Chevron has you covered on GF-6 motor oils


As auto manufacturers continue the drive toward efficiency and fuel economy, demands on powertrains and their components are increasing. Today’s engines must be smaller, lighter, and more efficient, all without sacrificing performance or power. The performance demanded of these engines, and the technology required to achieve it, result in an increasingly severe operating environment. Motor oil technology must also meet the demands of these modern engines. 


That is the reason for the new International Lubricant Specification Advisory Committee (ILSAC) GF-6 standard, and yes, Chevron will introduce new passenger car motor oils that meet this standard, helping make new, cleaner, more efficient engine technologies possible.

GF-6 is the new industry standard for ILSAC grade passenger car motor oils.  GF-6 motor oils will facilitate greater fuel economy while improving wear and deposit control, compared to their GF-5 counterparts. These new motor oils will protect against timing chain wear and Low Speed Pre-Ignition (LSPI), a potentially catastrophic phenomena that occurs in GDI (gasoline direct injection) engines.  Furthermore, consumers will benefit from new Chevron Havoline and Supreme GF-6 and API SP oils in the areas of fuel economy retention, wear, and LSPI protection, with unprecedented sludge and deposit control. 

When new GF-6 motor oils are introduced in 2020, they will be available in two sub-categories
for different generations of engine technology.


GF-6A in the applicable ILSAC viscosities grades (SAE 0W-20, 5W-20, 0W-30, 5W-30,
10W-30) will be backward compatible and carry the API “Starburst” Certification Mark.


GF-6B will only be for SAE 0W-16 and will not be backward compatible, for good reason: most existing engines were not engineered to run on such a low viscosity grade oil. Consequently, GF-6B qualified oils will wear a brand-new Certification Mark on their front label to differentiate them from GF-6A motor oils.

LSPI refers to an abnormal, premature engine combustion event at low speeds in which the fuel-air mixture ignites before intended, causing excessive pressures inside the engine’s cylinders. The higher power density of turbocharged, GDI (gasoline direct injection) engines makes them vulnerable to LSPI.  In mild cases, LSPI causes “super knocking” noises, but in more severe cases it can cause engine damage.  In response, the American Petroleum Institute (API) introduced a new specification, API SN Plus, a supplemental service category to address LSPI - while GF-6 test standards were in development.

SP is the next generation API service category and is applicable across viscosity grades.  API SP replaces API SN/SN PLUS and is backward compatible to all previous “S” service category oils. API SP and GF-6 share the same engine tests and performance limits; however, API SP maintains its own chemical and physical requirements.

The date of first license is May 1, 2020 and industry-wide implementation will take place over the following 12 months. 

As with any motor oil, Chevron recommends that you always refer to your vehicle’s owner’s manual.
