According to the Acura MDX owner's manual, "Your vehicle is designed to operate on unleaded gasoline with a minimum octane rating of 87." However, the manual also notes that "using premium unleaded gasoline with an octane rating of 91 or higher may provide some performance benefits."
The decision of whether or not to use premium unleaded gasoline in your Acura MDX is up to you. If you are looking for the best possible performance, then you may want to consider using premium unleaded gasoline. However, if you are looking to save money, then you can safely use regular unleaded gasoline.
