Asked by Apr 20, 2016 at 01:42 AM about the 2015 Dodge Charger SXT

Question type: General

I just bought a 2015 charger sxt with a 3.6L engine & I
was wondering what's the best type of gas to use. 87,88,
or 89? This is my first charger so I'm kind of iffy as to what
has to put in her.

It should tell you in the owners manual. You should be able to run regular unleaded in it, but the higher octain fuels run cleaner. The premium here in my neck of the woods does not have the ethanol in it that gums up internal parts of the fuel system. But if you throw some fuel injection cleaner in the fuel system once in a while, you can run the lower octain fuel.

1 out of 1 people think this is helpful.

A HUGE marketing research study, Optimized chemical mechanism for combustion, the MIT researchers deemed AKI — and more specifically, MON — to be an outdated measure of engine performance, originally designed to apply to older, carbureted engines rather than modern, fuel-injected engines. To bring the octane rating system up to date, the team considered doing away with MON, and basing engine performance solely on RON. " Virtually nothing is gained by filling up with a premium or more expensive grade of fuel than the vehicle manufacturer has recommended, the experts say. And many of the same experts explain that drivers may not lose much performance from their cars by using a lower grade of fuel than recommended by the car manufacturer. There is little difference in energy content of regular versus premium gasoline. They both contain about 111,400 British Thermal Units of energy per gallon. The price difference, however, between the fuel grades is anywhere from 20 cents to 40 cents, depending on where you live in the United States. The experts' consensus goes against the long-held belief by thousand of drivers who fill up with premium only, or on every third or fourth trip to the pump. The idea is to fill up with premium every so often to clean out the engines or rev up the performance of older engines. But according to the experts, this practice is like tossing quarters in a wishing well, since most engines are designed to operate on relatively low-octane regular unleaded gasoline."


You can read stuff all day long on what you should run, what the factory says you should run, but here's the best way to find out, run each grade of fuel for at least 3 fill ups, use top tier fuels and stay with the same station so you can get a good read, monitor the fuel mileage on each tank, at the end of the trial recheck the MPG's per tank on each grade of fuel and the one that gives you best fuel mileage is the one to use. HTH


I never checked mileage on my motor but it needs the higher octain fuel to run good since it is pushing 400 hp. But of course that is different than the standard automobile out on the road. I do notice a difference in the power my moped has running premium in it tho. Ethanol just causes problems unless you keep up with a fuel system cleaner.
