Having problems with your 2005 Nissan 350Z ?

Im curious about octane in fuel and what it does. I have a Nissan 350Z that requires 91 octane. Now if I were to put 94 or higher, would it improve performance or fuel efficiency at all or is it just a waste of money to put more octane then the recommended amount? Thanks

Answers :

Octane is an added ingredient that burns more efficently than gasoline..use the 91 octane rating that your owner's manual specifies. Lower octane will degrade performance, higher than 91 is wasting money because it has more octane and is more expensive, but does not improve performance.
