I would THINK Sta-Bil, but would check with your dealership for their recommendations.

That’s a great question Anthony, and one I didn’t know the answer to until recently. A prior post here by Sisyphus1 asked a similar question on that subject.

@GorehamJ: very good article. Learned something new today! But it illustrates how complicated a modern gas engine is.
