I have only 30,000 miles on my 2006 Jeep Commander.

I looked up the maintenance requirements listed in the owners manual, and was surprised to find the following: 'B' service schedule is for vehicles that: day or night driving @ 32degrees F or less, stop and go driving, excessive idling, dusty conditions, short trips under 10 miles, 50% of driving at highway speeds @ 90degrees, towing, carrying heavy loads, police, taxi, delivery use. If ANY of these apply, Jeep recommends you go by 'B' schedule. (Does anyone qualify for 'A' schedule?) which at 30 k recommends what you list minus induction services (they recommend check air element , replace if necessary, and in addition to your list they recommend oil and filter (if over 3 months since changed I believe), rotate tires. Wow, I didn't think any vehicles required a plug change at 30k anymore. The most expensive plugs I could find were NGK platinum at $10 each. Don't know how hard they are to change, but even at that price (other brands just as good and less expensive) you would save $119.95 on plugs alone. 2 suggestions, check another dealer (I just priced 30k service for my 07 F-350, one dealer $425, another $575, parts/fluids to do it myself $125. So shop around, a private garage would be less than a dealer, or invest in a great service info manual (ask, and I'll tell you which I recommend), and do it yourself. If the Jeep is still under some type of warranty, make sure to keep all receipts to show the work was done, or when it's time to sell it, good idea to have records to show a potential buyer.

The differential and trans service is a must, but the induction and spark plugs can wait till the 60k. There are 2 different types of service schedules. Regular and severe. The dealer will always recommend severe driving service.
