Question...

When I take delivery of my '16 Sport, this will be my first Jeep.

Regarding oil changes and the EVIC, Does the sensor actually check the quality of the oil or is it assuming based on driving habits?

I ask because synthetic is going to last longer than conventional, and Conventional Brand X oil is going to have a different TBN than Synthetic Brand Y.

So Conventional Brand X may only last 3,000 miles while (hypothetically) Synthetic Brand Y could last 10,000 miles. Will the sensor actually know the difference?

I will be coming from a Vw TDI which has a 10,000 mile OCI. Being skeptical of 10,000 mile oil changes, I got oil analyses from Blackstone Labs on the first 5 oil changes. They said everything was fine and I could actually inclrease the OCI to 12,500 if I wanted. So I know that oil was good.

Has anyone here ever done an oil analysis after a 3,000 or 5,000 mile oil change?

The sensor doesn't know the difference between synthetic or conventional oil or it's condition. The oil change indicator activates based upon an algorithm programmed into the computer, based upon an owners driving habits which include start/stop cycles, average hours/rpm's, temps, etc., to name a few. Whether synthetic or conventional is used, in order to not have an issue with the powertrain warranty the oil is supposed to be changed at least once a year or 10K miles, whichever comes first, max. This includes whether the oil change indicator activates or not. If an owner prefers not to go by the oil change indicator it can easily be re-set when/if it activates.

Basically what kik said. To give an idea, my Jeep has 30k on it. My oil change light has come on once. Big help :rolleyes:

I change every 5k, put the Jeep up and while it's draining - I do a 5 tire rotation and inspect everything. I also take that opportunity to clean the insides of my wheels :)
Old habit. It has worked, why stop.

We have ours changed 4x per year (every 3 months). Sometimes that's less than 1,200 miles between changes. I seriously doubt we will ever see the oil change light come on unless they forget to reset it a few times in a row at the dealer. :)

I'll explain why if anyone is interested.

Anyway, never exceed 10,000 miles or one year between oil changes, as specified in the owner's manual.

I'll bite... why?
When we bought our Jeep, it included lifetime free oil changes. It's a dealer incentive that I am sure some bean counters calculated that they can use to get people to come back regularly for this free service at which time they try to sell them something that is not needed at an inflated fee. One time, they wrote down a list of over $900 worth of regular maintenance items that they said should be done on our next visit. My wife is the one who usually takes it there and she knows the game. She never agrees to anything they recommend.

If we want to maintain the free oil change program year-after-year we have to take it to them 4x per year, regardless of how few miles it is driven. I think it's silly but it's their rule. Every 3 months I just remind her that it's time.

The sensor does not check the quality of the oil, it bases the interval on engine operating conditions, run time, temperature, etc. I mostly ignore mine and change the oil once a year or at 5K miles which ever comes first. I run a good synthetic oil and I'm positive it is well up to the task. I will be running an analysis at some point, but not just yet because my engine is still too new, less than 5K miles on it and wear metals and silicon will be high.

As it turns out I also own a Liberty and I follow the same oil change interval that I mentioned above. My OLM tripped at about 5,600 miles. That seems to be right.

Once a year or every 10K unless the light comes on. The only problem with that is you won't have as many opportunities to ask questions about what oil or filter to buy, or post about how you have a odd smell sound or vibration after your last oil change. You also miss out on posting threads about fixing something that broke in your filter housing during the last oil change.

Personally, I choose to dump money down the drain by doing it about every 5k when i rotate my tires since I'm lazy.

Change the oil at whatever frequency makes you feel good--as long as you do not exceed the manufacturers recommendation. One thing about oil changes is everyone has their own feel good number. More frequent oil changes then what is recommended by the manufacturer is not going to increase the life of your motor but you will feel better about it.

while this doesn't apply to our Jeeps...for those with vehicles with newer engines with low tension piston rings, if you wait until 6,000 or 7,500 or 10,000 miles between changes i sure hope you check your oil levels frequently.

these newer engines with the low tension piston rings are notoriously known for consuming oil. google all of the class action suits against Nissan, Honda, Subaru, and others. the manufacturer fix was to re-design the low tension piston rings...but they are still low tension and are ticking time bombs for consumption. with low tension piston rings, it's not a matter of if but when they start consuming. all those manufacturers did, was delay the inevitable so the consumption will occur later on and they're hoping outside of the warranty.

so if you're not already doing this...check your oil level at a minimum once a month and depending on how many miles you do, every other fill-up

lol ya
I had a 15 subaru as a winter car that i traded in on this jeep. People on the subaru forums where flipping their shit over the oil usage. MAYBE it might use .5-1qrt in 5K miles and people where demanding their engines pulled and rebuilt. Imagine having a new car then having who-knows-who at the dealership completely disassemble and rebuild the engine over 1/2 qrt of oil. 0w20+boxer engine. Ya its gona use some oil.

I made a service appointment for Nov. By that time I should have 4,000 miles on it. Will do it at the dealer who sold me the Jeep, Koons at Tysons Corer in VA -- but it will definitely be the first and last time: I called Koons to ask how much the first service would roughly cost me. All I ask for was an estimate. I talked (or better: waited!) 45 minutes on the phone and talked to 12 different people at Koons, but nobody could tell me how much it will be. A few hours later I get a voice mail that I should call back because they have figured it out. But the voicemail doesn't give me the estimate either. So I called and talked to 5 different people again (none of them could help me) until I finally give up. They said they will tell me when I drop the Jeep off.

Koons at Tysons Corner in VA SUCKS!

Every 5K for me and a five tire rotation as well.
