PennGrade 1 Partial Synthetic High Performance Motor Oil

PennGrade 1 Synthetic 5W30 Racing Oil is a truly versatile, high-performance oil suitable for engines on both on the street and/or the track. Developed to protect, the multi-viscosity grade and synthetic components facilitate cold starting and quicker engine warm-up while reducing internal friction for increased horsepower output. With every quart of PennGrade 1 Racing Oil you can expect:

  • Superior film strength maintains protection even under the most demanding torque applications.
  • The benefit of oxidation and foam inhibitors protect against thermal degradation, providing stability and high-temperature protection.
  • Additional detergent and dispersant additives that aid in engine cleanliness.

With Brad Penn’s many offerings, you can be confident in their lubricants. That’s why we trust them here at Karl Kustoms, in the cars that leave our shop and in every quart we ship. Looking for other oil and lube components? Check out this post to learn about oil pan options for older LS swaps.
