How to decide

The manufacturer oil specification and certification control the choice. A synthetic label alone does not prove the oil meets a required OEM approval.

Check grade, manufacturer standard and current product approval, then use the manual’s service rule. Longer marketing life claims do not extend a vehicle-specific interval.

Neither option should be labeled universally better without a specific product, test and vehicle application. We have not tested these products.

Review sourced OEM part numbers and choose your vehicle before ordering.
