Brad Penn Penn Grade 1 40W Partially Synthetic Motor Oil - 009-7140
Formulated with the unique cut from our Penn-Grade stocks, this heavy viscosity straight-grade motor oil is designed to provide excellent protection for street and competition engines. Its superior film strength, highly effective detergency package and foam inhibitors make it an optimal lubrication choice for muscle car/hot rod enthusiasts. The increased ZDDP provides outstanding antiwear/antiscuffing protection for engines with older style push rods as well as those employing flat tappet cams. Excellent option for vintage car lubricant and air-cooled applications where a mono-grade viscosity is preferred.
