I have a 2017 Pacifica with the 3.6L engine. It calls for 0W20 oil in the manual, and nothing else. My car has been at the dealer for a couple days getting the recall repairs done. They gave me a 2018 Dodge Town & Country 3.6L rental until they finish my car. I checked the oil in the Dodge and found that it calls for 5W20 oil. And the manual for the 2018 Dodge says that "Mopar SAE 5W-30 engine oil approved to FCA Material Standard MS-6395 such as Pennzoil, Shell Helix or equivalent may be used when SAE 5W-20 engine oil meeting MS-6395 is not available." So what is the difference? The engines are the same, no? Yet the Dodge uses 5W20 and says 5W30 is acceptable, yet the Chrysler calls for 0W20 only (Lubricants which do not have both the engine oil certification mark and the correct SAE viscosity grade number should not be used.). CAFE strikes again?
