Much of the recent passenger car lubricant news has been focused on the proposed API SN-Plus supplemental category. North American and Asian automakers though have made it clear that their main goal is still to get the ILSAC GF-6 engine oil category upgrade in place as soon as possible, with no delay due to the introduction of the supplemental category.
API SN-Plus (a stop-gap designation to address engine-impairing low speed pre-ignition) became needed because of ongoing delays in developing GF-6s engine tests. For some time now the Auto-Oil Advisory Panel responsible for creating GF-6 has not wanted to issue a revised official time line for its launch; theyre waiting until all the required new tests are in place and theres much less probability that the timing will change again. The American Petroleum Institute then can set a date for when compliant products may show the new category on their labels.
