30 MPG combined isn’t going to set any records, but it makes the 2018 Nissan Altima SR 2.5L a pragmatic choice for those seeking affordable, reliable transportation with a dash of sporty flair. This isn’t a hypermiling hybrid or a groundbreaking EV, it’s a mid-size sedan aimed squarely at value-conscious buyers who prioritize dependability and a reasonably engaging driving experience over ultimate fuel efficiency.

City and highway performance

The EPA estimates of 26 MPG in the city and 37 MPG on the highway reflect the realities of the Altima’s powertrain. In urban settings, the 2.5L four-cylinder engine and continuously variable transmission (CVT) work diligently to balance acceleration with fuel conservation. The city MPG demonstrates that the Altima SR won’t bleed your wallet dry during stop-and-go commutes. The highway figure of 37 MPG is where the Altima shines, presenting an appealing option for long-distance drivers who appreciate a comfortable ride and predictable fuel costs, as well as buyers prioritizing ALTIMA MPG across all years.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2018 Nissan Altima SR 2.5L will be around $1,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. The Altima stands out because it offers impressive range; you will find yourself at the pump less than other vehicles in its class.

Real-world expectations

While EPA estimates provide a useful baseline, real-world fuel economy can vary based on driving habits, terrain, and vehicle maintenance. Aggressive acceleration, frequent hard braking, and neglecting routine maintenance can all negatively impact your MPG. Owners who prioritize smooth acceleration, anticipate traffic flow, and adhere to recommended service schedules are more likely to achieve or even exceed the EPA’s stated figures. The Altima isn’t particularly sensitive to driving style, but consistent habits pay dividends.

How it compares

Compared to its competitors, the 2018 Altima SR’s fuel economy holds its own. The Honda Accord LX with its 1.5T engine achieves an EPA-rated 33 MPG combined, giving it a slight advantage. The Toyota Camry LE boasts a combined rating of 32 MPG. A Mazda 6 with the base 2.5L engine achieves around 29 MPG combined, potentially making the Altima a bit more wallet-friendly. The Hyundai Sonata SE mirrors the Altima’s combined figure. The difference is very small, so drivers choose based more on what suits their needs from the interior to the driving experience.

Tips to maximize efficiency

One of the simplest ways to improve your Altima SR’s fuel economy is to ensure your tires are properly inflated. Check your tire pressure regularly and maintain the recommended PSI as indicated on the sticker located on the driver’s side doorjamb. Underinflated tires create more rolling resistance, reducing your MPG.

Avoid unnecessary idling. If you’re stopped for more than a minute or two, turn off the engine. Modern engines are designed to restart quickly and efficiently, so idling is just wasting fuel. This is especially true for the Altima, which lacks advanced stop-start technology.

Drive smoothly and avoid aggressive acceleration and braking. Gradual acceleration and gentle braking not only improve fuel economy but also reduce wear and tear on your vehicle. Use the Altima’s cruise control on the highway to maintain a consistent speed and minimize fluctuations in fuel consumption.

Keep your Altima properly maintained. Regular oil changes, air filter replacements, and spark plug maintenance are essential for optimal engine performance and fuel efficiency. A well-maintained engine runs more efficiently and burns fuel more cleanly. Review all Nissan fuel economy data for helpful details.

Lighten your load. Remove any unnecessary items from your trunk or backseat. Extra weight increases fuel consumption. Carrying around items you don’t need is like driving with an invisible passenger who’s constantly tapping the fuel pedal.
