I have been straight regular fuel since 2008 when the economy crashed. I didn't have the extra $.50/gallon so I ran regular and let the knock sensors do their work and adjust the timing map compensations. I never went back to premium but I never really drive aggressively.
Both cars have been no problem now for 13 years, even the Dinan E46 tune.
