EALER BRAD WALTHOUR OF SUNBURY, OHIO speaks from
experience when he talks about the qualities and
benefits of AMSOIL lubes and filters.
Walthour became a Dealer several years ago when
the recommendations of an AMSOIL Dealer saved him
the cost of an engine rebuild in his 2003 Dodge Ram
3500 dually with the Cummins 5.9L high-output turbo
diesel engine and six-speed manual transmission with
a 4:10 gear ratio.
"At approximately 200,000 miles I noticed a strong
fuel odor and light gray smoke emitting from the tailpipe
while idling," Walthour said. "I could smoke out six guys
on Harleys at a red light; not exactly a good situation
to put yourself in."
After taking the truck to three different shops,
spending money on parts and getting recommendations
that included an expensive engine rebuild,
Walthour’s friend, AMSOIL Dealer Walt Conrad, suggested
Conrad, an AMSOIL Dealer of more than 20 years,
recommended AMSOIL Diesel Concentrate and Cetane
Boost. "He was adamant about this, a genuine believer
in AMSOIL products, and his recommendation was
certainly a lot less expensive," Walthour said.
The dually has the original 35-gallon fuel tank with
an additional 80-gallon fuel tank that Walthour installed
in the bed behind the cab.
"At 222,000 miles I began using those two products
in my truck at every other fuel fill, and I installed AMSOIL
15W-40 Heavy Duty Diesel and Marine Synthetic Motor
Oil and an AMSOIL EAO80 Oil Filter," he said. "The
smoking began to dissipate and within 10,000 miles,
or approximately one month, the smoking at idle was
eliminated by about 85 percent. What a relief."
At 325,000 miles his mechanic replaced the fuel
pressure relief valve. "Apparently, some leftover fuel in
the old valve was not burning off completely. It was
going straight out the tailpipe, causing the odor and
smoke. Replacing that part eliminated the other 15
percent of the smoke and it hasn’t smoked once since.
That was more than 300,000 miles ago."
The truck is the workhorse for his day job delivering
new recreational vehicles, campers, autos, boats and
horse trailers to dealerships in 48 states. "They range
anywhere from 6,000 pounds to 14,500 pounds gross
vehicle weight," Walthour said. He often hauls in harsh
"I rely solely on AMSOIL products to protect my
investment in a wide range of outside temperatures on
various and challenging terrain," Walthour said. He
uses AMSOIL Cold Flow Improver during the cold
months. "The fuel has never gelled," he said. "The
engine and transmission have never been dismantled,
rebuilt or replaced." He averages 26 mpg at 55 miles
per hour when he’s not towing anything and 11.5 to 14
mpg when towing. He calculates his oil change savings
with AMSOIL products to be $300 a year, which doesn’t
include the added protection against wear and extreme
"I change the oil every four months or 40,000 miles
at a cost of $100 instead of every 10,000 miles at a cost
of $50," Walthour said. "The AMSOIL Ea Oil Filter is
changed every 20,000 miles. Every oil analysis result
has had the same notation, 'oil is suitable for continued
use.' I’m sure many of my trouble-free miles are
because of AMSOIL products."
DODGE WORKHORSE — Dealer Brad Walthour (above) bought
this 2003 Dodge truck new and uses it daily to haul heavy loads to
48 states. AMSOIL products save him hundreds of dollars each
year, as well as provide added wear protection for his hard-working
