After some reading of posts and UOAs, it appears that opinions of LC20 are pretty mixed. In particular, I noticed that some recommend to stop using LC20 since it affects TBN. Is it true that LC20 can "ruin" perfectly good oil? What else are the potential negative effects of using LC? Increased wear?
I have less than 30k mi on 3.0L I6 Toyota engine running M1 5W30 and add LC at recommended dose. Mostly interested in minor cleaning/maintenance since I figure it shouldn't be TOO bad with pretty low miles. I was actually pretty ignorant and used to change oil (M1) ~once per year at about 7000mi OCI. I now drive more and intend to change at 6 months, 7500 mi. Can using LC be a BAD idea for my application? Should I be using a different oil (e.g. dino)? I am not really interested in spending money on UOA and don't want to have to throw out a perfectly good gal of LC. I would consider more frequent OCI using dino if more cost effective while still protecting/cleaning. I also use Pureone filters (1 per OCI). Am I doing something wrong? Thanks for any feedback.
