EVIN HARRINGTON OF STRATHAM, NH began
using AMSOIL Synthetic Motorcycle Oil
this year and was eager to tell others of his
"I am a new customer to AMSOIL," Harrington
said. "After several years of riding

Harrington purchased AMSOIL 10W-40
Synthetic Motorcycle Oil for his 2002
Honda CBR954RR. "I've used Honda-branded

After he installed AMSOIL motorcycle oil,
Harrington was surprised at the differences
he experienced in his bike. "I've
noticed three key improvements with the
use of AMSOIL Synthetic Motorcycle Oil,"
he said. "The CBR954RR has always had
some noticeable valve clatter at idle. Using
AMSOIL motorcycle oil, the valve clatter
at idle has disappeared. There is no more
clatter at idle."
A technician told Harrington when he bought
the bike nearly 10 years ago that shifting
would be "clunky as a normal condition."
According to Harrington, the wet-clutch
lubricity has improved shifting smoothness
"AMSOIL Synthetic Motorcycle Oil for
wet-clutch applications has eliminated the
shifting clunkiness and the accompanying
noise when shifting," Harrington said.
The motorcycle also ran cooler.
"The motorcycle cooling system temperature
ran consistently at 187 to 194 degrees
when cruising at 65 MPH for extended
periods during 75-degree weather while
running GN4 or HP4 oils," Harrington said.
"I've noticed a repeatable temperature
reading of six to nine degrees lower under
the same degree [temperature] day and

to 189 degrees consistently."
AMSOIL Synthetic Motorcycle Oil has made
noticeable improvements in the Honda's
"I'm convinced that AMSOIL motorcycle
oil is clearly the renewal required for my
high-performance motorcycle and superior
to other commercially available products,"
Harrington said. "No other oil will be used
in my CBR954RR unless AMSOIL introduces
an even better product that exceeds the
practical application and test results of the
AMSOIL 10W-40 Synthetic Motorcycle Oil.
