First oil change

Hi everyone. my '12 GCO just hit 5,000 miles. The service manager told me to wait until I get an EVIC message to schedule the oil change. What's your opinion on this? I trust him, but wanted to ensure I should continue trusting him

The oil change message on the EVIC can be changed. Check the service schedule that came with the jeep. Then read your manual on how to change your EVIC oil change interval. I'm pretty sure you are correct but I've got an 08' Diesel GC and it's every 10,000.

The manual says service at 8,500 miles (V6). I had my first oil changed at 5k.

On the wk2 i do not believe the interval is changeable. I think you will be just fine waiting for the evic. Just make sure you dont go over the the 8,000 mile mark.

That brings up a good point. What happens if we change the oil ourselves. How do we reset the EVIC so it'll know we changed the oil? I don't remember seeing anything that dealt with that.

From the FAQ thread at the top of this forum...
http://www.jeepforum.com/forum/f309/...ation-1173618/

Similar info in your owners manual too.

Oil Changes

The WK2 has an oil change indicator system. This system displays a “Oil Change Required” or “Oil Change” message at appropriate intervals on the instrument cluster. The Oil Change Indicator system uses the Powertrain Control Module to process a variety of inputs and then decides on an oil change interval. The factors which point toward severe use include the following:

* Ambient temperature inputs which indicate extended periods of low temperature operation
* Average vehicle speeds which indicate stop-and-go driving
* Run time which indicates prolonged idling
* Trip lengths and coolant temperatures which indicate short trips
* Engine RPM and engine loads which indicate trailer tow usage
* Fuel indications of an ethanol percentage of 60 percent or greater

The oil change indicator can be reset using the following steps:

1. Turn the ignition key to ON but do not start the engine. If you have the push button start, press the button twice with the key in the vehicle and your foot OFF the brake.
2. Slowly depress the accelerator to the floor and release it three times within 10 seconds.
3. Turn the ignition key to the OFF position (or press the push button to turn OFF).

Thank you for that. I was waiting to read that we had to jump through a few more hoops in order to reset it. I'm sure that's a quick and easy way to do it in practice, but just reading it sounds much more involved than just pressing a reset button a display.

For a brand new vehicle, I typically like to do one around 1500 -- sometimes even less if the vehicle has sat on the lot long enough. Remember, there is also a time interval requirement. EVIC, 6 months, 8500 miles -- whichever comes first. I plan to change mine this weekend (around 1700 mi), and then take advantage of the 2 free dealer OCIs afterwards.

When I bought my car (MKZ), the oil change light came on during the test drive. It was sort of a "demo", but only had 700 mi. However, those 700 mi were all very short trips, and it was on the lot for ~ 1 year (owner drove it). Thus, I changed the oil the weekend I brought it home.

so you really should change the oil at 8500 (or whatever your JGC requires) OR 6 months? i only drive 8000 miles a year so i've been pretty much doing it yearly on my other car, but i'll start doing it every six months on the new jeep.

I special ordered my JGC. I changed mine to Mobil 1 blend at 500 miles. I don't trust break-in oil. I am coming up on 5k. I will put Mobil 1 fully synthetic in it at that time. 5k should be enough to seat the rings and lubricate the seals. If it's not, the 100k warranty can take care of that.

I like to visually check the oil....I actually check the level and color on the dipstick. If its getting too dirty before the oil is due then I change it. I guess that is old school though.

My Jeep dealer here in Denver said that at high altitude you want to do it every 5,000 miles instead of every 8,000 or whatever it says in the manual. I think I'd do every 5,000 anyway to keep it running best.

A mechanic I trust once told me that it is best not to follow the recommended oil change mileage when you get more miles on a car. Car makers want their engines to start to break down after 100K miles so you go and buy a new one, but still feel like your car lasted a while so you don't dump the brand.

The manual says every 8000 miles, but I was also talked into buying scheduled maintenance care. It says 3 months or 4,000 miles. It's basically the same schedule but they added an extra oil change in between all the scheduled services in the book. You better believe I'm taking my Jeep in for an oil change every 3 months! lol. I only drive about 9000 miles a year.

You should change your oil at or close to the recommended mileage based on light duty driving. If you have severe driving, such as towing then it should be done sooner. I wouldn't go over 5000 miles under these conditions, although the EVIC will most likely alert you. The time is also important. Never go over 6 months, reguardless of the mileage. The reason is that you oil becomes acidic with time and can actually eat bearing surfaces with micro pitting. Just looking at your oil is useless. You can't tell by looking at the level of black in the oil. The best way is to have an oil sample sent out for testing and that will tell you what condition the oil is in at that mileage/time interval. Most people don't bother with this due to cost and time. Thats why they came up with the mileage/time schedule because it covers most drivers.
