21 MPG combined won’t lead the pack in fuel efficiency. But for the 2018 Toyota Tacoma 2WD with the 2.7L four-cylinder, it’s an acceptable trade-off for the capability and reputation this truck offers. This isn’t a vehicle bought by those prioritizing gas mileage above all else. It’s for contractors, small business owners, and weekend warriors who need a dependable, no-frills truck and are willing to accept middling fuel economy in return.

City and highway performance

The EPA estimates peg city driving at 20 MPG and highway driving at 23 MPG. These figures reflect the realities of a naturally aspirated four-cylinder engine working to move a truck designed for hauling. The city rating acknowledges the stop-and-go nature of urban environments, where the Tacoma’s engine needs to work harder to get up to speed. The highway rating, while slightly better, still reflects the aerodynamic limitations of a pickup truck. Those 23 MPG are achievable but will depend heavily on driving habits and load. Expect lower figures when carrying heavy payloads or towing a trailer.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Toyota Tacoma 2WD 2.7L 4-cyl at $2,100. This figure is based on driving 15,000 miles per year and using national average fuel prices. While individual expenses may vary based on local gas prices and driving habits, this $2,100 provides a benchmark for prospective owners. If you drive significantly more than 15,000 miles annually or consistently pay higher prices at the pump, expect your fuel expenses to exceed this estimate. If this concerns you, consider looking at all Toyota fuel economy data.

Real-world expectations

Official EPA numbers are a good starting point, but real-world MPG often varies. Expect to see numbers slightly lower or, in some cases, slightly higher than the EPA estimates. Factors influencing fuel economy include driving style (aggressive acceleration and braking will decrease MPG), tire pressure (underinflated tires create drag), and vehicle maintenance (poorly maintained engines are less efficient). The 2.7L engine, while reliable, is not overly advanced. It needs to be worked to get the Tacoma moving, especially with a load. This effort translates directly to fuel consumption.

How it compares

Compared to other mid-size trucks of the same era, the 2018 Toyota Tacoma 2WD 2.7L’s fuel economy is fairly typical. The Chevrolet Colorado with its base 2.5L four-cylinder achieved almost identical EPA ratings, 20 MPG city and 26 MPG highway. The Nissan Frontier with its 2.5L four-cylinder returned a similar 19 MPG city and 23 MPG highway. Are you willing to sacrifice some fuel economy for Toyota’s legendary reliability? It’s a frequent discussion point among Tacoma buyers. Looking at TACOMA MPG across all years can give you some perspective.

Tips to maximize efficiency

The 2.7L Tacoma prioritizes reliability over top-tier fuel efficiency, but there are steps you can take to improve MPG. Avoid aggressive acceleration and braking. Gradual acceleration helps the engine operate within its most efficient range, minimizing fuel consumption. Anticipate traffic flow to avoid unnecessary stops.

Regularly check your tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Maintain the recommended tire pressure specified on the sticker inside the driver’s side doorjamb. This simple maintenance task can improve fuel economy.

Minimize idling. If you anticipate a wait of more than a minute or two, turn off the engine. Modern engines consume very little fuel during restarts, so it’s more efficient to turn the engine off rather than let it idle. This is especially true with older powertrains like the Tacoma’s 2.7.

Keep up with scheduled maintenance. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine operates at peak efficiency. A neglected engine will consume more fuel. Make sure that you or your mechanic is using manufacturer-recommended lubricants.

Reduce unnecessary weight. Hauling around extra cargo increases the load on the engine, decreasing fuel economy. Remove any items from the bed or cab that are not essential. Emptying the bed after a weekend project can make a small but measurable difference.
