Pardon me if it’s already been discussed. I have a 2020 Ram 2500 Hemi, and the owner’s manual calls for Mopar 0W-40 or equivalent (PUP). I just did my first oil change today at 3,900 miles. Sent a sample to Blackstone. What are people’s opinions on this oil? I want to continue to use it because I have a 150,000 mile bumper to bumper warranty with no time limit, and am keeping meticulous files on maintenance. I assume using what they recommend is probably best in case I ever have to avail myself of the warranty. I haven’t been able to figure out if the cam failures have been rectified on the 5th gen 6.4.
