Premium is required
What color is premium gas
I used regular gas in my 2009 Murano. Ocassionally, I use the premium when I have extra cash.
you can use regular or premium
higher OCTANE!
i am guessing you should use premium gas for a Chrysler 300. Regular is ok unless you have a SRT8.
For a real answer check out this http://www.cartalk.com/content/features/premium/questions.html Their answer is a qualified yes, it is OK to use regular in modern cars. But read the all the details in the link above.

It is always okay to switch between regular and premium gasoline. With that said, it depends highly on the make of your engine whether or not your car will actually benefit at all from the use of premium gasoline. Make sure to look in your car's manual before you switch to see if your car can benefit for from the switch.
Use what the manual tells you....regular gas.
unleaded
It doesnt require any work all you have to do is fill it up with regular gas.
BMW only takes gas rated at octane 91 or higher, and that is Premium at the gas station.
