Phosphorous prolongs the life of your engine by limiting the friction in the engine. As for zinc, it is ideal for older engines because it functions as a performance booster.
Oil Additive Types
- Anti-Foaming Agents: With the chemicals that it contains, it inhabits foam and air bubbles in the engine oil. If the foam bubbles don’t burst, they would speed up the oxidation process which leads to corrosion.
