Yep, use the premium, they are prone to head gasket failures to begin with, so don't chance it!

You must put in premium fuel. Realize that midgrade fuel is regular and premium fuel mixed together. Petrol stations do that to sell more premium.

The knock sensor should catch it - try midgrade - if it knocks under heavy acceleration go back to premium or stop heavy acceleration
