Well, I hit 30k miles this weekend, and one of my gifts was a gift card to Advanced Auto so I bought spark plugs, an air filter and new wiper blades. The spark plugs could not be easier to change. Even with taking my time, using anti-seize and some die-electric grease on the coil boots it only took me all of 20 minutes. You only need a T-30 torx socket and a normal 5/8" spark plug socket. Now I have two 5/8" spark plug sockets, one with the rubber plug holder insert and one without. I used the one with and duct taped the 6" extension to the socket (it wanted to leave the socket behind, and the plug hole is deep and narrow for getting pliers down there to pull it back up). Anyway, no problems with the old ones coming out. They were definitely worn too, they didn't have too many miles left to them (and the same for the air filter, very dirty and all on road miles). I used Autolite Copper Core's #5224 and a Purlolator standad air filter. I do plan on getting a K&N replacement filter too, but I figured I'd get a standard replacement for now until I order the K&N. This way I'll have a low mileage (in usage) filter to pop back in there when I have to clean/re-oil the K&N.

Anyway, two thumbs up for Jeep making this an easy service to perform.:smiley_thumbs_up::smiley_thumbs_up:

No plugs for me yet, but have changed the air filter a couple times, it could be a bit easier, lol, but not bad.

I thought with electronic ignition that plugs were fine to like 100K?

i can't get over how many people are changing their spark plugs at 30K ??? is Chrysler putting in such low quality plugs that you need to change them every 30K miles?

1) That's the recommendation in the service manual (30,000 MILES, not kilometers- 30K mi. translates to a but over 48K km; hence the Canadian recommendation of 50K km).
2) They're standard resistor type plugs. That's how long they last. I swapped mine at 25K and noticed an immediate improvement in throttle response. Word is that the platinum tipped plugs (with the 100K change interval) are not a good choice in this engine.
3) The plugs cost something like $6 (got NGKs identical to the OEM part at O'Reilly) and the work takes all of 20 minutes if you're going slow. How this is a real problem is beyond me.

It's quick, cheap, and easy to do. I'm not going to climb up in Jeep's rear for specifying plugs with a 30K lifetime. That's a once every two years job for most people, and you can do the air filter while you're in there.

Chrysler used standard copper core plugs in the world engines.

There have been a few threads discussing this.

The plugs cost around a dollar a piece and take less than 15 minutes to change.

I just picked up a set and will be changing them very soon. I only have 23k miles, but I do all city, stop and go, driving.

when i said 30K...i was referring to 30K miles not 30KM. and i have no problem changing spark plugs...but i do find it odd that they suggest 30K spark plug replacement intervals. no sense in arguing since you should follow that schedule to maintain the lifetime powetrain warranty, i just think it's odd

That was all I meant too, it's odd these days to change that early. Yes, years ago with out points etc, changing at 20K or so was not rare, but it is today.

Guess I'll change mine in the spring.

Yeah, I tossed in the conversion for ti-claude, who was commenting about the 50K interval in his manual. I just didn't call it out by a separate quote. Canadian and American units of measurement are going to be different.

As for the 30K interval, it's the nature of the plugs they used. Resister/copper core ones just don't go for 100K miles like the platinums. Those extended life plugs are of more value in vehicles where service is made difficult the engine bay layout, like transverse mount V6 engines where one bank of cylinders is up against the firewall. If you had to swap out plugs every 30K you'd be talking real trouble and money. At 100K miles, you'd do it maybe once or twice during your ownership of the vehicle.

With a DOHC inline 4, the plugs are up on top and easy to reach, so there's really no real benefit to long life plugs. I've often swapped out platinum tipped plugs about every 12-24 months anyway in some cars- they also experience performance degradation over time, just not quite as quickly as more traditional designs. Plugs are an easy item to swap out- if you do your own oil changes, it's only about an extra 10 minutes out there, and you can even do the job while the oil drains.

Brand new to the forums, had a question about the 30,000 mile service. I own a 2008 Jeep Patriot, bought brand new. It came with the lifetime powertrain warranty. Just called to get an oil change at the dealership (which I have done for every oil change since I bought the car) and they mentioned the 30,000 mile service. Quoted $740...yikes. Do I have any other options if I want to keep my lifetime powertrain warranty? How does that warranty work anyway? Doesn't really seem like that great of a warranty at the end of the day if I always have to have the car serviced at the dealership at specific intervals and get a nice wallet pounding on the charges, right?

Im pretty sure the only significant service you need to go to the dealer for is the CVT(trans) service. Other than that, as long as you can prove you have done the oil changes, and changed the spark plugs, they can't void the Powertrain warranty.

Pull out your owners manual to be sure as I can't remember the details exactly.

What I have read in my warranty manual it says you can do the work, but you must keep proof of the work, (i.e. receipts and I suggest a maintenance log to go with the log they give you). (I have a 08 as well with lifetime). For big jobs, I would go to a local mechanic that doesn't change an arm and a leg. (Such as: the 60,000 mile fluid changes).

Dealers usually recommend extra services not included in the manual. All you NEED is the stuff listed in the manual. Although I do some maintenance items myself, I still will take it in for specialized (CVT) maintenance or otherwise troublesome (coolant flush- disposal of antifreeze can be such a pain) work.

They can't void your warranty if you do your own work. As stated, just keep the receipts and write it down in the warranty log book. Disposing oil and anti-freeze is easy. For the oil, I just take it back to Advance Auto or Pep Boys. They take it for free. For the anti-freeze, you just have to hold onto it for a few months. My township has a couple of hazardous waste recycle days a year. Wait for the day, then drive down and dump it for free.

The plugs were too easy, any one could do these. And if you flip the engine cover over and place it on the battery side of the engine bay, it becomes a nice tray to hold everything while you're doing the work. I've noticed a snappier throttle as well.

Dixie, the air filter was definitely tougher then the plugs. It took me like ten minutes to get the darn thing out and back in.

Damn, now I'm a little nervous. Since purchase, I've used the dealership for every oil change, tire rotation, etc. I never had them write anything down in the warranty log. I found the log last night. I know the dealership has a log of every time I've brought my car in there to get a few things done. Should I just get them to sign off on the things they have done up until this point?

if the dealership did the service, then you don't really need to keep a log book. however, it's a good idea to do as a precaution (in case they were to go under).

next time you are at the dealership, ask them to print out a service history for your records. i've done that before and they don't mind
 
#19 ·
Awesome...good advice. I just called them, they had records of everything. Said I could get a print out if necessary. Also, I asked about a recent tune-up they did on the car. Around 28K miles (now we have about 36K) they did an engine tune-up. Included in that was a change in spark plugs. So does that mean I'm good to go on this 30K service because the spark plugs are already taken care of?

others summoned it up pretty well

as for what i have done,
took it to dealer for a couple services/oil changes,
bad experiences with dealers, so wont go back unless i absolutely have to,
have been having my service at local shop, and a subaru dealer(which has a great staff)
i have every receipt, and i log it in the book myself,
as per warranty requirement, do have to follow service schedule, but does not have to be at the dealer, as i recall only dealer requirement is at 5 yr/100k miles where they have to do a diagnostics check.
key to going nondealer and even dealers is keeping receipts for back up.
dont recall 30k service but my recent 60k service was costing $750-$900 at dealers, got it all done for $400 at local shop, (with reciept stating everything that was done), i explained to the shop i want it for warranty records purposes, and he understood and was very detailed on the receipt
