To find the answer, we’ve gone through the owners’ manuals of the Dodge Chargers that were produced in 2005. Here’s a quick answer:

Dodge Chargers built between 2005 – present with a 2.7L, 3.5L, 3,6L, or 5.7L engine are designed to use high-quality unleaded regular gasoline with an octane rating of 87. The 5.7L engines can also use gasoline with an octane rating of 89. Dodge does not recommend premium gasoline because it does not provide any benefit.

What Types Of Gasoline Can And Can’t Be Used?

Besides regular/conventional gasoline, there’s a wide variety of types of gasoline that are available on the market today. For many of this gasoline, Dodge has indicated whether the Charger can have this kind of gas or not. Let’s take a look.

Reformulated Gasoline

Reformulated gasoline is a newer type of gasoline that is designed to burn more cleanly than conventional gasoline. This means it reduces smog-forming and has less toxic pollutants. RFG is specifically used in areas of the United States where air quality is a problem.

Dodge recommends the use of reformulated gasoline for all Dodge Chargers that were produced since 2005. According to Dodge, reformulated gasoline will provide excellent durability and performance of the 2.7L, 3.5L, 3,6L, and 5.7L engines and all their parts.

Gasoline/Oxygenated Blends Or E-85

In many cases, fuel suppliers also provide oxygenated blends of gasoline. One of the most popular mixes is regular gasoline with ethanol. E-85 is a common example, where 85% of ethanol is mixed with 15% of regular gasoline. Cars that use this mixture normally have lower miles per gallon but reach higher horsepower and torque numbers.

Dodge strongly advises against using oxygenated gasoline blends with an ethanol percentage of 15% or higher in the Dodge Charger. E-15 to E-100 fuel and all numbers that fall in between are therefore not recommended. Using fuel with 15% or higher ethanol will result in the car driving in lean mode, poor drivability, a difficult cold start, check engine lights, and engine damage. It may also void the warranty of your car.

Furthermore, it’s good to know that Dodge indicates in the owner manual that they are okay with you using fuels with 10% ethanol in the 2005 – 2010 Charger. However, in the owners’ manuals of the 2010 – 2015 Charger, they state that using fuels with 10% ethanol is strongly advised against and shouldn’t be done. From 2015 onwards, they bumped this number up to 15% ethanol.

Gasoline With Added Materials

Some types of gasoline have added materials such as detergents, corrosion, and stability additives. This makes sure that the engine stays in its best condition while also providing the longest lifespan. Dodge recommends these so-called Top Tier fuels for all Dodge Chargers.

You can find a station that serves these types of gasoline at toptiergas.com.

Gasoline With MMT

Gasoline with MMT is prohibited in Federal and California reformulated gasoline because it reduces spark plug life and reduces emission system performance. Dodge recommends using gasoline without MMT for all generations of the Dodge Charger.

Please note that MMT levels are not always indicated on fuel pumps. If you want information about MMT, you should ask the supplier or the gas station.

What If I Hear A Knocking Noise From The Engine After Refilling?

In the owner’s manual of the American/Canadian-made Dodge Charger, it’s said that hearing a slight knocking sound from the engine is not a cause for concern and completely normal if you’ve used the right kind of fuel. If you hear a loud knocking noise, you have to stop the car immediately and visit a dealer. In this case, you’ve likely used gasoline with a lower octane number.

If you use gasoline with a lower octane number, this will intensify the knocking sound and cause the car to stall or hesitate when driving. Using this kind of fuel in your vehicle may void the New Vehicle Warranty.
