AMSOIL 5W-20 Signature Synthetic Motor Oil
Protects Your Engine
AMSOIL 5W-20 Signature Series Synthetic Motor Oil provides outstanding anti-wear protection. It develops a strong fluid film that keeps metal surfaces separated while its robust anti-wear additives further reduce wear in metal-to-metal contact regions for maximum engine life. In the Sequence IIIG test, which is normally run for 100 hours, AMSOIL Signature Series Synthetic Motor Oil delivered outstanding wear protection for the camshaft and lifters, even after doubling the test interval to 200 hours. For details, see the Double-Length Sequence IIIG Engine Test Technical Study (G3320).
Maximizes Fuel Economy
AMSOIL Signature Series Synthetic Motor Oil is designed to maximize energy efficiency for optimum 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.
Extends Drain Intervals
AMSOIL 5W-20 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 is designed to deliver outstanding engine protection, cleanliness and performance over extended drain intervals. It reduces vehicle maintenance and waste oil.
Keeps Pistons Clean
Excess piston deposits can lead to pre-ignition and engine knocking, which results in lost power, reduced fuel economy and, in severe cases, engine damage. Signature Series’ premium additives and naturally high resistance to extreme heat help keep pistons clean for maximum engine performance. After a double-length, 200-hour Sequence IIIG engine test, Signature Series demonstrated outstanding cleanliness properties and shattered the requirements of a 100-hour test.
Excels in Extreme Temperatures
AMSOIL 5W-20 Signature Series resists thermal (heat) breakdown better than conventional and synthetic motor oils. It is heavily fortified with detergent and dispersant additives to help prevent sludge deposits and keep engines clean. Unlike conventional oils, Signature Series contains no wax, staying fluid in sub-zero temperatures for easier starting, improved oil flow and reduced wear.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. Signature Series resists volatility better than other oils, helping reduce oil consumption and emissions.
AMSOIL 5W-20 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:
5W-20 (ALM): API SN (Resource Conserving), SM…; ILSAC GF-5, GF-4…; ACEA A1/B1; Ford WSS-M2C945-A, WSS-M2C930-A; Chrysler MS-6395; GM dexos1™ (supersedes 6094M) Fortified with detergents that exceed dexos1 sulfated ash specifications.

AMSOIL 5W-20 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 its 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.
Normal Service – Up to 25,000 miles, 700 hours of operation or one year, whichever comes first, in personal vehicles not operating under Severe Service.
Severe Service – Up to 15,000 miles, 700 hours of operation or one year, whichever comes first.
Severe Service: Primarily short trips (less than 10 miles [16 km]); turbo/supercharged engines; commercial or fleet vehicles; excessive idling; first-time use of AMSOIL motor oil in a vehicle with more than 100,000 miles; frequent towing, hauling, plowing or driving in dusty conditions.
Modified engines (non-stock) and those using E85 fuel are excluded from extended drain recommendations.
Change at the vehicle manufacturer’s recommended drain interval outside U.S. and Canada.
AMSOIL Ea® Full-Flow Oil Filters are designed for extended change intervals. With other brands, do not exceed six months or 10,000 miles unless longer intervals are recommended by the vehicle manufacturer.
Check oil regularly to maintain proper fill levels.
AMSOIL Ea® Full-Flow Oil Filters are designed for extended change intervals. They stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Ea Full-Flow Oil Filters.
