I recommend changing your oil as soon as you get the car with basic 5w30 oil. Then @ 1200 miles use the nissan ester oil. @ 5000 miles switch again to a premium synthetic. Redline, Royal purple & amsoil. Engine will run supersmooth with 23mpg avg. see full Nissan Z review

It was worse than my 303 hp 5.3L V8 Grand Prix, and though it was faster off the line (by about .3 seconds), the Grand Prix GXP was much faster in highway gears. So better MPG and more juice at highway speeds made the GP a better choice for me. see full Nissan Z review

This car's fuel economy shows how much the world has moved forward with regards to fuel management. My commute is pretty much 50/50 city/highway, and I get 19-22 MPG on average depending on weather and A/C usage. My best tanks were in the 26-27 MPG range on those long trips to NY/FL. For reference, a 335i makes more power and probably averages about 22-24 MPG in mixed driving and can get over 30 MPG no problem on the highway. When you drive ~25000 miles a year that definitely adds up. see full Nissan Z review

Fuel economy is abysmal around town. I guess that's the price you pay for going grocery shopping with over 300 HP. However, on the highway it's very possible to exceed the EPA mileage number. see full Infiniti M review
