Each new API group has placed successively lessen phosphorus and zinc boundaries, and thus has established a controversial situation of obsolescent oils necessary for more mature engines, Specially engines with sliding (flat/cleave) tappets. API and ILSAC, which signifies almost all of the planet's major vehicle/motor companies, point out API SM/ILSAC GF-4 is fully backwards appropriate, and it's observed that one of many motor tests essential for API SM, the Sequence IVA, is really a sliding tappet style and design to check specifically for cam don protection.
