Are you sure about that? My owners manual says:

(Sorry, don't know how to translate pingel. Knock, maybe?)
Don't know if the numbers in Europe mean the same as in the US. But the recommandation 'or higher' doesn't contain a warning.
Further off-topic: as far as I know here in the Netherlands only 95 and 98 is sold. I remember to have seen 92 somewhere next to a highway abroad. I wouldn't know where to buy 90.
So either the numbers mean something different, or petrol in the US is different from petrol here. 87?
