18 MPG combined is what you’ll likely get with a 2018 Nissan Titan 4WD model that has the 5.6L V8 engine. This fuel economy won’t convert midsize truck or crossover drivers, but it’s the trade-off for the Titan’s strong capability, ruggedness, and no-frills design. These trucks are bought by people who want a real workhorse more than top fuel efficiency, and they know that going in.

City and highway performance

Looking at the separate fuel economy figures, the 2018 Titan 4WD 5.6L V8 gets 15 MPG in city driving. Stop-and-go traffic and the large engine size hurt efficiency. On the highway, expect around 21 MPG. While 21 MPG isn’t the best in its class, it’s good enough for longer trips where a steady speed lets the engine work better.

Annual fuel cost

The EPA says the annual fuel cost for the 2018 Nissan Titan 4WD 5.6L V8 is $2,450. This is based on driving 15,000 miles a year using the national average gas price. Your actual costs will change based on how much you drive and gas prices where you live. If you drive way more than 15,000 miles a year, especially if you often tow or haul heavy stuff, plan to spend a lot more on fuel each year.

Real-world expectations

EPA estimates are a good starting point, but real-world fuel economy is often different. Factors like how you drive, the terrain, weather, and how well you maintain your truck all matter. If you speed up fast, brake hard a lot, and don’t keep up with maintenance (like tire inflation and air filter replacement), your fuel use will go up. Owners who mostly use their Titan for short trips or in heavy traffic probably won’t get the EPA’s combined figure. On the other hand, if you drive smoothly and keep a steady speed on the highway, you might see slightly better numbers. Also, adding aftermarket parts, like oversized tires or heavy-duty bumpers, can lower fuel economy.

How it compares

The 2018 Titan’s fuel economy is pretty competitive for a full-size, four-wheel-drive truck, but there are differences. The 2018 Ford F-150 with the 2.7L EcoBoost V6 gets better fuel economy at 20 MPG combined. Some buyers prefer the normal feel of the Titan’s naturally aspirated V8. The Chevrolet Silverado 1500 with the 5.3L V8 and four-wheel-drive gets 17 MPG combined, which is a bit less than the Titan. Ram 1500 trucks from the same year get similar numbers. All all Nissan fuel economy data shows that better efficiency standards are increasingly prioritizing economy while maintaining utility. Choosing a truck means balancing fuel economy with things like towing, payload, and the truck’s other features.

Tips to maximize efficiency

Since the Titan has a V8 engine and is meant to be a work truck, here are some things owners can do to get better fuel economy. Don’t speed up too fast and try to keep a steady speed when you can. The Titan’s V8 has lots of torque, so you don’t need to floor it to get up to speed. Gently pressing the gas pedal will help save fuel.

Check your tire pressure often and keep it right. Tires that don’t have enough air increase rolling resistance, making the engine work harder and burn more fuel. Look at the sticker on the driver’s side door for the right tire pressure numbers. A simple tire pressure gauge is a cheap tool that can make a difference.

Don’t let the engine idle. Leaving the engine running for a long time, whether to warm it up in the winter or when waiting, wastes fuel. If you’re going to be stopped for more than a minute, it’s usually better to turn off the engine and start it again when you’re ready. This is especially true with the Titan’s big V8 engine.

Drive lighter. Carrying extra weight puts more stress on the engine, which lowers fuel economy. Take out anything you don’t need from the truck bed or inside the cab. Even a few hundred pounds of extra weight can matter, especially when driving in the city.

Think about using cruise control on the highway. Cruise control helps keep a steady speed, which can improve fuel economy on long trips. Avoiding sudden speed changes and keeping a consistent pace helps fuel efficiency when driving on the highway. Cruise control works best on roads that are pretty flat, so turn it off when going up steep hills.
