Generally the 5W-20 is specified for engines with variable valve timing. I would have guessed that that feature is in both model years.
The newer engines use tighter tolerances and can use a lighter oil which should help very slightly with gas mileage (i.e. less viscosity = less friction).Jaime said:Ok, my 2012 T&C 3.6 requires 5w30 oil, my 2013 200 3.6 is requires 5w20...
Is there a differance beacuse of the model year?
