Doing some maintenance work on my new Mustang. Factory calls for 5w20 motor oil. Talked to Royal Purple today and they suggested their 5w30 XPR oil since I'm running a supercharger at fairly high boost levels.

What are you guys running?

I'd run the royal purple 5w30. The 5w20 really just saves gas mileage.

Still NA and run 5W30 Mobil 1.

Here in Florida I run 10W-30 synthetic, 5W-20 is too thin for the ambient temps here...
