@zuckuss00; I would have to agree at least in my case. Before I spun a bearing in the block of my M52TUB25 motor I never ever had any oil burning issues of any sort. When I upgraded my block to a M54B30 motor I instantly inherited oil consumption issues. I'm now burning about a quart every 800 miles and I change my oil religiously every 7.5k. I ordered a four pack of MOA for my engine using the link provided. Additionally, I found that when me motor is low on coolant I seem to burn more oil. Don't know the direct correlation at the moment but I will keep the forum posted.
