FAQ:

Q: What is the difference between GF-2 and GF-3 motor oils?

A: The GF-2 standards requires 0W-30, 0W-40, 5W-20, 5W-30, 5W-40, 5W-50, 10W-30, 10W-40 and 10W-50 motor oils to meet stringent requirements for phosphorus content, low temperature operation, high temperature deposits and foam control. An ILSAC GF-3 an oil must meet both API SL and the EC-II requirements.

Q: What is ILSAC GF-4 oil?

A: ILSAC GF-4 was first introduced in 2004 for use in gasoline engines in passenger cars. API has discontinued licensing engine oils against ILSAC GF-4 and it became an obsolete specification in September 2011.

Q: What is the GF-3 standard?

A: The GF-3 standard has more stringent parameters regarding long-term effects of the oil on the vehicle emission system, improved fuel economy and improved volatility, deposit control and viscosity performance. The standard also requires less additive degradation and reduced oil consumption rates over the service life of the oil.

Q: What is the difference between ILSAC GF-5 and GF-6?

A: The ILSAC GF-6 specification is currently in development and will probably be divided into two sub-specifications. ILSAC GF-6A will be fully backward compatible with ILSAC GF-5 but would offer better fuel economy, better engine protection and improved performance while maintaining durability.
