I have a 2021 Mazda Cx-5 turbo, 36k, that had the valve stem guide/oil burn issue and only run synthetic oil now but was wondering if the 505 ast treatments would add longevity to the engine. Thank you and keep the great content coming.

If you have worn valve guides causing oil to burn nothing is going to help the situation short of a proper repair.
Also, for future reference please put your question in the body of your post, not the title which is meant for a short description. Thank you. (Title edited.)
