There are many threads about oil for the 1.4 but couldn't find much on the 2.0. I have 2 dealers in the area and one says I have to use full synthetic and the other says I can only use a synthetic blended oil. Called Chrysler help line and they didn't really have an answer for me. I was going to use mobil 1 full synthetic. I just want to use the oil recommended for my 2.0. Please help.
