Extends Drain Intervals
AMSOIL 0W-30 Signature Series Synthetic Motor Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long-drain additive system are inherently stable to resist oxidation and neutralize acids over longer periods. Signature Series Synthetic Motor Oil is designed to deliver the best possible engine protection, cleanliness and performance over extended drain intervals. It reduces vehicle maintenance and waste oil disposal costs.
Maximizes Fuel Economy
AMSOIL Signature Series Synthetic Motor Oil is designed to maximize energy efficiency for improved fuel economy. Unlike conventional oils, its uniform molecular structure helps it flow more freely and reduce friction between metal surfaces. Anti-friction additives are included to further improve energy efficiency.
Reduces Engine Wear
Signature Series Synthetic Motor Oil provides outstanding anti-wear protection. It has excellent viscosity film strength to separate metal surfaces and robust anti-wear additives to further reduce wear in metal-to-metal contact regions for improved engine life.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Signature Series Synthetic Motor Oil exhibits an extremely low volatility rate; it controls volatility-related oil consumption and emissions.
Excels in Extreme Temperatures
AMSOIL Signature Series Synthetic Motor Oil resists thermal (heat) breakdown better than conventional oils. It is heavily fortified with detergent and dispersant additives to help prevent sludge deposits and keep engines clean. And unlike conventional oils, Signature Series Synthetic Motor Oil contains no wax, staying fluid in the coldest winter temperatures for easier starting, improved oil flow and reduced bearing wear.
APPLICATIONS
AMSOIL Signature Series Synthetic Motor Oil is excellent for use in all types of gasoline-fueled vehicles. It is recommended for all domestic and foreign vehicles requiring any of the listed performance specifications:
0W-30 (AZO): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A5/B5, A1/B1; Ford WSS-M2C946-A, WSS-M2C929-A; Chrysler MS-6395N; Suitable as a replacement for GM dexos1™ (supersedes LL-A-025, 6094M and 4718M)
COMPATIBILITY
AMSOIL Signature Series Synthetic Motor Oil is compatible with other conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil's life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL synthetic motor oils.
SERVICE LIFE
AMSOIL Signature Series Synthetic Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline-fueled vehicles as follows:
• Normal Service(3) - Up to 25,000 miles or one year, whichever comes first.
• Severe Service(4) - Up to 15,000 miles or one year, whichever comes first.
• In all non-gasoline-fueled vehicle applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.
*OEM - Original Equipment Manufacturer
(1) Engines operating under modified conditions (non-stock) are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.
(2) Mechanically sound engines are in good working condition and do not, for example, leak or consume excessive amounts of oil, are not worn out, do not overheat, do not leak antifreeze and have properly working emissions control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
(3) Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.
(4) Turbo/supercharged engines, commercial or fleet vehicles, excessive idling, vehicles with more than 100,000 miles without prior continuous use of AMSOIL motor oil, daily short-trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.
AMSOIL Ea full-flow oil filters are designed for extended drain intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea full-flow oil filters.

DRIVEN BY EXCELLENCE
As A.J. Amatuzio neared the end of his 25-year career as an award-winning jet fighter pilot, he set his sights on a new challenge. Knowing that every jet engine in the world used only synthetic oil, he was convinced that the same type of technology would provide tremendous benefits to automotive engines. In the early-1960's he set out on an intense period of research and development.
In 1972 A.J. Amatuzio created AMSOIL INC. and introduced the world's first API qualified synthetic motor oil, AMSOIL 10W-40. But obstacles remained for Amatuzio. The major oil companies were threatened by his advanced technology and, along with the auto manufacturers, refused to acknowledge his revolutionary new product.
Amatuzio persevered. Through sheer determination he began to convince the motoring public that AMSOIL synthetic motor oil was far superior to the conventional petroleum oils they had been using. Then, as consumers caught on by the thousands, the competing oil companies could no longer deny the performance benefits of AMSOIL motor oil. They were forced to follow the AMSOIL lead and, one by one, developed synthetic oils of their own. Amatuzio had humbled an industry.
Today, AMSOIL remains the leader in quality and innovation. A.J. Amatuzio Signature Series Motor Oil is engineered with the world's most advanced synthetic base oils and high-performance additives. This exclusive formulation represents the benchmark in motor oil technology and sets the standard by which all other motor oils are measured.
