The PennGrade 1® Legacy.

Based in Lebanon, Ind., our company has Indiana roots as deep as the traditions and values of the “Hoosier” state. The D-A Lubricant Company has been the proud manufacturer of quality lubricant products since 1919. Today, the D-A Lubricant Company includes the brands PennGrade®, PennGrade 1® as well as D-A Lubricants.

PennGrade® Motor Oil is built from the legacy of PennGrade 1® High Performance Motor Oil, or “The Original Green Oil®”. It is the same unique base oil cut and specially selected high-zinc, high-phosphorus formulation that’s been known and trusted by high-performance engine builders and vehicle owners for decades.

Performance Proven

While the name and look have changed, the performance you have come to know and trust has not. “The Original Green Oil®” is still alive and thriving. And our tests prove it.
