Oil Change??

On the manual it says oil changed should be done every 10,000km, but I've only put a bit more than 4,000km on my new JK and the light comes on to remind me for an oil change already... Should I do it now or wait until about 10,000km?? why does the light come on so early?

Another question is, is there any difference in changing oil at places like the dealership, Jiffy Lube, or a private garage? either the cost or sth else?

thanks

IMO oil change intervals are highly dependant upon driving conditions.

A car that sees only road use and running standard oils, I'll stretch it out beyond the 3mo/3k. When the oil appears to be nearing the end of it's life; indicated by darkening color, slightly burnt odor, noticably increased valve train noise on cold start, etc, etc, I'll go ahead and change it. I have known some hardcore gearheads that have their oil analysed for heavy metals and viscosity breakdown to determine the exact state of the oil and establish oil change intevals with that data in mind.

Previous Jeeps that see fairly regular off road use, I always stick to the lower end of the range and at times have changed it well before the 3 month/3000 miles if it looked like it needed it.

Now, for my 08 JK with computerized this, that, hell~ damn near everything, I have decided to let the ECU tell me when it needs to be changed for two reasons:

1. I like the idea of my drivetrain warranty and seein g as this IS a Chrysler product I will make every attempt to keep it valid for at least the first 100K miles. I am also fairly confident that any attempted warranty claims down the road are going to be subject to an audit of my maintenance records. For this reason alone, I take my Jeep to the same dealer I purchased it from for all my maintenance and, so far, most repairs. Just within the past 6 months, this has already established a positive business relationship and I get many "percs" so to speak. $11 tire rotations, $14 oil changes, reductions in labor charges, etc. I've even been thrown several deals on accessories, parts, take offs etc. I also have the (relative) peace of mind knowing that in the event something is done improperly and results in damage/breakage, I stand on firmer ground than with the prospect of dealing with JiffyLubes corporate lawyers.

2. All this computerized garbage... I love old motors, give me a carburated sb anyday, so much easier to work with... That said, I have also noticed that the ECU reports oil change requirements much sooner than the recommended intervals as specified in the maintenance schedule but I attributed mine to the fact that my Jeep sees regular (twice a month, sometimes more) duty in dusty, dirty conditions and my dealer knows it. I have taken my Jeep in several times mudy, grass hanging off the frame, etc and they have no issue with it. They just say "you use it to do what it was made to do". I don't want it to come down to "your change oil light came on 1000 miles and/or 2 months ago and you're here NOW? Well, you have a bad/worn (insert engine component here) and it's on your dime, oh and BTW your engine warranty is now void.

All that aside, (and I'm no lawyer) if you stick to the printed, published maintenance schedule for your Jeep and keep good records (all receipts, dates, mileage, noted of service performed, etc) it shouldn't matter where you get your maintenance done, even if it's your own driveway.

Now the above will keep your warranty happy. If you're primary concern is longevity of your engine, check your oil often and change it when it looks like needs it. Synthetic oils typically last longer than conventional ones do and that has much to do with the doubling of oil change intervals in most newer vehicles maintenance schedules. If you are running conventional oil, stick close to the 3mo/3k schedule.

Realized I didn't answer your primary question:

At 4,000 miles on a new motor, I would change it now regardless of what you decide to go with for a oil change interval down the road. Engine break-in does result in heavy metal deposits in the oil and IMO should be changed around 3k.

4000 kilometers is only 2500 miles.. I think the stock setting on most Wranglers if for the first oil change at 3000 miles and the light comes on a bit before that, mine came on the first time at 2500 miles.. I'd go ahead and change at 4000 kilos the first time then 10,000 kilos after that.. the big difference between the dealer and Jiffy lube is the guys at Jiffy lube will not know how to reset the light!!! Look through the owners manual, the instructions are on page 207 in the 08 manual.

Mine came on @2500 miles the first time too, had the dealer change the oil and reset it. Now have 5227 and the light hasn't come on again yet and probably won't until it gets to 6500 - 7500 miles on it.

I have a question?

I have an 07 X 2dr and I have never seen the light come on. Do they all have the light? I change mine every 3500 miles, should I wait and see if a light comes on?

3500 should be good, all the 07-09's have the oil change light but there's no need to 'wait' for it. Be sure to do a reset after each change to keep it accurate.

I have 23,000 mile and the dealership changed it once and I changed it the rest but the light has never come on. That is why I thought my X did not have a light. IF the oil is go will the light still come on after some many miles or does it just come on when it is broken down( oil that is)?

Update:

I had the dealership change the oil for me last weekend and I was told if you do a lot of city driving, then you will need to change oil more often. Plus, the first time the indicator comes on earlier than later

It is by miles and or a combination of miles and how the engine has been run (high RPM, low RPM and such) In other words, it should come on occasionally no matter how often you change the oil.

Although if mine was broke, it is not something I would bother fixing.

Oil Change

My understanding is that the factory has a set point to change the oil and they are all different. Mine came on at 2500 and the dealership asked me when it came on (I took it in at 2700 miles).They asked me if I would like to have it warn me at 3000 miles. They made a comment about every jeep is different. I have always changed it at 3000 miles regardless. except this time I wanted the dealership to make some other changes so I took it in early. I hope that makes sense.

Absolute BS!!!!! Since the upgrades in oil technology back in the 70s, no engine made needs to be changed at 3000 miles!!!!

Remember this is a sue happy country and no manufacturer would even consider letting you go close to as long as might be reasonable, and yet the Wrangler manual says under normal conditions 6000 miles!!!!!!! And that is with normal dino oil. Many dealers since have come up with setting the computer to alert ever 3000 to make more money and are using the lifetime warranty as an excuse. The fact is if you change ever 6000 (even if you do it yourself and keep the receipts) they cannot void the warranty!!!

Get a clue.

It simply amazes me how many car owners stick with the antiquated 3,000 mile change interval in direct contradiction of owner's manuals and advances in modern technology in oils, unleaded fuels, improved emissions, etc.

Trust the engineers that designed your vehicle. They know a heck lot more than the goofballs at the local quick-change-and-lube-rip-off-joint who want you to believe in yester-year's technology and old wive's tales.

What is truly ironic is that more than half the people that stick with the 3k oil change weren't even born yet back when it was actually necessary!!

Good observation! My dad died at age 90 ....... 10 years ago ... I can forgive him for such outdated ideas. Afterall, when he died he had a 1969 Chrysler Newport that he bought new and he is forgiven for out-of-date ideas (God rest his soul) ........... but, Holy Moses, not in the 21st century, for heaven's sake.

Can anyone of the 3K Club give any substantive evidence of the necessity or benefits of such primitave and pre-historic practices? C'mon, just one? .................................................. ....................

Does it have anything to do with longevity of the engine or the MPG? i mean, if you change oil every 3k miles rather than 6k miles?

I usually change it between 3 and 4K. I wait till it gets dirty, just before it goes black. I just don't like the idea of lubricating with dirt particles in the oil. It reminds me of why when the outside gets muddy we just don't wipe it off, cause it scratches the paint finish. Call me old fashioned but it works for me.

Just because the oil has gotten darker it does not mean it has dirt in it or has lost its lubricating properties. And if it actually has dirt in it at 3K, you need a better oil filter.
