I have a 2018 Ram 2500 with the 6.4 L Hemi. I did tons of research on this truck before and after purchasing it pre owned with 2100 miles on it from a dealership. The pre owned certified warranty extended to 5 years. Had to have the Anti traction/ ABS module replaced twice and now it is an actual recall.
So the 4 crucial rules to keep the Hemi tick to a bare minimum and top end motor repairs as mileage gets up 80k and more are as followed: 1) - Make sure the oil you are using has the "MS#####
certification rating that is listed in the owner/service manual for your model of motor.(oil change/type area). Currently for mine there is only 3 manufactures that carry the rating for my MS number. Pennzoil, Shaffer's and Redline. I use Redline and after around 1500 miles ticking went completely away. 2)Change oil and filter at 5000 miles or less and once a year if under 5k. ( oil is always less expensive then the components)
3) keep idling to a minimum 4) Turn off or Delete the MDS( Multiple Displacement System) this is when 2 cylinders electronically drop out for "ECO Mode". Can Shift truck into 6th or 8th gear; when Tow Haul is activated or buy a module as I did and it piggy backs to the OEM ECU. I went with the Pulsar brand. Hope this helps.
