Castrol GF-6 Update - Part 1

Development of ILSAC GF-6, the new passenger car oil specification, is continuing to take shape. First allowable use of the GF-6 specification is targeted for December 2017. This date is dependent on a number of factors, but the two key factors are the completion of the new Heavy Duty oil specification (PC-11) and the development and completion of new tests for the GF-6 spec.

Many GF-6 engine tests require new tests to be developed because the current tests are out of date with today’s engines and test parts are running out. Tests are being developed for the oxidation, wear, sludge and fuel economy tests.  In addition, new tests are being developed to measure the performance of how an oil protects turbochargers, reduces or prevents chain wear and minimizes low-speed pre-ignition (LSPI). The independent test labs have been working with the engine manufacturers to develop tests for the new GF-6 specification.

New GF-6 tests are required because new engine designs are pushing more power out of smaller engines. Engine technologies such as gasoline direct injection (GDI) and turbochargers are boosting engine performance, engine efficiency and fuel economy. But the gain in power and efficiency in these engines can present new challenges for the lubricant in controlling deposits and wear. The new GF-6 category will better align with the needs of these engines to improve overall protection.

The development of ILSAC GF-6 is moving along well, but there is still much work to be completed before the specification is complete. The Castrol Technical team is working with the industry and our suppliers to make sure that we stay up to date and have our products ready to upgrade to the new specification once it is available.
