Use a 5W-30 from any of the premium brands.

Factory vs. Aftermarket: which oil is better?

Answered by Graham Smith · 20 Oct 2017

I would use the factory recommended oil, at least while the car is under warranty. Once the warranty has expired you could use the Mobil oil and shouldn’t experience any problems.
