Good evening all, I've been wondering if I should change the oil on my Saturn. Right now it has Mobil Clean 5000 in it and I changed it this past January. It has about 3,300 miles on it. I haven't done much driving since then as I've been unemployed, but I recently started working again. I will be driving about 36 miles a day (18 miles each way highway). Most of the miles on the oil have been a mix of highway trips and around town in less than 3 or 4 mile trips. The filter on there is a Purolator. My concern is more about the time it has spent in the sump rather than the miles. I have been commuting to work now so I do believe I have at least been burning off the moisture that accumulates. If you all recommend a change, I have a fresh case of Formula Shell and another Purolator filter. Otherwise, I have no problem running it out to 5,000 miles if folks don't foresee a problem running out my current fill. Thanks. - Oil OCD Guy P.S - This car has an OLM dummy light and it hasn't reset yet. Usually likes to go off around 5k in my experience.
