AMSOIL OE 5W-20 100% SYNTHETIC MOTOR OIL

AMSOIL OE 5W-20 100% Synthetic Motor Oil delivers full-synthetic engine protection at an exceptional value for cars and trucks running modern engine technology, including turbochargers and gasoline direct injection. It is built to go the full OEM-recommended drain interval without compromise.

Today's engines are smaller, work harder, and run hotter than ever. Turbocharged, direct-injected engines like the Ford 2.7L EcoBoost, GM 5.3L V8, and Honda 1.5T produce extreme heat and combustion pressures that conventional oils simply cannot handle over a full drain interval. Low-viscosity 5W-20 oil has to maintain its protective film under those conditions while also flowing quickly at startup in cold weather. The wrong oil, or the wrong formulation, leads to accelerated wear, sludge buildup, and potential LSPI damage.

47% MORE WEAR PROTECTION THAN THE GM DEXOS1 GEN 2 STANDARD REQUIRES
The Peugeot TU3M Wear Test (CEC L-38-A-94) is a 100-hour engine test that subjects motor oil to extreme, wear-inducing conditions. It is a required test for GM dexos1 Gen 2 certification. AMSOIL OE Synthetic Motor Oil delivered 47% more wear protection than the maximum allowable wear limit in this test. That kind of margin matters in engines like the Chevy Silverado 5.3L, Ford F-150 2.7L EcoBoost, and Toyota Camry 2.5L, where camshaft and piston wear directly affect efficiency, power output, and long-term reliability.

100% PROTECTION AGAINST LOW-SPEED PRE-IGNITION
LSPI is a serious threat in turbocharged, direct-injected engines. It occurs when the fuel-air mixture ignites before the spark plug fires, generating destructive pressure spikes that can crack pistons and bend connecting rods. AMSOIL OE 5W-20 achieved zero LSPI events across five consecutive tests in the engine test required by the GM dexos1 Gen 2 specification. If your vehicle runs a turbocharged GDI engine, like the Ford EcoBoost, GM Ecotec, or Honda VTEC Turbo, this is the kind of LSPI protection you need from your synthetic 5W-20 motor oil.

KEEPS ENGINES CLEAN AND FREE OF SLUDGE
AMSOIL OE is formulated with 100% synthetic base oils that naturally resist chemical breakdown at high temperatures. That resistance translates directly to fewer deposits on pistons, valves, and turbocharger components. Detergent and dispersant additives suspend and remove harmful contaminants rather than letting them settle into sludge. For engines like the Toyota 2GR-FE, Chrysler Pentastar 3.6L, or Honda K20C, clean internals mean consistent oil flow, proper ring sealing, and reliable performance over the full drain interval.

PROTECTS ACROSS THE FULL TEMPERATURE RANGE
Synthetic base oils give AMSOIL OE a uniform molecular structure that stays fluid in cold temperatures for easier cold starts and rapid lubrication. At high temperatures, it resists thinning and thermal breakdown to control deposits, prevent oil thickening, and limit oil consumption. The 5W-20 viscosity flows quickly on a -20°F morning in Minnesota and holds up under sustained high-rpm driving in summer heat. This makes it a strong fit for daily drivers, commuter vehicles, and fleet trucks that operate year-round in variable climates.

FUEL ECONOMY AND EMISSIONS SYSTEM COMPATIBILITY
AMSOIL OE 5W-20 is API licensed and carries the Resource Conserving designation, meaning it has passed fuel economy testing beyond the baseline API SP requirement. It is also formulated to be compatible with modern emissions-control systems, promoting proper catalytic converter operation and supporting low exhaust emissions over the life of the oil.

Specifications and Compatibility
AMSOIL OE 5W-20 (OEM) meets the following specifications: API SP (Resource Conserving), SN PLUS, SM; GM dexos1 Gen 3 (supersedes dexos1 Gen 2 and 6094M); ACEA A1/B1; Chrysler MS-6395; Ford WSS-M2C945-B1, WSS-M2C945-A, WSS-M2C930-A, WSS-M2C960-A1; ILSAC GF-6A, GF-5, GF-4.

It is compatible with other synthetic and conventional motor oils. Mixing with other oils will, however, shorten the life expectancy and reduce the performance benefits of AMSOIL OE. Aftermarket oil additives are not recommended.

Service Life
AMSOIL OE Synthetic Motor Oil is recommended for the oil change intervals stated by the vehicle manufacturer or as indicated by the vehicle's oil life monitoring system. Change the oil filter at every oil change.
