Is HMX® different from your API-licensed engine oils?August 17, 2018
While no special oil filter is required, we do recommend upgrading to a high quality oil filter. A high quality filter will prevent contaminants from circulating through the system and causing damage.
For best performance and filtration, we recommend Royal Purple Extended Life Oil Filters. See our oil filter information page for more details or visit our dealer locator to find the dealer nearest you that carries our new filters.
