This just posted today. Don't even have a product page yet. Assuming it will show tonight or tomorrow. With post as soon as it shows.
Finally have a 15W-40 option in a CJ-4 oil for the 07 and newer engines. This product has a TBN value of 10.4, as does the new 5W-40. They've upgraded it from the 8.1 it was. Both of these are now recommended to run 3x the OEM interval.
More info to follow..... -
