Just got my first oil change done yesterday, and about fell over when I looked at the receipt and saw it was $177. How long can I expect to go between full synthetic oil changes? Also is it wise to just change it myself going forward and save a couple bucks? How will this affect my warranty if I change my own oil?

I have driven my 2008 Overland Diesel 100k miles. I change the oil w/Mobil One every 10K miles. Sears charges $109. Thats a penny a mile. My Subaru Outback I change every 3 -4K miles w/non synthetic oil. Sears charges $32. Thats a penny a mile. The oil filter is not easily accessible w/o a lift, and 10 quarts of oil makes a huge mess if you don't have an adequate catch basin.

I know about LOW SPAsh and DPF poisoning but the way they presented it is like you do not have choice - use Chrysler oil (relabeled Pennzoil probably) or Pennzoil Ultra Euro 5W-30 (good luck finding it). I can assure you that the oil weight makes difference on fuel economy unless you run dry sump. I will not use Mobil 1, but I would prefer Pento High Performance II 5W-40, maybe I am old school but I like little extra piece of mind.
For you info you can check this spec sheet and find many more oils that are LOW SPAsh just like Pennzoil (which is included in it).

Use Mobil One or any other full synthetic. It lasts 10K miles.
