Is the 2015 Mercedes-Benz ML350 4matic good on gas?

At up to 19 MPG combined, the 2015 Mercedes-Benz ML350 4matic is about average for a Standard Sport Utility Vehicle 4WD — that class averages about 18.9 MPG across 1,684 EPA-tested versions, so it's middle-of-the-road for its size.

Real-world MPG vs the EPA number

The EPA figures above come from a standardized dynamometer test, not the open road — real-world MPG typically runs a bit lower depending on your driving, climate and terrain. That's true of every car on this site, old or new.

EPA updated its fuel-economy equations again for model year 2017 — mostly affecting hybrids and turbocharged engines — and recalculated 2011-2016 ratings to match, in some cases 1-2 MPG lower. The number above already reflects that update.

At today's AAA national average price — $4.68/gal for premium gas as of 2026-07-05 — the most efficient trim runs about $3,695/year (roughly $308/month, about $24.63 per 100 miles) at the EPA's assumed 15,000 miles/year, using an estimated 789 gallons a year. We don't estimate a cost-per-fill since exact tank size isn't in the public EPA dataset, but the per-100-mile figure scales to any tank. Current national average gas prices →

Where the EPA lists premium, that’s the fuel the maker specified for the mileage test — many such engines run on regular with slightly less power/MPG. Whether premium is required or just recommended is an owner’s-manual detail the EPA dataset omits, so we don’t guess it.
