Here is a basic maintenance question. I have a Intrepid that recommends 10W-30 under normal use; however, the 5W-30 viscosity is recommended only for freezing and colder. My dealer dumped 5W-30 in it for some stupid reason. My question is do I need to get on the phone and fight them to use the correct oil or can it tolerate this for 3K miles no matter how long it takes to get to that interval.
