:confused: I recently bought a 05 Nissan Maxima. I tell me to put in premium fuel to get maximum performance. With gas prices so high am I able to put in anything less that premium? Will I reck my engine? Will there be a residue deposit in the engine? Or will the car just not go as fast? Thanks

Using 87 octane in most cars will give you all the performance you need.
Certain cars however can require only 93 octane check to see if yours is one of them. It
Will likely state this near filler neck like on the gas cap door or by your fuel gauge on dash.
