Liqui Moly 5-6K is the most I would do.
Depending on the LM those must be ALL city miles. Elf, Liqui, Motul, and M1 in various forms are 10k plus oils in a highway based commute.
The above have diesel oils that crush 10k OCI as per car maker. With the above, I would argue that 13 to 18k mile OCIs are easy with my commute, which pushes 500 a week.
