Mazda RX-8 Real Gas Mileage: Cons
YearBody/PowertrainComment
2009 4dr Coupe 232-horsepower 1.3L R2
6-speed manual RWD
One of the big downsides of the rotary is truly horrendous fuel economy. When the RX-8 first came out in the early 2000s, its mileage ratings of 16/22 city/highway mpg (stick shift) were just barely acceptable, but there days, with many crossovers hitting more than 30 mpg on the highway, those figures are truly atrocious, especially given respectable but certainly not neck-snapping power. Futhermore, it takes premium. If you're using the RX-8 as it commuter, fuel costs will add up quickly. In my predominantly around-town driving, I typically average between 16-17 mpg. My highest recorded average was 20 mpg on a highway trip at speeds around 75 mph. see full Mazda RX-8 review

The EPA numbers are way low compared with my real-world experience. The window sticker showed 18/25 and I have never seen less than 23 with my 40/60 city/highway commute. I think Mazda should develop a lean-burn economy cruise mode for this car. see full Mazda RX-8 review

Not that bad for what it is, but it seems to me that Mazda's Sky Active technology could help the city mileage. It just needs more R&D. see full Mazda RX-8 review

For a small engine displacement and a relatively light vehicle weight, the gas mileage is weak. I usualy get around 19mpg, and that does not realy matter if I am doing all city or all highway driving. I think the real problem is in the sixth gear it isnt much different than fifth gear so it does not provide good fuel economy. see full Mazda RX-8 review

For a car with a 1.9 liter engine I would have expected better than 16-19 MPG. Get your foot into it and the numbers fall drastically. Otherwise I loved that car. It just got too small with a newborn and a big dog. see full Mazda RX-8 review

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
