Brought mine into my dealer at 5k and they told me I didn't have to get it done until I was nearing 10k. I had them make note of it, they said the new vehicles coming out running full synthetic can go 10k and be fine between changes.

Yikes! This is why I look for other inputs because in the manual I just read this "NOTE: Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km) or one year, whichever comes first.

Severe Duty All Models
Change Engine Oil at 4,000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment"

I would never wait that late to get an oil change, around, near or passed 10k. I do not live in a dusty or dirty area either so 4k is too soon.

They have an internal sensor that should tell you when depending on conditions and how you drive - I was starting to get worried but just got my prompt at 6900 miles.

It may be possible to safely exceed even 10k mil OCIs. UOA showed my Audi's oil to still have 30% more miles under the same conditions left at 12k miles.

There is a lot more to oil "wearing out" than contamination by particulates. Dusty conditions are just one factor contributing to oil becoming unsuitable.

One can measure the TBN (Total Base Number), which indicates the reserve alkalinity remaining in the oil, which is necessary to neutralize the acidic byproducts of combustion. At some point the oil's acid neutralizing capacity is exhausted. TAN (Total Acid Number) measures oil oxidation and build-up of acidic compounds.

Oil also may thicken over time due to contamination. This can result in sludge and impeded lubrication and increased/abnormal wear.

Oil can also shear (get thinner) over time due to mechanically getting "beat up" (cams, timing chains, valve train), and the resulting thinner oil viscosity may cause wear under high stress conditions (for example, high oil temperature).

Oil also can thin due too fuel dilution (fuel gets into the oil due to incomplete combustion)

Moisture can accumulate in the oil (engine does not get fully warmed up/driven only short distances). This can also cause sludge buildup.

Anti-wear additives in the oil get over time depleted.

A modern car's OLM gives a good indication regarding oil life and is a good starting point. An occasional UOA will allow maximizing oil change intervals safely.

oil change

Currently my latitude is at 7603 miles. I went by the service department I told them about how many miles I had on my jeep. I told them I am a member of the renegade forum. That my jeep still has not said anything about a service being due. He told me to bring it in and they will take care of it. He also said I need to have my tires rotated and that can be done as well. I said thanks and will get that taken care of soon. Then tonight while I am driving I get a service engine soon light. This occurred at 7602 miles. What a coincidence I speak to the dealer about service and the jeep's service light comes on.

 

[Husky777]

Mandatory service is 10k miles. 7-8 is a fairly accurate average for an oil change interval. It doesn't sound like they changed it, however. Is it a service vehicle or oil condition warning?

 

[flash75]

My oil change light came on at around 7615 miles. I may not have noticed it when it first came on. The message
comes on for a few seconds each time the engine is started. Had oil changed at 7619 miles. They placed their
service reminder sticker on the windshield, next service due 8/16, 13,621 miles. Of course that's only 5 k miles
or six months. They are totally ignoring the built in oil change indicator as listed and shown in the manual.

My light came on at about 7500 miles. I've been going for oil changes at 6000 to 7000 mile intervals. I'm at 18,000 miles, rotation of tires at every other oil change. I'm now averaging 1000 miles a week with my TH. I've been using the Ultra and signed up for the 300,000 mile warranty from Pennzoil.

You didn't correct that it's 6k miles. 13k-7k=6k. >

I know myself as well as others start getting a bit paranoid waiting for the vehicle to indicate the first oil change is needed.

Just wondering what mileage you got yours at. Mine finally went off at 6305.

7025 miles

OK, everyone, the change oil indicator is just a algorithm based on several factors, like idle time and speed over length of time. They do not analysis the actual oil. Turbos are very hot and cooled by oil, so in this case on the 1.4L I would do 10k unless I had UOA to back it up. Mine is the 2.4 and spin on filter so 20k is no prob at all!

Yes you do want to change the oil in the first 1-2k due to break in and more so filter change! Engines are not broken in over 50 miles or 2 hours run time. Ring float can be a big factor if not seated well.

I did my first at 1k then 10k and then on at 20k per change. Yes use JustSynthetic and change 1 year or 10k unless your reminder goes off first or like me you have a by-pass filter and use 0w-20 good for 25k Miles. just my 2 cents!

The only time over 10k miles is if you have a Full synthetic media filter like a Amsoil Eao, not a paper like mopar or fram!

Consumer report did a study of synthetic oil in NY taxi cab about 10 years ago. At NO POINT was the oil they tested below acceptable spec for usage after 10 or even 15 thousand miles. In fact, many synthetic oil brand measured as well as new after 10 g miles.
Anyway, I agree I would not exceed 10g in my car and will just change when it says to...

Engine Oil Change

Im currently at 7600 miles, but for some reason the "Engine Oil Change" warning randomly popped up on my dash screen and disappeared. Is that normal? I know the first oil change service is at 10,000 miles according to the manual. Could it be just a heads up?

 

[JONPASCUAL]

Disregard. Just found out my answer. Didn't know there are threads that are already made thats related to this issue.

 

[flash75]

Actually the oil should be changed when that light comes on. Read the quote below from the Renegade
owners manual, it's on page 522.

Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further information.
NOTE: Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km) or twelve
months, whichever occurs first

I don't wait for a computer light message to tell me to when to change my oil. Every 5K miles plus on the odometer, it's getting changed.

 

[Julian Osborne]

Never had an oil warning on my 1.6 Diesel Limited - but today I did... and it keeps reminding me!

First service was 12,000 miles, so oil was changed then, but the "Engine Oil Degraded" caption only came on at 21,697 miles... booked in for 2nd Service on Monday!

I have had the Jeep for 6 days under a year, so managed a good range of driving in that time... for a Brit ��

 

[randyr5]

My "Oil Change Required" message just came on at 5900 miles (2.4L). Used Pennzoil Platinum 0W-20 and a Wix 57060 filter.
Reset oil counter per instructions found elsewhere on this forum.
All good.

I am old school with oil changes and start to get itchy when I pass the 3000k mile mark with the oil in the vehicle.
I know most vehicles now with full synthetic oils can go 5-10k between changes (my wife's civic INSISTS on waiting until 10k to notify her), but it still bothers me. I find 5-6k between oil changes with a turbo charged engine is happy medium for me (took me a while to get to that point). Not so frequent that I am hurting my wallet, but not so infrequent that I start to get worried.
