Averaging 22mpg for th full 57,000 miles I have driven. Winter mileage is less and summer is more Using winter snow and ice tires in winter months. Hwy tires in summer months. see full Nissan Frontier review
2008 4dr Extended Cab 6ft bed 154-horsepower 2.5L I4
5-speed manual RWD
The best so far has been 27 mpg. The worst 19mpg. Average for over 6,000 miles of mostly highway driving has been 23 mpg. At 17,800 miles on odometer the milage is down to 22 mpg. I added 4 new snow tires that have reduced mpg. see full Nissan Frontier review
Nissan Frontier Real Gas Mileage: Cons
YearBody/PowertrainComment
2013 4dr Crew Cab 5ft bed 261-horsepower 4.0L V6
5-speed automatic RWD
I keep a detailed log of fuel economy. I commute on hour each way, every day. 50% of the time is spent at 65 mph on the highway, and the remainder between 50 and 60 on 2-lane country roads. Only a few stops in between. Very consistently getting 21.5 to 22.3 mpg. I rarely rev it above 4000 RPM - only when passing someone. That happens maybe once or twice per tank. I am underwhelmed by the fuel economy. Full-sized trucks with larger, stronger V8s get similar economy. see full Nissan Frontier review

This 2011 Frontier Crew Cab at 4,000 miles is averaging 19-21 hwy, 16-19 city depending on weather and traffic conditions. see full Nissan Frontier review

Well it has a 4.0L V6, so I guess I should have expected it. It does have nice power though. see full Nissan Frontier review

Well, the EPA ratings are 15 city 20 Highway. The salesman I dealt with says it is easy to get 20 Highway, and I am not an aggressive driver. The V6 is geared low enough that it does 1800 rpm at 60MPH, so my light foot will help here. We will see ! see full Nissan Frontier review

Even though it is a powerful V6, economy was on par with much more powerful V8 engines. see full Nissan Frontier review

I cant complain about the gas mileage it was around 22mpg when new but with a lift and tires I have sucked some of that away see full Nissan Frontier review

Overrated to what is identified. I know it is a truck but the mileage is far from what Nissan claims. see full Nissan Frontier review
2004 2dr Extended Cab 6ft bed 180-horsepower 3.3L V6
5-speed manual 4WD, part-time w/low range
Average 17/21 during the summer. A friends 96 F-150 (also 4x4) gets 16/20 with a V-8. Expected much better mileage from a small truck. see full Nissan Frontier review
 

TrueDelta Reviews the Real Gas Mileage of the Mazda MX-5 Miata

Mazda MX-5 Miata Real Gas Mileage: Pros
YearComment
2016 Nothing has improved more with the Mazda MX-5 Miata's latest redesign than its fuel economy. The 2015 managed only 21 mpg city and 28 mpg highway in the EPA's tests, disappointing for such a light car powered by a naturally aspirated 2.0-liter engine. The new car tests much better: 27/34 with a manual transmission and 27/36 with an automatic. The MINI Cooper S Roadster was about equally efficient when equipped with a manual transmission (26/35), a little short with an automatic (25/34). The new MINI Convertible, if it shares the Hardtop's EPA ratings, won't be as efficient with a manual transmission (23/33) but will be as competitive as its predecessor with an automatic (26/33). The Scion FR-S barely out-economizes the old Miata with a manual (22/30) but is just a couple mpg short of the new one with an automatic (25/34). Premium fuel is recommended in all of these cars. The new Miata can use regular unleaded at the cost of some responsiveness. In my real-world driving of the new Miata with an automatic transmission the trip computer reported a suburban average around 30 mpg. On a 60-mph highway the average can reach 40, about 4 mpg better than a Scion FR-S and 5 mpg better than a MINI JCW Clubman, both tested with manual transmissions. Drive at 75 mph with the top down, though, and the reported average will fall to 34 mpg. The largest fuel economy advantage over the Scion FR-S appeared when both were flogged along Ohio's Route 26. The Scion's fuel economy dipped into the high teens, but the Mazda's only into the mid-20s. The most likely reason: the torquier, far less peaky Mazda engine doesn't have to be revved nearly as high to reach its sweet spot. The JCW Clubman, its turbo reducing the need for fuel-guzzling runs to the red line, fell between the two with a "spirited driving" average around 20 mpg. Overall, with the redesign the Miata's fuel economy has gone from worst to first. see full Mazda MX-5 Miata review
Mazda MX-5 Miata Real Gas Mileage: Cons
YearComment
The first four "why nots" shouldn't have come as a surprise to anyone. This one might. I didn't ding the MX-5 Miata's engine for its power output, but I am going to ding it for its fuel input. While EPA ratings of 21 mpg city and 28 mpg are hardly abysmal, the FR-S does better (22/30) and a 315-horsepower Porsche Boxster S does about as well (20/28). With one of Mazda's new SKYACTIV engines, the Miata would go much farther on a gallon of gas. (The 2,900-pound Mazda3 is rated 27/39.) But this engine won't happen until the Miata is again redesigned. see full Mazda MX-5 Miata review

Excellent mileage. I get 36mpg on normal highway cruises and about 28mpg in town. When I go to the race track, I run around 22-24 mpg. If you are really savvy, this car burns about 2 gallons an hour! So cheap to keep on the road. see full Mazda MX-5 Miata review
