You almost brought up a little post traumatic stress syndrome with your mention of Amalie. "Amalie better than it has to be", if I remember correctly. Just about the waxiest stuff going I think. Had a 69 Pontiac at one time, original owner ran only Amalie. The valve train, both banks was completely encased in wax. Took a long time to clean, scraping, fuel oil and many changes, but eventually got her clean.
