To Premium or Not to Premium—What Fuel Does Your Dodge Need?

So, you just bought a Dodge car and it’s finally time to fuel up—you look at your three options on the gas pump and might naturally reach for premium fuel. However, is this type of gas always needed? The answer might surprise you, as even performance models like the SRT variants might have alternatives. To learn why you likely don’t need premium fuel, stick with us today—also, visit us at Gill Chrysler Dodge Jeep RAM in Madera, CA, to test drive your favorite performance-fueled vehicles, like the Dodge Challenger SRT.

But First…What’s the Difference Between the Fuel Types?

When you’re at the gas station, you’ll usually see at least two different types of fuel—with regular gas having an E85 underneath the button and premium gas with an E91 or E93 listed on the button. But what do these numbers mean? In short, these numerals refer to the ethanol content in your gas—and in theory, higher ethanol ratings can withstand higher compression levels. So, usually, you’ll want to fill your performance models with premium gas to reduce the odds of a detonation happening at an inconvenient time.

However, Dodge vehicles are a special case, as E85 fuel usually works across many vehicles in the lineup. But can you fill up with 91 premium gas? Technically, you can, but you’re not receiving any real benefits and you’re paying roughly 50 cents more per gallon, which is money you could spend elsewhere at the end of the year, like cool new OEM accessories for your ride.

Wait…Even the Charger and Challenger Don’t Need Premium?

Yes, you read that correctly—almost everything from the Challenger SRT to the base Dodge Charger fuel types can work with E85 ratings. But why wouldn’t one of the world’s most powerful production muscle car not need premium gas? In short, models like the SRT trims provide stronger knock resistance when compared to other performance vehicles (when fuel, pressure, and heat mix and cause temperatures to rise too high for your powertrain). The longer answer has to do with the sensors in the motor detecting the alcohol levels in the fuel before it reaches the injectors, which allows the motor to alter the pressure and ignition timing to better adapt to the situation.

Either way, you can still use higher ethanol gas levels if you prefer—and as a rule of thumb, always check your manual for OEM-specific recommendations.
