PRODUCT DESCRIPTION
AMSOIL Signature Series 0W-30 Synthetic Motor Oil (SSO) is the industry benchmark in lubrication
technology. Engineered with the world’s finest synthetic base oils and high performance additives,
AMSOIL Signature Series 0W-30 is designed for those who demand the absolute best in motor oil
performance. The exclusive “extended drain” formulation delivers superior engine protection and
maximum fuel economy. AMSOIL Signature Series 0W-30 is a premium grade synthetic motor oil that
exceeds the requirements of modern, high-performance engines and older engines. It replaces other
0W-30, 5W-30 and 10W-30 motor oils and consistently outperforms competitive conventional and
synthetic motor oils.
AMSOIL, the leader in automotive synthetic lubrication, produced the world’s
first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL
The First in Synthetics® to do the best job protecting your engine.
Extends Drain Intervals
AMSOIL Signature 0W-30 Synthetic Motor Oil lasts much longer in service than conventional oils. Its
unique synthetic formulation and long drain additive system resist oxidation and neutralize the
acids that shorten the service life of other oils. AMSOIL Signature Series 0W-30 delivers the best
possible engine protection, cleanliness and performance over extended drain intervals, reducing
vehicle maintenance and waste oil disposal costs.
Maximizes Fuel Efficiency
The lightweight molecular structure of AMSOIL Signature Series 0W-30 Synthetic Motor Oil reduces
energy loss from the “drag” common to high viscosity oils. It is fortified with additives that
enhance its friction-reducing properties to help further improve fuel efficiency.
Reduces Wear
AMSOIL Signature Series 0W-30 Synthetic Motor Oil contains specialized anti-wear technology. Its
durable, high temperature film strength effectively separates metal surfaces to reduce wear even
under the most grueling conditions. Tests prove that AMSOIL Signature Series 0W-30 provides better
protection against wear than other motor oils (see graph). AMSOIL Signature Series 0W-30 helps
engines last longer.
Resists Heat, Reduces Oil Consumption and Emissions
AMSOIL Signature Series 0W-30 Synthetic Motor Oil is thermally stable with a strong resistance to
high temperature volatility (burn-off). It is heavily fortified with detergent and dispersant
additives designed to prevent sludge deposits and keep engines clean. Low volatility and clean
operation reduce oil consumption and emissions.

Provides Outstanding Cold Flow Properties
Unlike conventional oils, AMSOIL Signature Series 0W-30 contains no wax. Its exceptional -60°F cold
flow properties ease starting and reduce bearing wear.
APPLICATIONS
AMSOIL Signature Series 0W-30 Synthetic Motor Oil is recommended for use in gasoline engines,
diesel engines (API CF, ACEA B5) and other applications requiring SAE 0W-30, 5W-30 or 10W-30 with

gasoline engines. AMSOIL combined the industry premier synthetic technology and additives into a
light viscosity formulation that withstands high temperatures and delivers outstanding fuel economy
and cold temperature performance. AMSOIL ASM replaces SAE 5W-20 and is recommended for extended
drain intervals according to AMSOIL service interval guidelines. It delivers long-lasting
performance and protection.
AMSOIL, the leader in automotive synthetic
lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the
extensive experience of AMSOIL “The First in Synthetics” to do the best job protecting your
engine.
Extends Drain Intervals
AMSOIL Synthetic 0W-20 Motor Oil can extend drain intervals far beyond those recommended for
conventional oils. Its unique synthetic formulation and long drain additive system are very stable,
resisting oxidation and neutralizing acids. AMSOIL ASM delivers the best possible engine
protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance
and waste oil disposal costs.
Maximizes Fuel Economy
AMSOIL Synthetic 0W-20 Motor Oil is designed to maximize energy efficiency for improved fuel
economy. Its light viscosity properties reduce drag and its uniform molecular structure helps it
flow more freely to lower friction between metal surfaces. Anti-friction additives are included to
