The extreme durability of Signature Series Motor Oil helps
your engine run stronger, for longer. We installed Signature
Series 5W-30 Synthetic Motor Oil in a Ford* F-150* with
a new 3.5L Ecoboost* engine to test its ability to protect
turbocharged direct-injection (TDGI) engines from torque and
horsepower loss during extended drain intervals up to 25,000
miles (40,200 km). Power sweeps were done at the beginning
and end of the test to evaluate horsepower and torque
retention. As the graph shows, Signature Series helped
maintain engine performance throughout the 100,000-mile
(160,934 km) test.
