Seafoam or BG-K44 Users
Has anyone used Seafoam or K44 on their high mileage E34? If so where you able to see any change in performance or mileage? I heard that Seafoam clears out the built up carbon. And K44 cleans out built up gunk. I'd like any first hand accounts prior to trying them myself. I plan on doing a compression check before and after.
