AMSOIL OE 5W-30 100% SYNTHETIC MOTOR OIL

AMSOIL OE 5W-30 100% Synthetic Motor Oil delivers full-synthetic engine protection purpose-built for modern gasoline engines with turbochargers and direct injection. It is formulated to go the full OEM-recommended drain interval while providing wear protection that significantly exceeds industry standards.

Today's engines are smaller, hotter, and under more stress than ever. Turbocharged, gasoline direct injection (GDI) engines produce extreme heat and cylinder pressures that push conventional and lower-quality synthetic oils past their limits. These conditions accelerate oil breakdown, promote sludge formation, and increase the risk of low-speed pre-ignition (LSPI), a damaging combustion event that can crack pistons and bend connecting rods. The oil you run needs to handle all of it without falling short before the next drain interval.

47% MORE WEAR PROTECTION THAN THE GM DEXOS1 GEN 2 SPEC REQUIRES
The Peugeot TU3M Wear Test (CEC L-38-A-94) is the benchmark for anti-wear performance under the GM dexos1 Gen 2 specification. A four-cylinder test engine runs for 100 hours under extreme, wear-inducing conditions, and the resulting camshaft wear is measured in microns. AMSOIL OE 5W-30 delivered 47% more wear protection than the maximum allowable limit in this test. That margin matters in engines like the GM 2.7L Turbo, Ford 2.3L EcoBoost, and other small-displacement powerplants where lower-viscosity oils and high specific output put serious demand on the oil film protecting cams, pistons, and bearings.

100% PROTECTION AGAINST LOW-SPEED PRE-IGNITION
LSPI is one of the most destructive phenomena in modern turbocharged GDI engines. The fuel-air mixture ignites spontaneously before the spark plug fires, producing extreme pressure spikes that can destroy pistons and connecting rods. AMSOIL OE 5W-30 achieved zero LSPI events across five consecutive runs of the engine test required by the GM dexos1 Gen 2 specification. That is 100% protection in a test specifically designed to evaluate an oil's ability to prevent LSPI. For vehicles like the Chevy Silverado 1500 with the 2.7T, Ford Escape with the 1.5L EcoBoost, or Honda CR-V 1.5T, this is a critical performance requirement.

FIGHTS SLUDGE AND DEPOSITS IN HIGH-HEAT ENGINES
Synthetic base oils resist chemical breakdown far more effectively than conventional base stocks. AMSOIL OE 5W-30 is built on a 100% synthetic formulation paired with detergent and dispersant additives that actively suspend and remove harmful contaminants. This keeps oil passages clean, prevents sludge accumulation, and helps maintain proper oil flow to critical components. In engines that run hot, like turbocharged four-cylinders operating under load, deposit control directly affects long-term reliability and oil consumption.

PROTECTS ACROSS THE FULL TEMPERATURE RANGE
AMSOIL OE 5W-30 stays fluid in cold temperatures for easier cold starts and rapid lubrication of components during the critical first seconds after startup. Its pour point of -44°C (-47°F) means it flows readily even in harsh winter conditions. On the high end, a flash point of 220°C (428°F) and strong resistance to thermal thickening help the oil maintain its protective film and viscosity stability in sustained high-temperature operation. This makes it a solid synthetic 5W-30 motor oil for vehicles driven year-round in varying climates.

IMPROVES FUEL ECONOMY AND SUPPORTS EMISSIONS SYSTEMS
AMSOIL OE 5W-30 is API-licensed and carries the Resource Conserving designation, which means it has passed fuel economy testing standards set by the American Petroleum Institute. It is also formulated to be compatible with modern emissions-control hardware, promoting proper catalytic converter function and supporting low exhaust emissions over the life of the oil.

Specifications and Compatibility
AMSOIL OE 5W-30 is recommended for applications requiring any of the following specifications: API SP (Resource Conserving), SN PLUS, SM; GM dexos1 Gen 3 (supersedes dexos1 Gen 2, LL-A-025, 6094M, and 4718M); ACEA A1/B1, A5/B5; Chrysler MS-6395; Ford WSS-M2C946-B1, WSS-M2C946-A, WSS-M2C929-A, WSS-M2C961-A1; Honda HTO-06; ILSAC GF-6A, GF-5, GF-4.

It is compatible with other synthetic and conventional motor oils. However, mixing oils will shorten the life expectancy and reduce performance benefits. Aftermarket oil additives are not recommended.

Service Life
In gasoline-fueled vehicles, AMSOIL OE 5W-30 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.
