Royal Purple suggests adhering to manufacturer’s recommended oil change intervals for vehicles under warranty using Royal Purple API-licensed SAE motor oils. With Royal Purple HMX® and HPS series oils, drain intervals may be extended to 15,000 miles (20,000 km) or one year, whichever occurs first in street-driven, mechanically-sound vehicles. For guidelines specific to your vehicle, we recommend contacting our technical department 888-382-6300.

Once manufacturer warranty is no longer a concern, with the Royal Purple API-licensed SAE motor oils drain intervals may be extended up to 12,000 miles (19,200 km) or one year, whichever occurs first in street driven, mechanically-sound vehicles.
