2. AMSOIL Saves Money for Long-Distance Commuter
Matt Marshall was stationed at Warren Air Force Base in
Cheyenne, Wyo. until August 2000 when he was transferred
to Buckley Air Force Base in Denver, Colo. Rather than up-
rooting his family of four, Marshall decided to make the
commute to Denver from his home in Cheyenne, a round-trip
of 230 miles. Marshall was putting approximately 50,000
miles on his car per year. His first commuter car lasted about
two years and 100,000 miles. Marshall was using conven-
tional petroleum motor oil at the time, and the engine blew
on one of his trips to Denver. In 2002, Marshall replaced the
car with a 1999 Saturn that had 30,000 miles.
“I told him if he didn’t want to be replacing cars every two
or three years he needed to use AMSOIL,” said Marshall’s
father-in-law, Greg Norman. Norman, an AMSOIL Dealer, set
Marshall up with some AMSOIL Synthetic 10W-30 Motor Oil
and an AMSOIL Ea Oil Filter.
“Five years later, the odometer shows over 280,000 miles
