Your Oil-Life Monitoring System
Is Not An On-Board Chemist
Monitoring Systems Do Not Actually Measure The Properties
Of Motor Oil.
systems (OLMS) have become more common in the last decade.
The goal of an OLMS is to increase engine oil drain intervals
without risk to the key components the oil is lubricating, which is similar to one of the main goals
of used-oil analysis. But that's where the similarities
end - with the objective. Since most new cars come equipped
with some type of OLMS that can directly contradict AMSOIL-warranted
extended drain interval recommendations, I want to go over
how the systems are designed, how they function and what you
need to know when it comes to extending oil drain intervals.
monitor is a poor description for these systems. A better
name would be oil life estimator. These systems do not monitor
any direct physical or chemical property of used oil;
they only accumulate operational data from the car's
computer and attempt to predict how your driving habits have
impacted the motor oil's viscosity, total base number
(a measure of remaining detergency) and oxidation level. Since
these key properties are not actually measured by an OLMS,
how can it know when there's only 10 percent life left
on an oil? It can't. An OLMS provides a gross estimate
of oil life based on a mathematical model developed using a specific type of oil.
An OLMS takes no
direct measurement of oil viscosity, which is critical in
estimating oil life, nor does it measure TBN to gauge how
much detergent is left to fight acidic combustion byproducts.
There also is no on-board $50,000 gauge to measure the oxidation
level of the oil. If your OLMS actually monitored the properties
of your oil, you would not be able to simply press a couple
buttons and reset your OLMS to 100 percent oil life. If you
are from Missouri and need to test this fact, try it before
your next oil change.
So is your OLMS
useless? Not exactly. These systems are getting better and
do a decent job of convincing drivers to extend oil drain
intervals, helping to break the outdated and wasteful practice
of changing oil every 3,000 miles. But an OLMS cannot tell
the difference between a high-quality synthetic oil and a
run-of-the-mill conventional oil.
The first oil monitors
were mileage based and provided outdated mileage options such
as 3,000 or 5,000 miles. Some cars are still equipped with
these mileage-based indicators.
monitoring systems are engineered with an understanding of
how temperature and load affect oil integrity; extreme temperatures
and engine load are known to shorten oil life. For example,
the GM OLMS penalizes estimated oil life when the engine is
driven in very cold conditions or when the engine is extremely
GM claims most
drivers will be able to achieve between 7,500- and 8,500-
mile intervals; however, some drivers could see longer intervals
if their driving conditions permit. GM says the GM OLMS automatically
adjusts the interval based on engine characteristics, driving
habits and climate. GM also claims the use of synthetic oil
does not extend drain intervals, but does acknowledge using
synthetic motor oil may provide some benefits.
vehicles use an algorithm-based system called the Intelligent
Oil-Life Monitor (IOLM). Ford claims the IOLM can provide
oil drain intervals of up to 10,000 miles, depending on driving
conditions. The Ford IOLM monitors driving conditions such
as engine speed and load, oil and coolant temperature, hours
of op-eration, hours of idle time and the cleaning cycle for
diesel particulate filters, if equipped. Ford engines are
tested using Motorcraft synthetic-blend oils. The IOLM algorithm
is entirely software-based, meaning it does not monitor the
oil's direct chemical or physical quality. Other Ford vehicles
are equipped with a system that does not gather operating
data to calculate oil life; it simply signals an oil change
is necessary every 10,000 miles or one year.
Despite the technological
advances and sophistication of the newer on-board oil-monitoring
sytems, they are still a predictive model and cannot directly
measure key used oil properties nor differentiate between
a high-end synthetic motor oil and an entry-level conventional
product. AMSOIL developed Signature Series Synthetic Motor
Oil and confirmed Its performance in field trials with used-oil
analysis. We used vehicles from several different manufacturers
and ran them in the harshest environments we could find; all
so you can sleep well at night when your OLMS says you need
an oil change and you don't plan on doing so until next spring.

AMSOIL Signature Series
Synthetic Motor Oil
AMSOIL Signature Series Synthetic
Motor Oils are formulated to meet the latest API SN Resource
Conserving and ILSAC GF-5 industry specifications. AMSOIL
Signature Series Oils include 0W-20, 0W-30, 5W-30 and 10W-30
and represent the very best motor oils AMSOIL has to offer,
allowing motorists to take advantage of maximum extended
drain intervals. AMSOIL Signature Series Synthetic Motor
Oils are recommended for drain intervals of up to 25,000
miles/one year, whichever comes first (15,000 miles/one
year in severe service conditions).

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
