I will admit I run Premium in my cars. 2 reasons: 1-I have advanced my timing as much as the distributor slots will allow, 2-In the event of an overheat situation or a slightly lean burn situation (such as a momentary fuel starve) there is a less likely chance of lean detonation which could be catasrauphic. It may be overprcautionary and may not even work but for the few extra cents it costs it is worth the possible peace of mind.
