Should you change multi-grade oils before seasonal changes?

Keeping your engine oil fresh and clean is a good way to help your motor endure for the long haul. That said, using oil with the wrong viscosity rating for your motor can have a detrimental effect on matters.

Your oil viscosity describes how it responds to varying engine temperatures and pressures. The conditions inside your engine vary from mild to severe, and the oil must be hardy enough to perform under all of them. The viscosity rating numbers give you a quick way to size up potential multi-grade oil candidates for your unique motor.

Multi-grade oils maintain their structural integrity at various temperature levels. To get the most out of them, you need to make sure you select the correct grades for your vehicle and driving needs.

Multi-grade viscosity codes include several numbers and letters. The numbers refer to the viscosity levels and the number "W" to cold-weather compatibility. Examples are:

  • 0W-20
  • 5W-20
  • 10W-30
  • 15W-30

Inspecting your oil system for possible issues is a good idea before cold weather arrives, and here at our Audi Allentown service center, our oil system technicians are ready to put their years of experience at your disposal. Swing by today for a no-obligation consultation.
