SAE 30 High Performance Oil. A lighter straight-grade viscosity oil characterized by its proven protection and performance. Along with its Penn Grade 1 straight-grade counterparts, the Brad Penn Penn Grade 1 SAE 30 High Performance Oil offers excellent film strength and an effective detergency package and is a good choice for the legacy muscle car/street rod. Excellent oil for vintage and air-cooled applications requiring a straight grade oil.
