I purchased a new 2020 vehicle with the 5.7 Hemi. I drive around 2500 miles per month so 10k miles in 4 months or so. I read the owners manual and it appears you're allowed to go 10k OCI on these providing its within a years time. Anyone who has a newer Hemi do 7500 - 10000 mile OCI and have any UOA data? I saw a few Hemi UOA's from search but they all seemed older (I'm guessing after 2011 would apply the same though?). My plan is PUP 5w-20 (meets the Chrysler spec) and a Fram Ultra filter. I'm thinking 7500 mile OCIs but I'm not opposed to 10k if the data is there. I don't mind doing my own UOA's either once the engine has had at least a few oil changes. Sure is nice buying a new vehicle with port injection, cast iron block, good ol' American V8!
