Demanding driving

In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended periods at higher altitudes than normal, it may be advisable to switch to higher octane fuel (91 or higher) or to change gasoline brands to fully utilize your engine's capacity, and for the smoothest possible operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be necessary
to fill the tank more than once before a
difference in engine operation is noticeable.
