AMSOIL OE 5W-30 100% Synthetic Motor Oil is a fully synthetic gasoline engine oil formulated to follow the manufacturer-recommended drain interval or the in-vehicle oil life monitor. The 5W-30 grade meets API SP (Resource Conserving), API SN Plus, GM dexos1 Gen 3 (supersedes dexos1 Gen 2, LL-A-025, 6094M, and 4718M), Ford WSS-M2C946-B1, Chrysler MS-6395, Honda HTO-06, and ILSAC GF-6A, making OE 5W-30 the everyday choice for owners who want a true synthetic motor oil at the OEM drain interval without paying for extended-drain coverage.
Advanced wear protection for modern engines
Smaller-displacement turbocharged and direct-injection engines apply more load to camshafts, lifters, and rings, and any cam wear that develops shows up as poor valve timing and lost efficiency. OE 5W-30 delivers 47 percent more wear protection than required by the GM dexos1 Gen 2 specification, based on independent testing of OE 0W-20 in the Peugeot TU3M Wear Test (CEC L-38-A-94), the 100-hour, four-cylinder wear protocol referenced by dexos1 Gen 2. That added margin protects pistons and cams in the high-stress environments where modern downsized engines spend most of their service life.
LSPI defense for turbocharged direct-injection engines
Low-speed pre-ignition (LSPI) is the spontaneous ignition of the fuel and air mixture before the spark fires, and it can break pistons and connecting rods in turbocharged gasoline direct-injection (GDI) engines. The OE additive system is engineered to suppress the chemistry that triggers an LSPI event. OE 5W-30 produced zero LSPI events across five consecutive runs of the LSPI engine test required by the GM dexos1 Gen 2 specification, delivering 100 percent protection against LSPI on the dexos1 Gen 2 protocol.
Cleaner engines and deposit control
The 100 percent synthetic base oils resist chemical breakdown that produces varnish, sludge, and ring-pack deposits, while the detergent and dispersant additive package suspends combustion contaminants until the next oil change. OE 5W-30 is friendly to modern emissions hardware, supporting proper operation of catalytic converters for full service life and low tailpipe emissions, and it carries the API "Resource Conserving" designation that signals fuel-economy performance on the API Sequence VIE/VIF fuel economy protocol.
All-temperature performance and viscosity stability
OE 5W-30 posts a CCS viscosity of 5,680 cP at -30 C in ASTM D5293, supporting fast oil flow to cams and bearings during a cold start, and a pour point of -48 C in ASTM D97 keeps the formula fluid in winter. At operating temperature, kinematic viscosity is 10.1 cSt at 100 C in ASTM D445 with a viscosity index of 159, and a NOACK volatility of 6.8 percent weight loss in ASTM D5800 limits oil consumption and deposit-forming evaporation. The 3.2 cP high-temperature high-shear viscosity at 150 C in ASTM D5481 keeps the oil film stable in turbocharger journal bearings and at the piston ring zone.
OEM specification coverage
The OEF 5W-30 viscosity is built for the spec list that most late-model North American gasoline owners' manuals require: API SP (Resource Conserving), API SN Plus, GM dexos1 Gen 3 (supersedes dexos1 Gen 2, LL-A-025, 6094M, and 4718M), Ford WSS-M2C946-B1, Chrysler MS-6395, Honda HTO-06, ACEA A1/B1 and A5/B5, and ILSAC GF-6A and GF-5. Owners who follow the manual rather than chase extended drains get the same dexos1 Gen 2 LSPI and wear test results in a 100 percent synthetic oil priced for routine service.
Recommended applications and service intervals
OE 5W-30 is intended for gasoline-fueled passenger cars, light trucks, SUVs, and crossovers that specifically call for an SAE 5W-30 viscosity and one of the service categories listed above. The drain interval is the one stated by the vehicle manufacturer or indicated by the oil life monitoring system, not an extended interval.
Normal service: follow the vehicle manufacturer's recommended drain interval or the oil life monitoring system, whichever the owner's manual specifies.
Severe service: follow the manufacturer's severe-service interval for towing, hauling, dusty environments, frequent short trips, or extended idling.
Modified engines, racing vehicles, and engines running alternative fuels such as E85, CNG, or propane should follow the engine builder's interval rather than the factory schedule.
Outside the United States and Canada, follow the vehicle manufacturer's recommended drain interval.
The oil filter should be changed at every oil change. OE 5W-30 is compatible with other synthetic and conventional motor oils, but mixing shortens oil life and reduces performance, and extended drain intervals are not supported when oils have been mixed. Aftermarket oil additives are not recommended for use with OE 5W-30.

Order OE 5W-30
OE 5W-30 100% Synthetic Motor Oil is available in a quart bottle (product code OEFQT-EA), a case of 12 quarts (OEFQT-CA), a gallon jug (OEF1G-EA), a 55 gallon drum (OEF55-EA), and a 275 gallon tote (OEF27-EA). Using AMSOIL synthetic lubricants does not void a new vehicle or equipment manufacturer warranty, and OE 5W-30 is backed by the AMSOIL Limited Warranty as a Warranty Secure replacement for vehicle manufacturer-branded oils. Confirm the right grade for the vehicle with the AMSOIL Vehicle Lookup Guide, compare 5W-30 options across product families in the 5W-30 Oil Guide, then order AMSOIL OE 5W-30 100% Synthetic Motor Oil.
Is AMSOIL OE 5W-30 a true full synthetic motor oil?
Yes. OE 5W-30 is a 100 percent synthetic gasoline engine oil. The formulation uses synthetic base oils that resist chemical breakdown, supporting cleaner pistons and steady viscosity through the full factory drain interval.
What is the difference between AMSOIL OE 5W-30 and Signature Series 5W-30?
OE 5W-30 is built for the drain interval stated by the vehicle manufacturer or shown by the oil life monitoring system. Signature Series 5W-30 carries a longer-drain additive system and supports drain intervals up to 25,000 miles in normal service. Owners who follow the owner's manual schedule generally choose OE 5W-30, while owners running extended drains generally choose Signature Series.
Which OEM specifications does OE 5W-30 meet?
OE 5W-30 meets API SP (Resource Conserving), API SN Plus, GM dexos1 Gen 3 (supersedes dexos1 Gen 2, LL-A-025, 6094M, and 4718M), Ford WSS-M2C946-B1, Chrysler MS-6395, Honda HTO-06, ACEA A1/B1 and A5/B5, and ILSAC GF-6A and GF-5. The owner's manual should list one of these service categories before the oil is used.
Will OE 5W-30 protect a turbocharged direct-injection engine against LSPI?
Yes. OE 5W-30 produced zero LSPI events across five consecutive runs of the LSPI engine test required by the GM dexos1 Gen 2 specification, delivering 100 percent protection against LSPI on that protocol. That coverage is targeted at turbocharged gasoline direct-injection engines where LSPI is most damaging.
How often should OE 5W-30 be changed?
Follow the drain interval stated by the vehicle manufacturer or indicated by the oil life monitoring system. Change the oil filter at every oil change. OE 5W-30 is not positioned as an extended-drain oil, so drain coverage beyond the manual schedule is not supported.
Can OE 5W-30 be substituted for a 5W-20 or 0W-20?
Substituting a 5W-30 in an engine that calls for 5W-20 or 0W-20 is not recommended. Late-model engines designed for thinner viscosities use tighter clearances and lower friction targets, so the correct grade is the one printed in the owner's manual. The AMSOIL Vehicle Lookup Guide confirms the right viscosity for the application.
Will using OE 5W-30 void a new vehicle warranty?
No. Using AMSOIL synthetic lubricants does not void a new vehicle or equipment manufacturer warranty, and OE 5W-30 is Warranty Secure as a replacement for vehicle manufacturer-branded products, backed by the AMSOIL Limited Warranty.
