Synthetic Motor Oil will increase the longevity of a motor and its components. It contains 2 basic components,
base stocks and additives. What makes a Good Synthetic Engine Oil is the quality of these
components which will determine the life of your drive train. Below is a breif explanation of these
The base stock
comprises the largest portion of the oil. It lubricates internal engine components, disperses heat and allows
piston rings to seal.
Motor oil base stocks can be composed of petroleum, man made materials or a combination of synthetic and
petroleum called synthetic blend.
A petroleum base stock is made up of many different oil parts that make the final product. Petroleum molecules are
normally long carbon chains that can be sensitive to the stress of heat and “boil off” at relatively low
Engine heat breaks apart these molecular chains, making the properties of the oil different, such as viscosity of
the motor oil.
High Quality Synthetic motor oil base stock molecules are uniformly shaped, helping them resist the stress of heat.
Because these high quality synthetic engine oils are built of these evenly shaped molecules, they have a low “boil
off” rate and their physical components, like the viscosity, do not allow the change to take place.
The various chemicals
that comprise a motor oil’s additive system provide anti wear and foam, rust and deterioration protection,acid
neutralization, viscosity maintenance, detergency and dispersancy properties. Additives help modern motor oils meet
the increasing demands of today’s high-tech engines.
Synthetic additive quality differs throughout the luricant industry, ranging from a bare minimum with some oils to
comply with certain requirements, to exceptionally high quality motor oils, such as AMSOIL motor oils..

IMPROVEMENTS IN OIL
Synthetic Motor oil quality has changed quit a bit in the past 40
years, and tough demands on lubricants in todays motor designs call for oils that meet stringent
requirements. Differences in an oil’s ability to meet these requirements determine which service
classification and viscosity grade it may receive.
Viscosity of an oil refers to flow and is the most important quality of an
oil. The viscosity of oil varies with changes in temperature and is thin when heated, thickens when its cold.
Quality oil must flow when it's cold to lubricate internal engine parts upon starting, but it must also be
thicker to protect the engine at high operating temperatures.
When an oil is used at a changing temps, as it is in most motors, the change in thickness should be as small as can
The measure of an oil’s thickness change is called the Viscosity Index (VI) number) as the number gets higher, you
need the smallest viscosity adjustment which provides better the oil protection for the engine.
The number does not tell the actual thickness or thinness of the oil in high and low temp variants; it represents
the rate of change with temperature adjustment.
Viscosity helpers are viscous chemical additives called polymers or polymeric additives, that decrease the rate at
which oils change viscosity with temperature. Viscosity additives extend a engine oil’s operating temp range and
allow the manufacture of multiple grade or all-weather oils. Cheaper quality viscosity improvers, unfortunately,
lead to metal shearing.
AMSOIL Lubricants consist
of High Quality synthetic Motor oil and the top tier of synthetic lubrication ... AMSOIL Synthetic Motor Oil dramatically outperform regular petroleum motor oils.
Synthetic lubricants are man made, synthesized lubricants consisting of 100 percent PAO Basestock Technology,
and maybe made for every lubricating need you have. The consistancy of synthetic lubricants promote
superior lubrication and friction reduction, which in turn assists in superior heat control, wear control
and energy efficiency. This uniformity also helps synthetics maintain their viscosity in high-temperature
operations, which also helps superior wear control. Because they are made up from pure chemicals,
synthetic lubricants contain no contaminants or molecules that do not assist in the lubrication. Synthetic
Lubricants contain no paraffin or wax as do old school lubricants.
Why AMSOIL Synthetic Motor
Oil? High quality synthetic motor oil reduces friction, heat and wear for maximum
power, performance and fuel efficiency. Resistant to high temperature burn off, chemical breakdown and sludging
keeping engines cleaner. Provides low temperature pouring for fast, dependable winter starts and
cold engine protection. Exceed the most demanding world-wide performance standards and meet as well as
beats warranty requirements for all domestic and imported passenger car engines, both turbo charged and non
turbo charged. AMSOIL Signature Series high quality motor oil provide up to 25k-mile or 1-year drain
intervals. Compare Amsoilto other oils in an independant study.

AMSOIL Signature Series Line (25 k mile/1 yr drain interval)
AMSOIL 0W-20 (ASM), 5W-30 (ASL) and 10W-30 (ATM) Synthetic Motor Oils join AMSOIL Signature
Series 0W-30 to round out the new Signature Series line. Signature Series 0W-30 is now identified by product code
AZO. Product code SSO will be discontinued and is only available while supplies last.
In addition to being reformulated to meet the latest API SN Resource Conserving and ILSAC GF-5
industry specifications, the new Signature Series line features all-new packaging and represents the very best
motor oils AMSOIL has to offer, allowing motorists to take advantage of maximum extended drain intervals. In the
interest of consistency and clarity within the Signature Series line, all four 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). Click to see 25 k mile oil page.
AMSOIL XL Extended Life Synthetic Motor Oils
(10 k mile/6 mo drain interval)
AMSOIL XL Extended Life Synthetic Motor Oils provide better wear control, high- and
low-temperature protection and increased fuel economy compared to conventional oils. Formulated with extended-drain
boost technology, AMSOIL XL Synthetic Motor Oils provide superior performance for up to 10,000-miles/six
months, or longer when recommended in owner’s manuals or indicated by electronic oil life monitoring
systems. Click here to See all the 10k mile oils.
