Any brand that meets the minimum service requirements the manufacturer calls for. Don't get caught up in marketing hype about how, for example, "Pennsylvania grade" oil is better. All top brands are basically the same. Check your manual, and look for the label on the bottle that specifies the service requirements the oil meets. All good name brands will likely meet whatever the current highest requirements are.
