I6 Cummins Turbo Diesel Engine (Sales Code ETK, ETL, ETN or ETM) DISCUSSION: For all trucks, regardless of model year, located in areas where the ambient temperatures routinely fall below 0°F (-18°C) during the winter, it is required to use 5W-40 synthetic engine oil that meets US Material Standard MS-10902, and API CJ-4. Oils that meet this requirement can be found through Mopar, as well as Shell in the Rotella and the Rimula families. Although this grade of oil is required in colder climate areas, it is also safe to use during the summer months, and in warmer climates as well. However, for vehicles normally located in areas that routinely stay above 0°F (-18°C), there are two grades of engine oil recommended depending on the model year of the vehicle: • 2018 model year, and older vehicles, it is recommended to use 15W-40 engine oil such as the Mopar, Shell Rotella and Shell Rimula branded oils that meets US Material Standard MS-10902 and the API CJ-4 engine oil. • 2019 model year, and newer vehicles, it is recommended to use 10W-30 engine oil such as Mopar, Shell Rotella and Shell Rimula that meets FCA Material Standard MS-10902, and the API CK-4 engine oil category is required. Products meeting Cummins CES 20081 may also be used. NOTE: Always refer to service information and/or owner’s manual for exact engine oil recommendations. CAUTION! 15W-40 grade oil CAN NOT be used in any 2019 model year or newer 6.7L equipped vehicles due to the new designed valve train of this engine. If this oil is used, it will cause deposits to form in the Hydraulic Valve Lash Adjusters leading to undesirable noise, and/or engine damage. For any additional information regarding oil usage on these vehicles, please be sure to refer to the owner’s manual. POLICY: Information Only
