Getting More From Your Mustang! E85 and Powering Your Pony Car

Hey Mustang enthusiasts! If you're like me, you can't get enough of that raw power and exhilarating performance that comes with owning a Mustang. It's the kind of car that makes you want to shout, "Yeehaw!" as you cruise down the open road. Well, hold on tight, because today we're diving into the world of E85 fuel and how it can supercharge your Mustang experience. 

Now, you might be asking yourself, "What is E-85?" E-85 is a high-octane fuel that's made primarily from ethanol. It's like the energy drink of gasoline, giving your Mustang that extra kick in the rear. With an octane rating of 100 or more, E-85 allows you to unleash more horsepower by cranking up the timing and boost. And the best part? It's often cheaper than premium fuel, saving you some greenbacks for those shiny new mods you've been eyeing.

Racing down the track, an E85 equipped Mustang can go faster on cheaper e85 fuel when compared to higher octane regular gasoline.


Finding E-85 fuel is easier than roping a wild stallion. You'll find it at many local gas stations, so you don't have to ride your pony too far to fill 'er up. Just search for "ethanol E85 near me" and watch the options pop up like prairie flowers after a spring rain.

Now, let's talk about how you can turn your Mustang into an E-85-drinking beast. Depending on the generation of your trusty steed, you'll need to make a few modifications to the fuel system. If you've got a first-generation Coyote Mustang (2011-2014), you'll need a minimum of 47lb fuel injectors and a custom tune to handle that E-85 goodness. Your factory fuel lines and pump can handle it without breaking a sweat.

For you proud owners of second-generation Coyote Mustangs (2015-2017), the process is a bit easier. If you're sticking with the factory intake manifold, you can run E-85 on the stock fuel injectors. Just make sure to get that custom tune to keep everything in harmony. But if you've upgraded to a snazzy intake manifold, you'll need those 47lb injectors to keep up with the increased airflow. Your Mustang will be flexing harder than a Shelby GT350 on a race track!

If you've got a third-generation Coyote Mustang (2018-2020), you're in luck. The good folks at Ford equipped these bad boys with direct injection and a whopping 16 injectors. That means you've got enough fuel delivery to support E-85 and some bolt-ons. Unless you're planning on adding some serious boost and horsepower, you can keep your fuel system as-is and focus on other mods. Yeehaw!

The sun sets in the distance behind the hills, still reflecting off the blue Mustang GT 500.

So, my friends, it's time to unleash the true potential of your Mustang. E-85 fuel is the secret weapon that can turn your pony car into a fire-breathing beast. With increased octane, more horsepower, and a cost that won't break the bank, it's a win-win situation. Advanced Fuel Dynamics has all of that you need, from the FlexFuel Kit with a dedicated E85 sensor, to upgraded fuel injectors, everything you need for all that additional power is at your fingertips. Just remember, E-85 burns through fuel faster than a Mustang on an empty stretch of road, so be prepared to quench that thirst.

Get out there, fuel up with E-85, and let your Mustang run wild. Whether you're driving a Shelby GT500, a Mustang Boss 302, or any other variation, this is your chance to take your pony car to the next level. Hold on tight, because the ride is about to get wild!

Until next time, keep the rubber on the road and the engine roaring.
