Anyway, the answer is yes.
The GEs and most other cars WILL run on gasoline with octane higher than the ones REQUIRED.
Some people CLAIM a performance boost (responsiveness, etc). Others CLAIM better fuel efficiency and more KM per peso spent, but a lot of that will be difficult to prove due to varying traffic conditions and driving styles.
Some also say that gas manufacturers add some additives to their premium fuel mixes to make the gas burn 'cleaner', making it good for the engine.
^This I cannot prove/disprove.
With regards to any long term damage however, there's nothing wrong with using higher octane gasoline as compared to using the minimum octane gasoline. Well again, I'll assume that this is the answer because proving it is really difficult (varying conditions car is exposed to).
In the end, I'd say whichever floats your boat. Basta your engine doesn't knock from using octane LOWER than what is required.
Do take note that when the manual says 88 octane, you'll need 90++ octane here in the philippines because of the way octane ratings are given here and abroad.
Hope this helps and clears up a few things.
