proper fuel to be used in vehicle

It calls for high octane in my Acura, I use mid grade for 100K and see no difference but I would ask the dealer what consequences they have seen from any of there customers. Post the question on Acurazine its a great Acura forum.

absolutly not your car and engine was designed for maxium power and fuel econemy and engine life dont cheap out use prem fuel only . your car has a engine computer that knows as soon as you put in reg fuel by the knock sensor and it will retard the timing hence less power and less fuel econemy ( 30 year honda tech )
