AMSOIL, OE 5W-40 Fully Synthetic Engine Oil, Universal Fit

AMSOIL OE 5W-40 Fully Synthetic Engine Oil

AMSOIL OE Synthetic Motor Oil is specifically formulated for enthusiasts seeking maximum engine protection and peak performance. Engineered for the high-stress environments of modern, smaller-displacement engines, this 100% synthetic oil provides advanced wear control, keeps internal components clean, and ensures your vehicle remains reliable under extreme operating conditions. Its uniform molecular structure allows for easier starts and immediate oil pressure, reducing the friction that occurs during the first few seconds of engine operation.

Features

• Advanced Wear Protection: Delivers 47% more wear protection than required by industry standards, safeguarding critical parts like pistons and camshafts.
