The standard oil for a 2010 Chrysler 300 V6 is SAE 5W-30 synthetic motor oil that meets Chrysler’s MS-6395 specification. In some circumstances, the owner's manual may permit 5W-20; always verify the exact grade in your manual or on the oil filler cap.
The 2010 300 offered two V6 engine choices: a 2.7-liter and a 3.5-liter, both using the same broad guidance but with variations that can affect recommended viscosity. This article outlines the correct oil for each engine and how to confirm it for your vehicle.
Engine options and oil compatibility
2.7-liter V6
Oil that meets Chrysler MS-6395 with a viscosity of 5W-30 is typically recommended for the 2.7L V6. If the owner's manual specifies 5W-20 for your climate or driving conditions, you may use that grade when approved by the manual. Always prefer a full-synthetic or synthetic-blend oil for long-term protection.
- 5W-30 synthetic or synthetic-blend oil meeting MS-6395
- 5W-20 only if the owner's manual explicitly allows it
In short, follow the manual and use the grade specified; when in doubt, 5W-30 is the safe default for the 2.7L engine.
3.5-liter V6
For the 3.5L V6, the common recommendation is 5W-30 synthetic motor oil meeting MS-6395. Some climates or dealer guidance may permit 5W-20 if explicitly allowed in the manual. Use a high-quality synthetic or synthetic-blend and replace according to the maintenance schedule.
- 5W-30 synthetic or synthetic-blend oil meeting MS-6395
- 5W-20 only if the owner's manual explicitly allows it
Again, the decisive source is the owner’s manual; if it calls for 5W-30, that’s the choice you should follow.
Summary
For a 2010 Chrysler 300 V6, the typical requirement is 5W-30 synthetic oil meeting MS-6395. Always check your owner’s manual or the oil filler cap to confirm the exact specification and viscosity for your specific engine and climate. If the manual permits 5W-20, you may use it in cold conditions or for fuel-economy considerations, but when in doubt, stick with 5W-30.
