Low viscosity Super-D FE 10W-30 leads the industry with its FA-4 formulation. It is proven to deliver up to 2% fuel savings while providing superior wear protection.

The Industry's Strongest Wear Protection

Super-D FE significantly outperforms Mobil Delvac™ Super FE 10W-30 in the DD13 Scuffing Test. And after 92 million miles of on-road testing and multiple engine tear downs, pistons and cylinder liners showed little to no signs of wear.

DD13 Scuffing Test Results

At 200 hours, Super-D FE 10W-30 showed no scuffing. The DD13 Scuffing Test (ASTM D8074) was run at an independent lab using blind samples. This is a fired-engine test with all emissions controls, which runs for 200 hours or until scuffing is detected, whichever comes first.
