I'm confused too! ...So...
here's where I'm stumped.
I went to my dealer and he was helpful in finding the oil filter and told me that I need 0-20 f. Syn. Ok. Thank you...
Then saw the post that reads 5-20 f. Syn.
So I checked under the hood and it reads 5-20 f. Syn.
Im so confused.
I read your intro thread that states you have a "1.4 Multiair sxt" ... which would mean that you have a 2013 Dodge Dart SXT (with the 1.4L MultiAir Turbo engine) ... because for 2014, the SXT model is only available with the 2.4L Tigershark MultiAir II normally aspirated (non-turbo, non-supercharged) engine.
So if you indeed do have a 2013 SXT with the 1.4L MultiAir Turbo engine (i.e., the engine that this thread is about), you need to use 4 quarts of 5W-40 full synthetic oil.
But if you actually have a 2014 SXT with the 2.4L Tigershark MultiAir II normally aspirated (non-turbo, non-supercharged) engine, then you can indeed use either 5.5 quarts of 0W-20 full synthetic oil (as recommended in the 2014 Dodge Dart Owner's Manual) or 5.5 quarts of 5W-20 full synthetic oil (as noted under your hood).
