Which AMSOIL Products Are Recommended
For Your Vehicles?
Driving Habits Affect Synthetic
Motor Oil Drain Intervals
important to adjust drain intervals according to normal and
severe service recommendations.
Driving habits and the work demanded from vehicles vary greatly.
During the week, my old Suburban gets me to work and back
over my 24-mile commute; on the weekend, when I'm lucky,
I drive 180 miles over to Eagle River, Wis. to enjoy some
fishing. Occasionally I drive down to Madison, Wis. to visit
my daughter at college, which puts me on the road for a minimum
of 10 hours in two days. So how severe are my driving conditions?
A daily commute, some light towing and some highway driving
seem harmless to me. When I actually break down the miles
or hours I put on the Suburban, 80 percent of the miles I
log are from workweek commuting; I don't get out fishing more
than five or six times a year. With drain interval recommendations
dependent on classification of "normal" or "severe"
service, determining when to change oil can be more difficult
than it seems.
is defined by AMSOIL INC. in the Product Recommendation and
Drain Interval Guide (G1490) as, "Personal vehicles frequently
traveling greater than 10 miles at a time and not
operating under severe service." AMSOIL INC. defines
severe service in gasoline applications as, "Turbo/supercharged
engines, commercial or fleet vehicles, excessive engine idling,
use of AMSOIL engine oil in vehicles with more than 100,000
miles without prior regular use of AMSOIL engine oil, daily
short-trip driving less than 10 miles (16km), frequent towing,
plowing, hauling or dusty-condition driving."
for diesel engine applications is defined as "extensive
engine idling, daily short-trip driving less than 10 miles
(16km) or frequent dusty-condition driving." The list
of driving habits denoting severe service in diesel applications
is shorter because diesel engines are built for working conditions
and diesel combustion by-products have less of an effect on
oil than gasoline combustion by-products.
and excessive idling are especially hazardous to
engine operation, so it is vital for vehicles like taxi cabs to pay attention to engine hours
in addition to miles on engine oil. As indicated by the data
displayed in the table above, an engine with low miles but
high hours may still be operating under severe conditions.
A vehicle traveling
primarily on-highway accumulates 15,000 miles in only 313
hours. A taxi traveling the same distance accumulates over
1,000 hours on the oil. Because a taxi drives at very low
speeds and idles excessively, the hours on the engine
oil can be five times greater than that of a vehicle moving
at high speeds for extended periods of time. A vehicle in
stop-and-go traffic takes over 700 hours to accumulate 15,000
miles. Engine hours are an important factor to consider when
discussing the severity of service.
During short trips
(less than 10 miles), a vehicle's engine oil spends
a relatively small amount of time at actual operating temperature;
this is especially true in colder climates. Frequent starts
and excessive idling cause fuel to build up in the oil sump.
Fuel dilution causes a decrease in motor oil viscosity, which
can create abnormal wear by reducing the protective barrier
of oil. Water also accumulates in engines that don't spend enough time
at operating temperature. Water can initiate breakdown of
the oil and result in a sludgy mess if sufficient quantities
are present long enough.
puts a different strain on engine oil. When an engine is operating
under heavy load, oil temperatures can increase significantly,
which promotes oxidation. As temperatures increase, engine
oil reacts with air, and oxygen molecules attach to the base
oil chain making it heavier and thicker. This reaction causes
decreased oil pump-ability. Excessive oxidation causes sludge
and other deposits accumulating in the engine. This is one
of the primary reasons for reduced drain intervals under this
severe-service condition in gasoline applications.
motor oils - Signature Series in particular - are designed
for extended drain intervals beyond OEM recommendations. The
example based on my own driving habits confirms that my once-per-year
oil change with Signature Series 5W-30 Synthetic Motor Oil
is perfectly acceptable. I commute 24 miles a day, haul the
boat five or six times a year and make a couple of long trips
to see my daughter; I am not over-stressing my engine. It's
important to examine your driving habits and conditions to
ensure your vehicle is receiving the best protection possible.

synthetic motor oils are formulated to surpass engine test
specifications, offering protection far greater than competing
motor oils for extended drain intervals. Most synthetic oil
manufacturers make no claim to extended drain intervals, deferring
to the maintenance schedule provided by the vehicle manufacturer.
With its unparalleled oil and warranty program, AMSOIL offers
consumers unprecedented protection and economics.
More than 20 years
ago, AMSOIL began using the NOACK volatility test as a comparison
tool and measurement of quality. Back then, nearly every oil
tested side-by-side with AMSOIL synthetic motor oils failed,
and those that passed barely squeaked by. Other oil companies
paid no attention to NOACK results until Ford Motor Company
made it a requirement for service fill oils, validating what
AMSOIL had said all along.
NOACK Volatility Test
Volatility Test determines the evaporation loss
of lubricants in high temperature service. The more
motor oils vaporize, the thicker and heavier they become,
contributing to poor circulation, reduced fuel economy
and increased oil consumption, wear and emissions. AMSOIL
Synthetic Motor Oil resists high temperature volatization
better than other motor oils. AMSOIL Synthetic Motor
Oil maintains peak fuel efficiency and reduces oil consumption
