- Hemi 5.7
I just bought a 2019 Ram classics with the 5.7 Hemi. This is the nicest truck I’ve ever owned with all the bells and whistles, rides beautiful and has good power. I’ve been reading all the threads on oil viscosity selection and I’m leaning toward full synthetic 5w30 (Royal Purple). My truck didn’t come with an owners manual so I went online. The 2021 owners manual make absolutely no reference to a specific viscosity. In fact, I guess I can use 10w30 as long as it meets MS 6395 specs.
My son lost his cam and lifters at 106,000 miles and always used 5w20 conventional oil.
So, I am more confused. Anyway, below it directly out of the 2021 owners manual:
“ENGINE OIL — GAS ENGINE
Engine Oil Selection — Gasoline Engine
For best performance and maximum protection under all types of operating conditions, FCA only recommends engine oils that are API Certified and meet the requirements of FCA Material Standard MS-6395.
NOTE:
Hemi engines (5.7L) at times can tick right after startup and then quiet down after approxi- mately 30 seconds. This is normal and will not harm the engine. This characteristic can be caused by short drive cycles. For example, if the vehicle is started then shut off after driving a short distance. Upon restarting, you may experi- ence a ticking sound. Other causes could be if the vehicle is unused for an extended period of time, incorrect oil, extended oil changes or extended idling. If the engine continues to tick or if the Malfunction Indicator Light (MIL) comes on, see the nearest authorized dealer.
American Petroleum Institute (API) Engine Oil Identification Symbol
This symbol means that the oil has been certified by the American Petroleum Institute (API). The manufacturer only recommends API Certified engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30, 5W-30 and 10W-30 engine oils.”
