Penn Grade 1 15W-40 Oil - 1 Quart

Penn Grade 1 High Performance Oils are formulated using a unique base oil cut, which gives Penn Grade 1 Oils exceptional film strength. This unique base oil causes it to cling tenaciously to engine parts to minimize wear during high engine torque loading and periods of heavily stressed operation such as those experienced during competition. This same oil cling helps prevent dry-start conditions to minimize wear even after extended periods of disuse.

Penn Oils also contain highly effective detergent and dispersant additives to guarantee exceptional engine cleanliness as well as oxidation and foam inhibitors that offer protection against thermal degradation and air entrainment.

In addition to the unique base oil cut, increased concentration of zinc (ZDDP) provides outstanding anti-wear and anti-scuffing protection for engines employing either ‘flat tappet’ or roller cams. Penn Oils have been evaluated by a number of premiere camshaft manufacturers with tremendous success. Many are now recommending Penn Grade 1 Oils to provide outstanding protection.

Due to high concentrations of Zinc Dialkyldithiophosphate (ZDDP), extended periods of use in vehicles equipped with catalytic converters can cause premature catalyst failure.
