MOTOR OILS RECOMMENDED FOR CLASSIC CARS
“PennGrade 1 High-Performance Engine Oils Rich in Zinc and
Phosphorous Are What You Should Be Using in Your Triumph or
MG Sports Car”
Oils manufactured for new cars today are not
appropriate for classic car engines with flat valve
tappets and high valve-spring pressures.  Classic car
engines, such as those fitted to Triumph and MG
sports cars, need zinc and phosphorous to protect
high-wear components such as flat valve tappets and
cam lobes.  Zinc and phosphorous were shown to
damage catalytic converters in modern cars, and the
car manufacturers worked with major oil refineries to
remove them from the oils commonly available at
auto parts stores and service garages.
PennGrade 1 engine oils are produced from
Pennsylvania Grade Crude Oil, which has superior
characteristics for refining into engine lubricants.
All PennGrade 1 oils include a ZDDP additive which
provides the zinc and phosphorous required for
classic engines.  PennGrade 1 oils are refined at a
very special address on Kendall Avenue in Bradford,
located near the northern border of Pennsylvania
with New York.  Kendall, Amalie, and Wolf's Head
oils were manufactured there, and TRF is proud to
offer PennGrade 1 oils to our customers, as
Pennsylvania has always been famous for high-
quality engine lubricants.
In these photos, Isaac Lynn, age 3, Brad Lynn's son and grandson of Bill
Lynn, is working on the brakes on the TR6 and changing the oil in the TR2.
