I added 7.5oz of B-12 to my sump today as a test. Ive been running 5w-30 lately due to oil consumption in my 318i, as I wanted to limit converter exposure. I added the B-12 not because the engine was dirty at all or because of the consumption, it was because there is a lifter tick at cold start. Not sure if it is related to the consumption or not, but since nothing else fixed it, I figured Id give this a try. I figured Id go for a short OCI and then replace with something else when the weather gets warmer.
