Just did an oil change on my Girlfriend's Jeep Patriot 2009. She bought the car 5 years ago with 63,000 on it. It now has 108,000. She's been taking it to jiffy lube and been driving it 8,000 miles on whatever they put in (considering they charge her $30, I bet it's conventional). We got her Pennzoil Platinum 5w-20 and a FRAM Ultra, XG10060. I've got a couple of questions for everybody: Attached is a photo of the inside of the fill cap, it was a little sludgy. Is that something to be concerned about? If so, what should I do about it? What OCI would you run? Would you double stint these filters?
Background: She drives around town a bit, but there aren't a ton of lights here in CoMo. She'll hit the interstate for a 30 min drive twice a week, 2-hour drive once every other month. Probably 65/35 highway-city split. 5w-20 is the only oil the manual allows. Her car is never garaged. She says the car needs to last her through Law school, 5 more years. She's currently putting ~19,000 miles on it a year.
