I just noticed that Dodge calls for 5w20 in the 2005 Neon but 5w30 in the 03. Can I use 5w20? Did they change the oil pump or something? Would I even notice a difference in mileage? I plan on keeping this car till the wheels fall off.
Well, I have already posted a question concerning 5w20 and gotten some great replies. From what I have heard there would not be any problem using the 5w20 in your vehicle. I really like what I see so far from the Motorcraft 5w20 Synthetic Blend. You will probably have other input but that is my take on it. Best of luck.
