It’s recommended that you change your Chrysler 300’s oil every 3,000 to 5,000 miles for conventional oil and every 7,500 to 10,000 miles for synthetic. You’ll want to check your owner’s manual to determine the correct grade and amount of oil you’ll need.
Healthy oil maintains proper lubrication of the engine, which in turn regulates its temperature and improves fuel efficiency. Dirt and debris accumulate in your oil over time. This can damage your engine if left too long, so it’s important to change your oil regularly to avoid expensive

How often does a Chrysler 300 need an oil change? 

You’ll need to change your oil and filter every 3,000 to 5,000 miles for conventional oil or 7,500 to 10,000 miles for synthetic. 
Waiting too long can lead to a dangerous build up of sludge and debris, so make sure you
perform regular maintenance
on your Chrysler and top up the oil if it appears low. 

What kind of oil does a Chrysler 300 need? 

A Chrysler 300 generally needs 5W-20 synthetic oil with API SN or API SP specification, but this can vary depending on the year, mileage, and climate of your car. 
Check your manual to see what your car needs. The following multigrade oils are recommended to keep the oil adaptive to outdoor temperatures
  • Cars under 75,000 miles—OW-20, 5W-20, 5W-30, 10W-30
  • Cars under 100,000 miles—5W-30
  • Cars in hotter climates—5W-30, 10W-30
  • Cars in colder climates—OW-20, 5W-20
Note that the Chrysler Multiple Displacement System (MDS) has particular viscosity requirements. Be sure to use an API-certified SAE oil with the viscosity noted in your manual to prevent damage to this system. Using the wrong oil can also void your warranty.
Synthetic oil is encouraged, but you can also use conventional or mixed oil on a Chrysler 300. You’ll want to make sure it meets either the Chrysler MS-6395 or MS-9214 approval specified in your manual. Essentially, this indicates the product meets Chrysler’s “Material Standard” for use in its V6 or V8 engines.  
Key Takeaway The type of oil a Chrysler 300 needs will be noted in its manual. You’ll want to use the right viscosity to prevent damaging the MDS system.     

How much does an oil change cost for a Chrysler 300? 

The cost of an oil change for a Chrysler 300 will depend on whether you will take your car to a mechanic or perform the oil change yourself. 

Professional cost 

The average cost for a professional oil change on a Chrysler 300 ranges from $148 to $157. This total includes an estimated $35 to $45 in labor fees, along with about $113 for the filter and oil
Your mechanic will most likely use Chrysler MS-approved synthetic oil unless instructed otherwise, which can add to the total expense. 

DIY cost

Changing the oil yourself will save you money. One quart of 5W-20 or 5W-30 usually costs between $4 and $12. Five quarts costs up to $40

How to change the oil in a Chrysler 300 yourself 

What you’ll need 

  • 6 (3.6L) or 7 (5.7L) quarts of 5W-20 oil, or whatever your manual recommends
  • Chrysler 300 filter—make sure it fits your engine type (V6 or V8)
  • Oil filter wrench
  • Car ramp (or jack and jack stands)
  • 3/8 in. ratchet set (1/2 in. for 3.6 L engine) 
  • 3/8 in. torque wrench (1/2 in. for 3.6 L engine) 
  • Drain pan and rags
  • Oil funnel 
  • Pick set
  • Gloves and eye protection

1. Warm up the engine

You’ll want to run your engine for about five minutes before you get started. This is to make the oil less viscous, which helps clear out the old oil more thoroughly. 
If you’ve been running the engine much longer than this, you’ll need to let it cool to prevent burning yourself. 

2. Secure the vehicle 

Put the car ramps under your front tires and drive your vehicle onto them—park and set the parking brake, then place blocks behind your back tires to prevent rolling. You can also jack your car if you prefer. 

3. Drain the old oil

Turn off the engine and open your hood. Unclip the engine cover, then go under the vehicle and remove the bolts holding the rear belly pan in place. Set the belly pan aside and place a drain pan under the drain plug. 
Carefully remove the oil drain plug and let the old oil drain into the pan. When it’s done, replace the oil plug by screwing it in first by hand, then with the torque wrench to get it tight. 

4. Remove the filter

On a 5.7 L engine you’ll remove the oil filter under the car—you can find it behind the steering rack. With the drain pan positioned underneath, use the oil filter wrench to unscrew it counter-clockwise. Check to make sure that the gasket, or O-ring, comes out with the oil filter. 
The oil filter is removed from the top of a 3.6 L engine. Lay down rags or towels around the filter, then unscrew the cap of its housing component clockwise—you’ll want to use the 1/2 in. ratchet. Remove the filter cap and then unsnap the older filter from the cap. 

5. Install a new filter

On a 5.7 L engine, fill the new filter with the proper oil and apply a coating of oil to the gasket ring with your finger. Screw the new filter in first by hand and then tighten it with the filter wrench just until it’s snug and secure. 
On a 3.6 L engine, remove the O-ring from the cap with a pick and replace it with a new one. Then snap a new filter into the cap and apply a coating of fresh oil on the O-ring. Put the new filter and cap into the housing component and tighten it first by hand then with the torque wrench. 

6. Pour in new oil 

Clean then take off the oil filler cap—on the top of the engine—and place an oil funnel into the opening. Add the specified amount of oil from your user manual and replace the cap.  

7. Check the oil levels 

Start the engine and let it run for about five minutes before shutting it off. Wait for another minute, then use the oil dipstick to check your levels—it should be within the marked fill lines. If it isn’t, add more oil and check again. 

8. Reassemble

Look under the car for any leaks. If it’s clear, reassemble the rear belly pan and bolts and restore the upper engine cover. 

9. Reset the oil change display

With the engine off and the car in park, press the “Start/Stop” button twice to run the car without starting the engine. On older models, turn your key in the ignition to the first “on” position. 
Press and release the gas pedal three times within 10 seconds. Turn off the vehicle and restart it. The oil change display should be reset—if it isn’t, repeat the previous steps.
