Rust and corrosion can cause significant damage to engine components and reduce part lifetimes. Rust inhibitors are oil additives that help prevent this corrosive damage by protecting metal surfaces.
Many rust inhibitors work by adsorbing onto metallic surfaces and forming thin chemical films. These monomolecular layers shield the metal from water and oxygen that cause corrosion. Common rust inhibitor chemistries include carboxylic acids, amines, phosphoric acid esters, and sulfonates.
Rust inhibitors also neutralize acids formed in the oil during engine operation. Acidic oxidation products promote corrosion, so inhibiting their activity helps preserve engine metals. Some additives offer both rust prevention and acid neutralization.
Properly formulated rust inhibitors protect critical parts like bearings, cylinder walls, camshafts, and valves from rust damage. This helps maintain engine performance and longevity despite hot, stressful operating conditions.
