How Can I Improve Gas Mileage In My Ford Mustang?

Why is your Mustang mpg a mystery to some? Even with the growing trend of hybrid and electric vehicles, loads of gearheads just love the roar of a classic Ford Mustang, powered by good ol' gasoline. It's all about the thrill and simplicity, right?

But hey, even Mustang enthusiasts have pondered about optimizing fuel consumption. Whether it's due to the changing seasons or just the way your pony is purring, fuel efficiency is on the mind.

So, why would a Mustang owner want to save on gas? Simple: more miles per tank, a little extra cash in the pocket, and longer, uninterrupted cruises down the highway.

Stick around as we dive into the reasons behind varying fuel consumption and how to get more bang for your buck with your Mustang.

Key Takeaways:

  • Gasoline engines might guzzle a bit more than their diesel counterparts, but hey, there's a certain charm to them.
  • Want the best out of your Mustang? Stick to recommended speeds, engage that cruise control, and if your model's got it, flick on that ECO-Mode.
  • A well-maintained Mustang, especially when it comes to spark plugs, filters, and oil, is gonna make your ride smoother and your fuel consumption better.
  • Modern Mustangs are like a tech wizard's dream. They're loaded with sensors that can pinpoint if something's making your ride drink more fuel than it should.

Which Ford Mustang variant gives the best mpg?

Several factors influence the fuel consumption of the Mustang. It’s not just about the engine's size or the number of cylinders and valves. There's an old belief that bigger engines eat up more fuel, but that's not always the case.

Smaller engines do have their advantages due to fewer cylinders and less fuel per stroke. But on the flip side, a beastly engine can also be efficient. A powerful engine can get the wheels turning quicker, meaning less effort and less gas.

Then again, powerful Mustang engines, given the right conditions, can also be fuel-efficient. If the engine's got the muscle, it can move the car effortlessly, saving on fuel. Combine a strong engine with a well-designed chassis, and you're golden.

Gasoline vs Diesel: Who takes the crown for efficiency?

Alright, so the fuel consumption chat. Diesel engines might be efficient, sure, consuming about 20-30% less than gasoline ones. But, the Mustang's roar? That’s gasoline, baby.

While diesel has torque and is great for heavy lifting, gasoline engines, especially in a beast like the Mustang, are all about speed and power.

Diesel’s efficiency comes from its fuel properties. But here's the catch: gasoline has that unmatched acceleration and dynamic feel.

So, it boils down to this:

  • If you're all about the thrill, the speed, and that unmistakable Mustang growl, gasoline’s your pick.
  • But, if it's efficiency and torque you're after, maybe, just maybe, consider a diesel (though, why you'd want a diesel Mustang is beyond me).

Revving Up the Fuel Mileage of Your Ford Mustang

Tweaking fuel consumption? Well, that can be a hit or miss depending on your Mustang’s model year and the conditions you're driving in.

We've got a few general tips for ya. Give them a shot, and you might just notice your Mustang sipping, not guzzling, its fuel.

Stick to the Speed Limit

Love the rush of speeding up? Well, don't be shocked when your Mustang guzzles more gas than usual. Running the engine at high speeds means burning more fuel. But, just so we're clear, cruising like a snail at 20 mph won’t exactly do wonders for your fuel economy either.

So, what’s the sweet spot? Each Mustang model has its ideal cruising speed. Stick to that, and your engine will be more sip-friendly. You'll usually find this info on your dashboard, and if you're lucky, it might even be on the car's HUD.

Embrace Cruise Control

If your Mustang's rocking cruise control, use it on those long, open road trips. The system manages the fuel input, ensuring efficient consumption. So, fewer pedal pushes mean better fuel mileage.

Toggle That ECO-Mode

If your Mustang's got an eco mode, flick it on. It'll optimize performance and switch off what you don’t need. Better for the environment, and for your pocketbook too.

Smooth Acceleration is Key

Gun it and your Mustang drinks up the gas. Take it easy on the pedal. Smooth and steady wins the mileage race. Just picture a coffee cup on the dash – you wouldn’t want to spill it, would you?

Minimize Idling

Your Mustang might be purring softly while idling, but it's still drinking up fuel. Longer idle times? More wasted gas. If you foresee a long wait, might be a good idea to shut it off.

Don't Play Stop-and-Start in Traffic

Some folks think constantly shutting off and restarting in stop-and-go traffic helps save gas. Not so much. In fact, frequently restarting might make your Mustang thirstier and wear out your starter faster.

Here’s a tip: if you're facing a short wait, like at a traffic light, keep the engine running. But if you're stuck in one of those never-ending traffic jams, you might wanna consider turning it off.

Remember, with a car as iconic as the Mustang, it's about the ride. But a little fuel efficiency? That's just the cherry on top.

Lighten the Load on your Ford Mustang

Okay, let's be real. Sometimes, you gotta pack your Mustang with some gear, especially when hitting the road for a cool trip. But if you’re just cruising around town? Maybe drop that extra weight.

Extra weight in the trunk? More fuel's getting burned. So keep it lean. Empty out unnecessary stuff, and your Mustang will thank you with better fuel economy.

Those Tires Better Be Right!

Remember this: Your tires are literally where the rubber meets the road. If they’re slacking with low pressure, your Mustang’s gonna feel it. And by that, I mean you're gonna burn more fuel. Check those pressures!

Smart AC Use

Look, I love staying cool as much as the next guy. But if you're riding in the Mustang and it's already cool inside, maybe give the AC a break. It’ll save you some gas. When you start to feel a little toastier, crank it up again.

Limit Power Hungry Features

If you're almost running on fumes and need to get to the next gas station, consider turning off some of the power hogs like heaters, lights, and even the AC. But hey, let's not get crazy – always keep those headlights on at night.

Keep Your Mustang Pristine

Your Mustang’s like a fine watch. It’s gotta be well-maintained to keep ticking (or purring) efficiently. Here’s the lowdown:

Spark Plugs

If those spark plugs aren't doing their job, your Mustang isn't going to be at its best. Get them checked, replace if necessary, and enjoy a smoother ride.


Your Mustang’s engine needs to breathe, and clean filters make all the difference. Change them out regularly for optimal performance.

Engine Oil

Oil's like the lifeblood of your Mustang. Keeping it fresh ensures everything runs slick and smooth. Regular changes mean better performance and efficiency. Stay on top of it!

Overall condition of engine components

Engines: they get a bit tired over time, much like an actor after a few seasons of a hit TV show. The mighty roar of the Ford Mustang's engine isn't immune to this. A little wear and tear here, a bit of lost power there.

It doesn't take Joey Tribbiani to tell you that if your Mustang is chugging more fuel than usual, despite you playing by the rulebook, something might be up. And by "up", I mean worn out. Here are a few classic examples:

  • Cylinder-piston group wear. An engine's like a good coffee - it needs the right grind. If things aren't smooth inside, you're looking at a thirsty Mustang;
  • Valve wear. Kinda like when your apartment door doesn't shut right. It doesn't seem like a big deal until you're heating the whole hallway. A leaky valve can send your fuel efficiency south;
  • Wear root liners and crankshaft backlash. The Mustang's crankshaft shouldn't be doing the cha-cha-slide. If it's swaying side to side, you're burning extra fuel.

Too rich mixture

The Ford Mustang ain't a salad - but it still cares about the mix. We're talking fuel and air here. Too much of the liquid gold and you're running rich.

If your Mustang sounds like it's got a frog in its throat every time you step on the gas and there's more smoke than a backstage rock concert, you've probably got a fuel-heavy mix. This could be because of a diva-ish pump or maybe an injector that's past its prime.

Is your Mustang trying to tell you something?

The latest Ford Mustangs are pretty chatty with all those sensors and lights. It's like they're constantly sending out S.O.S signals. If your dashboard's lit up like a Christmas tree, you might want to dig deeper.

Hook up an OBD-2 gizmo and see what's up. Maybe a sensor's having an off day and it's throwing off your fuel mix.

Turbo-charge your Mustang's brain

Modern rides like the Mustang come with some pretty neat electronics. But if you want to outsmart the smart, you're gonna need a programmer. Think of it as giving your Mustang a PhD in fuel efficiency.

Sync it up with your phone and play around with the engine settings. Dial it down a bit, and you'll see the gas needle move slower than usual.


Whether you're cruising around Central Perk or burning rubber on the open road, there are ways to keep your Ford Mustang's thirst in check. Some are about the hardware, while others just need a bit of TLC. Either way, keep these tips in mind, and you'll be miles ahead.
