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

Very Good and exactly as projected with pump fuel 93. Higher octane race fuel affords better mileage ,as with any vehicle proper maintenence ensuring air filters are clean . I change my oil every 3-5 000 miles and I love this car 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

You have to drive like a grandma to get the estimated gas mileages. more realistically you are looking at 15-19mpg average, totally dependant upon how you drive. see full Nissan Z review

TrueDelta Reviews the Real Gas Mileage of the Buick Regal

Buick Regal Real Gas Mileage: Cons
YearComment
2011 The Buick Regal and Chrysler 200 both weigh substantially more than just about any other front-wheel-drive midsize sedan. Add all-wheel-drive, and both weigh nearly two tons. Curb weight is the enemy of fuel economy. The Buick's turbocharged four-cylinder engine is more efficient than the Chrysler's V6, so it has an edge in the EPA's city test, 19 vs. 18 mpg. But the Chrysler's automatic transmission has three extra gears, for a total of nine, so it has the edge on the EPA's highway test, 29 vs. 27 mpg. The Ford Fusion, though far from light, has an edge over both: 22 mpg city, 31 mpg highway. see full Buick Regal review

For being a turbo 4, I expected slightly better MPG (I average 26mpg mixed with premium). When adding in the Trifecta Performance tune on the car, I average around 29mpg, with the added HP/TQ. What gives, GM? Uncage this beast! see full Buick Regal review
