First WJ! General questions!
Alright everyone, this is my first WJ and I'm excited to get my hands on one. I currently have a 2011 5.0 fx4 f150 and now this 2004 grand Cherokee Laredo special edition. I actually went to pick up a buddy of mine today who had dropped off his jeep for service at the dealer and happened to spot a trade in sitting in the lot. I've always heard good things about the 4.0 I6 and thought it would be nice to have to take some miles off my truck. The jeep is clean, exterior is amazing. Minor minor scratches, no body rust, and paint looks great. The frame is in great shape and the interior is immaculate. So either the dealer did a great job or the truck is in great shape lol. Either way, I figured for the condition of the body and the price I could always throw another 4.0 in it. The truck currently has 201k on it and I got it for 2800 cash. Now my question is, which oil is best to use on this block over 201k.. I don't want to assume it's been using a full synthetic and I see the manufacturer specifically printed 10w30. I've read a little bit here and there saying mobile 1 high mileage, gtx, or rotella. Truck does have a light tapping when started but that seems to be a common issue. I know this topic has been a great debate just trying to find out what's best for this amount of miles. This engine is new to me, I've had success with 2 5.4L 3v triton motors by ford one with 343k when I sold it and still running today and another with 270k also still running, and I only used the fords recommendations. If I can get another 50-70k out of this jeep ill be a happy happy man and well satisfied jeep owner. Also grabbed a mopar filter as well. Second question, how exactly does this quad-tracII work? Is it essentially awd?
