When engines wear and accumulate deposits, horsepower and torque fade. Signature Series 100% Synthetic Motor Oil is built to help engines run stronger, longer** – helping to protect against performance loss.

Signature Series 5W-30 was installed in a 2025 Ford* F-150 Raptor* and run through a 125,000-mile test.

Signature Series maintained horsepower and torque throughout the test, even under the elevated stresses of a high-output engine.
