Premium Unleaded fuel only

Asked by Deniece Saunders

There is a sticker near the fuel filler that I should use Premium Unleaded fuel only in my 2004 Nissan Maxima STL V6 sedan. As this petrol is quite a lot dearer can you tell me if it is necessary to use premium petrol all, some, or none of the time?

The engine is tuned to run at its peak on Premium Unleaded fuel, which has an octane rating of 95. By using that fuel you will get better performance and better fuel economy, most likely better fuel economy than you would when running on the cheaper Regular unleaded. Nissan approve the use of E10 ethanol blend fuel, so that would be the best alternative fuel if you can't afford Premium.
