Does it mean I can use #87 or #89 at the pump without any potential harm to the car except  a possible poor performance? I know there is a difference between PREMIUM FEUL RECOMMENDED and PREMIUM FUEL REQUIRED. I have both but using premium for both.  What's you guys' opinion on this?  Thanks for any input to the discussion.
