AMSOIL OE 10W-30 100% Synthetic Motor Oil is a fully synthetic gasoline engine oil engineered for engines that specify an SAE 10W-30 viscosity, including many trucks, SUVs, and older cars where the owner manual calls for that grade. The formulation meets API SQ (Resource Conserving), API SP, and API SN Plus, along with ILSAC GF-7A, GF-6A, and GF-5 service categories, and it is designed for the longer drain intervals recommended by original equipment manufacturers rather than the extended drain coverage of AMSOIL Signature Series. OE 10W-30 is built for mechanics, fleet operators, and drivers who want a true 100 percent synthetic upgrade over conventional oil while following the maintenance schedule printed in the owner manual.
Advanced wear protection for pistons and cams
OE 10W-30 develops a strong fluid film backed by anti-wear additives that further reduce metal-to-metal contact at pistons, cams, and bearings. The formulation provides 47 percent more wear protection than the GM dexos1 Gen 2 specification requires, based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test (CEC L-38-A-94). That wear test runs a four-cylinder engine for 100 hours under aggressive, wear-inducing conditions, and the added margin matters in the high-load environments common to smaller displacement turbocharged engines that often share the same family of OE formulations.
LSPI defense for turbocharged direct-injection engines
Low-speed pre-ignition is the spontaneous ignition of the fuel and air mixture before the spark fires, and it is most damaging in turbocharged gasoline direct-injection engines under low-speed load. OE Synthetic Motor Oil features detergent chemistry built to defend against the event and delivered 100 percent protection against LSPI, with zero LSPI events recorded across five consecutive runs of OE 5W-30 in the LSPI engine test required for the GM dexos1 Gen 2 specification. The same detergent platform carries over to OE 10W-30 to support older turbocharged truck engines that share modern combustion stresses.
Cleanliness across the OEM drain interval
OE 10W-30 uses a pure synthetic chemical structure that naturally resists oxidation, paired with detergent and dispersant additives that suspend soot, sludge, and varnish so the oil filter can capture them. The combination keeps oil passages clear and pistons clean over the full OEM-recommended drain interval, reducing the risk of stuck rings and oil consumption in higher-mileage engines. Synthetic base oils also resist chemical breakdown at the elevated temperatures common to towing, hauling, and stop-and-go traffic, so the oil holds its protective qualities longer than a comparable conventional 10W-30.
Heat control, cold-start flow, and viscosity stability
Hotter-running engines and tighter clearances both demand stable viscosity. OE 10W-30 carries a viscosity index of 155 and a high-temperature high-shear viscosity of 3.3 cP at 150 C in ASTM D5481, supporting consistent oil film thickness at peak operating temperatures. Cold cranking viscosity of 3890 cP at minus 25 C in ASTM D5293 supports faster oil flow to bearings on cold mornings, while a pour point of minus 40 C keeps the oil mobile in winter storage. A NOACK volatility of 4.1 percent in ASTM D5800 reduces evaporative oil loss, which helps limit deposit formation in turbochargers and on intake valves.
Fuel economy, emissions hardware, and OEM specifications
OE 10W-30 is licensed by the American Petroleum Institute and earns the API Resource Conserving designation, supporting fuel-economy targets common to modern OEM specifications. The chemistry is engineered to be friendly to catalytic converters and oxygen sensors so emissions hardware reaches its designed service life. The 10W-30 grade is suitable for applications that call for API SQ (Resource Conserving), SP, or SN Plus, along with GM 6094M and 4718M, Chrysler MS-6395, Ford WSS-M2C205-A, and ILSAC GF-7A, GF-6A, or GF-5.
Recommended applications and service intervals
OE 10W-30 is intended for gasoline-fueled passenger cars, light trucks, and SUVs that specifically call for an SAE 10W-30 viscosity and one of the service categories listed above. It is a direct synthetic replacement for vehicle manufacturer-branded 10W-30 conventional and semi-synthetic motor oils.
Normal and severe service: follow the drain interval stated by the vehicle manufacturer or indicated by the oil life monitoring system, and change the oil filter at every oil change.
Engines that have been modified, raced, or run on alternative fuels such as E85, CNG, or propane should follow the vehicle builder's recommendations rather than the OEM service schedule.
Outside the United States and Canada, follow the vehicle manufacturer's recommended drain interval.
OE 10W-30 is not intended for engines that specifically call for a different SAE grade. Match the right viscosity for the vehicle with the AMSOIL Vehicle Lookup Guide.
OE 10W-30 is compatible with other synthetic and conventional motor oils, but mixing shortens oil life and reduces performance benefits, and extended drain intervals are not supported when oils have been mixed. Aftermarket oil additives are not recommended. AMSOIL Oil Filters pair well with OE 10W-30 for normal OEM-interval service.

Order AMSOIL OE 10W-30
OE 10W-30 is available as a single quart bottle (product code OETQT-EA), a case of 12 quarts (OETQT-CA), a 55 gallon drum (OET55-EA), and a 275 gallon tote (OET27-EA). Using AMSOIL synthetic lubricants does not void a new vehicle or equipment manufacturer warranty, and all AMSOIL lubricants and filters are covered by the AMSOIL Limited Warranty. Confirm the correct viscosity with the AMSOIL Vehicle Lookup Guide, review where OE fits against Signature Series and XL in the Car Oil Guide, then order AMSOIL OE 10W-30 100% Synthetic Motor Oil.
AMSOIL OE 10W-30 is a 100 percent synthetic gasoline motor oil for cars, trucks, and SUVs that call for an SAE 10W-30 viscosity in the owner manual. It is positioned as a value-tier synthetic that follows the longer drain intervals recommended by the vehicle manufacturer rather than the extended drain intervals supported by AMSOIL Signature Series.
Is AMSOIL OE 10W-30 a true full synthetic?
Yes. OE 10W-30 is a 100 percent synthetic motor oil. It uses synthetic base oils paired with a detergent, dispersant, and anti-wear additive package designed to meet the API and ILSAC service categories printed in modern OEM owner manuals.
What is the difference between AMSOIL OE and Signature Series 10W-30?
OE and Signature Series are both 100 percent synthetic, but they target different service intervals. OE 10W-30 is built for the OEM-recommended drain interval or the oil life monitoring system indicator. Signature Series uses a heavier additive treatment and is rated for extended drain service well beyond the OEM interval. OE is the right pick when the goal is a synthetic upgrade at the OEM schedule. Signature Series is the right pick when the goal is to stretch the drain interval safely.
Which specifications does OE 10W-30 meet?
OE 10W-30 is suitable for applications that require API SQ (Resource Conserving), API SP, or API SN Plus, along with GM 6094M, GM 4718M, Chrysler MS-6395, Ford WSS-M2C205-A, and ILSAC GF-7A, GF-6A, or GF-5. The owner manual should list one of these service categories before the oil is installed.
How long can OE 10W-30 stay in service?
In gasoline-fueled vehicles, OE 10W-30 is designed for the drain interval stated by the vehicle manufacturer or indicated by the oil life monitoring system. The oil filter should be changed at every oil change. Owners who want longer drain intervals should look at AMSOIL Signature Series instead.
Does OE 10W-30 protect turbocharged engines?
Yes. The detergent chemistry that OE Synthetic Motor Oil shares across viscosities delivered 100 percent protection against low-speed pre-ignition in the LSPI engine test required for the GM dexos1 Gen 2 specification, based on testing of OE 5W-30. The 10W-30 viscosity is suited to older turbocharged truck and SUV engines that specify an SAE 10W-30 oil.
Will using OE 10W-30 void a new vehicle warranty?
No. Using AMSOIL synthetic lubricants does not void a new vehicle or equipment manufacturer warranty, and all AMSOIL lubricants and filters are covered by the AMSOIL Limited Warranty.
