10W-30 Synthetic Oil (OET)

Amsoil OE 10W-30 Synthetic Motor Oil is specially formulated for the longer oil change intervals recommended by vehicle manufacturers today. Its advanced synthetic technology resists chemical breakdown for maximum wear protection (and peace of mind) well beyond the traditional 3,000-mile oil change interval.

AMSOIL OE 10W-30 (OET) Synthetic Motor Oil helps provide better wear control, improved high- and low-temperature protection and increased fuel economy compared to conventional oils. The oil drain interval recommendations for many of today's vehicles extend well beyond the traditional 3,000-mile interval, especially when electronic oil monitoring systems are used. AMSOIL OE Oil provides excellent protection and performance for the entire length of the original equipment manufacturer's recommended drain interval.

AMSOIL, the leader in automotive synthetic lubrication, produced the world's first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your engine.

Protects Pistons from Low-Speed Pre-Ignition

OE Synthetic Motor Oil features unique chemistry proven to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. A properly formulated motor oil is critical for protecting your engine against LSPI.

Peugeot TU3M Wear Test

Original equipment manufacturers (OEMs) like GM have addressed the issue by designing tests to determine a motor oil's ability to prevent LSPI. OE Synthetic Motor Oil achieved 100 percent protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification– zero occurrences were recorded throughout five consecutive tests.

Better Gas Mileage

Formulated with friction modifiers, AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is a fuel-efficient oil that reduces friction-related energy loss. It provides better fuel economy compared to conventional, non-fuel-efficient motor oils.

Lowers Maintenance Costs

AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is friendly toward modern emissions-control systems, promoting proper operation of catalytic converters for optimum service life and low exhaust emissions.

Protects Against Extreme Temperatures

AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is a multi-viscosity formulation. It resists the effects of thermal breakdown, including evaporation and viscosity loss, while remaining fluid in cold temperatures for easier cold starts and fast startup circulation.

Engines Stay Clean

Fortified with high levels of detergent and dispersant additives, AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is engineered to resist sludge and carbon deposits better than conventional oils. It promotes clean operation for longer-lasting, better-running engines.

Bid Appropriate

AMSOIL OE 10W-30 (OET) Synthetic Motor Oil fulfills the requirements of most public and private purchasing bids. It is cost-effective, making it ideal where synthetic motor oil is specified.


AMSOIL OE 10W-30 (OET) 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:

10W-30 (OET)

  • API SN PLUS (Resource Conserving), SM…
  • ACEA A1/B1, A5/B5
  • GM 6094M, 4718M
  • Chrysler MS-6395
  • Ford WSS-M2C205-A
  • ILSAC GF-5, GF-4…


AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing AMSOIL OE 10W-30 (OET) Synthetic Motor Oil with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. Aftermarket oil additives are not recommended for use with AMSOIL OE 10W-30 (OET) Synthetic Motor Oil.

Service Life

In gasoline-fueled vehicles, AMSOIL OE 10W-30 (OET) Synthetic Motor Oil is recommended for the intervals stated by the vehicle manufacturer or indicated by the oil life monitoring system. Change oil filter at every oil change.
