13 MPG combined isn’t going to win over any Prius drivers, but for the 2015 GMC Savana 3500 2WD Passenger van with the 4.8L V8, it’s the trade-off for what it offers. This vehicle isn’t about fuel economy; it’s a workhorse and a people-mover. Businesses, churches, and large families choose it for its space, durability, and ability to haul significant loads.

City and highway performance

The EPA estimates 11 MPG in the city and 17 MPG on the highway for this Savana configuration. The city figure reflects urban driving’s stop-and-go conditions and the van’s weight. The highway MPG is better, but still relatively low because of the Savana’s boxy shape and aerodynamics. Don’t expect much better in real-world conditions.

Annual fuel cost

The EPA calculates the annual fuel cost for this 2015 GMC Savana 3500 2WD (Passenger) 4.8L 8-cyl at $3,350. This is based on driving 15,000 miles per year and using national average fuel prices when the rating was established. Fuel prices can change this number. Expect to pay more if you drive more than 15,000 miles annually, or if fuel prices are higher in your area. The government provides this to compare vehicles, but individual costs will vary.

Real-world expectations

Owners of the 2015 Savana 3500 Passenger van rarely see numbers far from the EPA’s estimates, especially with passengers and cargo. Aggressive driving, frequent idling, and neglecting maintenance will lower fuel economy. Some owners might get slightly better highway numbers with a light load and gentle driving, but don’t count on consistent improvements beyond the official numbers.

How it compares

Competitors like the Ford Transit 350 passenger van with its base 3.7L V6 often get slightly better fuel economy, around 14 MPG combined. The Nissan NV3500 HD also mirrors the Savana’s numbers, with some trims dipping below 13 MPG. In this segment, fuel efficiency isn’t a differentiator. Buyers needing a lighter-duty van might consider the Ram ProMaster 1500, which can achieve around 17 MPG combined with its V6 engine. However, the Ram sacrifices some of the Savana’s reliable build quality and towing capacity, which is a dealbreaker for many Savana buyers. Look at SAVANA MPG across all years for more information.

Tips to maximize efficiency

Regular maintenance is critical. Ensuring your Savana’s engine is tuned, the tires are inflated, and the air filter is clean can improve fuel consumption. Neglecting these things will worsen fuel inefficiency, especially for a vehicle of this size.

Avoid unnecessary idling. The 4.8L V8 uses a lot of fuel while idling, especially with the air conditioning running in hot weather. Turn off the engine if you’ll be stationary for more than a few minutes.

Drive smoothly and watch traffic. Quick acceleration and hard braking waste fuel. Maintain a steady speed and anticipate traffic to maximize momentum and minimize fuel consumption. Use cruise control on the highway to maintain a consistent speed.

Carry only what you need. The more weight, the more fuel you burn. Remove unnecessary cargo to reduce strain on the engine. The Savana is designed to haul, but a lighter load will improve fuel economy.

Plan your routes. Avoid congested areas and routes with stop-and-go traffic. Choose routes that allow for more consistent speeds. Planning can save you time and money. Research and compare this to all Gmc fuel economy data.
