Hey folks, I recently did the the first oil change on my 2013 SXT and used Mobil 1 5W-30 full synthetic because that weight of oil seemed to be what people here recommended for the 3.6 when I was nosing through threads on the subject. Like an idiot, I never really read through my owners manual and noticed that it said to use 5W-20. Apparently the oil weight changed for the 2013 models, or so I'm assuming. I haven't had any problems, so I'm guessing this is ok. Any suggestions or am I fine to continue using 5W-30? I live in Ohio, it's colder than (blank) in the winter and miserable in the summer, if that makes a difference.
