HAWN PRENATT OF KENMORE, NY thoroughly researched synthetic oils. After doing his
own comparison of product selection and performance, Prenatt decided AMSOIL was the
ticket, hands down.
In May 2004, Prenatt bought a 1997 Pontiac Firebird with 79,000 miles on it. Before
switching to to AMSOIL, Prenatt had trouble starting the vehicle in fall and winter.
"Before switching over to AMSOIL, I was using whatever brand of oil that the dealership
put in my car," said Prenatt. "Whatever the brand was, it surely did not hold up against
In October 2004, Prenatt installed AMSOIL 10W-30, an AMSOIL filter, Engine Flush,
Bosch Premium +4 Spark Plugs and Wires, and AMSOIL Engine Coolant.
"After the engine flush, oils change and spark plug upgrade, start-ups during cold
weather are easy," said Prenatt.
Prenatt reports that his Firebird drives more smoothly and has more horsepower than
ever before. Prenatt also was impressed with how much cooler the engine runs after
switching to AMSOIL products. "I had an immediate performance increase in my car, thanks
ato AMSOIL and Bosch products," said Prenatt.
