When shopping for a motor oil, it’s important to know whether a product is dependable enough to protect your vehicle. Primarily, this is done by checking an oil’s specification — the product’s test results of how it well it performs compared to the industry standard.

With today’s advanced engines becoming more rigorous on motor oils than ever before, this specification standard has undergone a major update to ensure that oils continue meeting demands to protect modern vehicles.

GF-6, as this new specification is known, was released in May 2020 by the International Lubricants Standardization Approval Committee (ILSAC). So, what’s new about GF-6 motor oils and what do these changes mean for you? Read on to find out.

Why the change? And what’s new?

ILSAC GF-6 is the sixth generation of specifications aiming to standardize lubricants to meet the demands of evolving engine technology. While today’s engines are better than ever, the tradeoff is that they also create higher demands on an oil’s performance.

So, how does ILSAC GF-6 ensure that motor oils are up to the task? The new specification provides a different chemistry within the engine oil that improves wear, oxidation and corrosion control. As a result, the oil provides better overall performance for the engine — with benefits like increased fuel economy, less engine wear and a longer engine life span.

GF-6A vs. GF-6B

With this update, two different classifications exist under the ILSAC GF-6 spec: GF-6A and GF-6B.

ILSAC GF-6A oils are backward-compatible, meaning they can be used on all engines designed for previous ILSAC specifications. Although older engines may not require the new and improved oil that ILSAC GF-6A offers, they will likely still see performance benefits.

Meanwhile, ILSAC GF-6B oils are recommended for only select new-model vehicles. Available only in SAE 0W-16 viscosity grade, GF-6B oils have a lighter viscosity and run thinner compared to GF-6A oils. Importantly, ILSAC GF-6B oils are not backward compatible. As always, be sure to check your vehicle’s owner’s manual to determine which product to use.

What does it mean for you?

It’s always important to know what you’re putting in your vehicle, especially when it comes to your motor oil. Cenex® has already adjusted its GASOLINE ENGINE OILS to meet the new ILSAC GF-6A specification.

When bringing your car to an oil change service or certified mechanic, you won’t see any change. Licensed professionals will be aware of the update and have the proper oil for your vehicle. If you perform your own oil changes, be sure to check your vehicle’s owner’s manual to determine which engine oil is best for your engine. If you find yourself needing to top off your engine oil, new ILSAC GF-6A oil can be mixed with existing GF-5 oil without issue.
