The 2017 Dodge Challenger requires 87 octane regular unleaded gasoline. Over time, car parts can deteriorate, so it's important to replace the fuel filter every 30,000 miles to avoid performance issues. Ensuring optimal fuel combustion is key to maximizing fuel efficiency. Keeping your gas tank well-maintained is crucial to prevent potential problems such as a loose tank, faulty control valve, or gas leaks that require immediate attention. Dealing with a stuck gas cap can also be a challenging situation.
The maker of the Challenger suggests using premium gasoline for the bigger engines, such as the 5.7L manual and the 6.4L, for best performance. However, these engines can still operate on regular gasoline. Smaller engines will perform equally well on regular or premium fuel.
