PennGrade Motor Oil is built from the legacy of PennGrade 1 High Performance
Motor Oil, or "the Original Green Oil." PennGrade 1 is cut from Pennsylvania
Grade Crude Oil from the Bradford Oil Field in Bradford, Pennsylvania, where
it was first extracted in 1859. The oil has a unique green color and the
ability to stick and cling to metal objects, offering full film strength to
the customer. Its enhanced levels of zinc and phosphorous protect vital
engine components, and it has been the first choice of engine builders and
equipment manufacturers for decades.
PennGrade 1 is manufactured at what was once known as the Bradford Refinery,
which was later renamed the Kendall Refinery. Witco Chemical acquired the
refinery in 1966, and produced both the Kendall and Amalie oil lines. Both
lines became very popular with extremely loyal consumers. In 1997 Witco
Chemical sold the refinery and its existing inventory to American Refining
Group (ARG). While the refinery was still making oil, it had no name to sell
it under. From this scenario, ARG renamed the product Brad Penn Motor Oil
and tasked its salespeople to sell the oil within only 150 miles of the
As time went on, the customer base swelled outside of Pennsylvania and
clamored for a high performance oil to go along the trusted Brad Penn line.
After recognizing the extremely high demand and interest from engine
builders and racers ARG began selling PennGrade 1 High Performance Oil,
which was the same green oil this loyal group had been buying under the
Kendall and Amalie names for many years. PennGrade 1 sales grew
exponentially when distributors offered it to their customers because of its
rich history of consistent quality at a fair price point.
