The prevailing wisdom is using higher octane than required by the manufacturer is a waste of money. An exception might be with a tuner installed, but not having a tuner I do not know. I understand that using higher octane than required, while a waste of money, would not hurt anything, but I seem to recall reading on this forum under one of the many octane threads, using higher octane can have an ill effect. As mentioned our trucks manual recommend 89 but indicate 87 is ok to use. I have always run the highest octane required or suggested by the manufacturer, so I have run nothing but 89 in my truck.
