How to Change the Transmission Oil in a Chrysler 300

Updated April 17, 2017

Rather than paying the dealership or an oil change shop to change the oil in your Chrysler 300, you can do it yourself and save money. For roughly £9 to £13 you can buy oil and an oil filter, the two most necessary items for completing an oil change.

Buy five quarts of new oil for the V6 Chrysler 300 or seven quarts for the V8. The Chrysler 300 takes 5W-20 oil in any brand. Synthetic oil is better for newer cars, but you can use conventional oil as well. If buying synthetic, remember it must also be 5W-20.

Buy a new oil filter. Many brands will work; the STP S16 oil filter works for all models of the Chrysler 300, including the HEMI.

Find a place to complete the oil change. You can do the oil change at an auto hobby location that has a car lift or in your own garage.

Unscrew the bolt on the oil tank underneath the Chrysler 300 with a socket wrench. Put an oil dripping pan underneath the oil tank to catch the oil. The oil will drain as soon as the bolt is removed. The oil will take 3 to 5 minutes to completely drain.

Clean the excess oil off of the oil tank with a rag and screw the bolt back on the tank with a socket wrench.

Locate the oil filter underneath the car and unscrew it.

Screw the new oil filter into the same location.

Pop the hood and unscrew the cap off the top of the oil tank.

Put a funnel into the top of the oil tank and pour oil into the tank. Do not overfill the tank.

Screw the cap back on the oil tank when you are done filling it and close the hood.

Record the oil change in a car maintenance journal. Change the oil again in 3,000 miles.


Wear old clothes when changing the oil.
