I'm using LC in combination with Delo 400 15w40 in a '95 F250 Powerstroke Diesel. I have 1,000 more miles before I do a 3,000 mile UOA, the results of which I will compare with a 3,000 mile UOA of Delo without the LC.
I'll share the info. on BITOG when I receive the results.
I'm trying to outlast the current coldspell which is hovering around +15F. That's borderline for a 15w40. I'm hoping the weather will warm up a bit so I can get in the last 1,000 miles on the OCI.
