BRAD PENN Grade 1 Racing Oils contain the “highest parts per
million” anti-wear zinc formulation of any true racing oil and is
designed for “off road performance” of wide open exhaust, not
government regulated catalytic converters! This unique base oil
causes our Penn Grade 1 racing oil to cling tenaciously to engine
parts to minimize wear during high engine torque loading and/or
periods of heavily stressed operation such as those experienced
during competition. The 20/50, 10/30 and 30w are partial synthetic.
