i would do it 1000 first oil change is most important

 

I have oil OCD. I always change the oil in my new vehicles before 1,000 miles and every 3,000 after that. Yes, I use top shelf full synthetic oil but I still change the oil. I think this is a generational issue. If you grew up like I did in the late 60s and 70s you saw people lose engines from neglect. My sister burned up our precious 68 VW Bug. My dad was known for his saying about oil. "You are forbidden to drive the car without oil but you are welcome to drive it without gas". If he ever caught us with the oil low we would lose driving privileges for weeks. So, how did my sister do it? She took the Bug to college where dad was not able to check on her.

I guess you can tell it still bothers me to this day.

Change the oil when you want to and ignore all the rest of us. Just make sure to get it done within intervals to protect your Jeep warranty.

 

Personal preference in my opinion. I usually go the full duration with all my new vehicles unless i will taking it on a long vacation after purchase and dont want to mess with it during the trip if i will over-drive the oil change.

 

I was always under the impression that the first oil change needed to be completed around 1,000 miles and that you should follow a prescribed method for breaking in a new engine to ensure that the piston rings seated and sealed properly.

After doing some reading recently, it seems that current manufacturing processes result in a much smoother cylinder wall finish. The smoother cylinder wall surface reduces the break-in period to the first several miles of driving as opposed to the first several hundred miles and minimizes the amount of metal shavings and combustion contaminants that pollute the motor oil during engine break-in. Due to this reduction, a normal oil change interval is sufficient for the first oil change. There is also some information that suggests that modern oil filters are more efficient and better capture and hold any break-in metal particles than the oil filters of yesteryear. I will say that when I checked my wife’s Toyota Highlander oil after the first 5k miles, it still looked like brand new oil.

Ultimately, no harm can be done by changing the oil too soon. If it gives you peace of mind to conduct a “break-in oil change” prior to the recommended oil change interval, the worst thing you have done is spent some money that was not necessary.

That's a hot topic on other sites, often ending in a flame war or a locked thread. Hopefully it doesn't end the same way here. If it were mine the oil would be changed within the first 1,000 miles. I'd probably leave the filter alone. If you look at used oil analysis on new engines you'll see a lot of wear metal in the oil, even with newer improved engine manufacturing techniques. I for one want that junk out sooner rather than later. The flip side of the argument is there are millions of engines that don't get the oil swapped out early and run fine for their entire life. Bottom line do what you decide is best.

 

When I bought my Tacoma in 2007 I asked the service manager the same question as the OP asked. He said there's no need to do that anymore. He told me to change the oil as recommended in the manual and that's what I have done. I change the oil and filter each 5K miles and it now has 218K miles on it. Still doesn't use any oil between changes.

When I took delivery of my 2021 Willys I asked the service manager the same question and got the same answer as with the Tacoma.

But if it removes any stress from your life then change it at 1K and don't look back. Good luck.

 

I believe in an early oil change. The oil and engine quality have definitely improved over the years. However, you still have break in contamination. I keep my vehicles a long time and my first oil change is at around 1,000 miles.

 

I do the first oil change at 1,000 miles, then at 5,000 miles and then every 5,000 miles after that, along with a 5-tire rotation every 5,000 miles.

 

First oil change 1,000 miles. 3,000 to 5,000 thereafter.

Follow your Owners Manual for engine break-in recommendations concerning oil changes, driving, and towing.

EDIT: I was going to add this earlier.

I bet 90% of new Jeep owners do not follow what is in orange below. I didn't.

ENGINE BREAK-IN RECOMMENDATIONS A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle. Drive moderately during the first 300 miles (500 km). After the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable. While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. Wide-open throttle acceleration in low gear can be detrimental and should be avoided. The engine oil installed in the engine at the factory is a high-quality energy conserving type lubricant. Oil changes should be consistent with anticipated climate conditions under which vehicle operations will occur. Refer to “Maintenance Procedures” in “Maintaining Your Vehicle” for the recommended viscosity and quality grades

Towing Requirements To promote proper break-in of your new vehicle drivetrain components, the following guidelines are recommended: NOTE: Trailer towing requires special rear axle lubricant. Refer to “Fluids, Lubricants, And Genuine Parts” in “Maintaining Your Vehicle” for the correct fluid type.

CAUTION!
• Do not tow a trailer at all during the first 500 miles (805 km) the new vehicle is driven. The engine, axle or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a trailer is towed, do not drive over 50 mph (80 km/h) and do not make starts at full throttle. This helps the engine and other parts of the vehicle wear in at the heavier loads.

NOTE: A new engine may consume some oil during its first few thousand miles (kilometers) of operation. This should be considered a normal part of the break-in and not interpreted as an indication of difficulty

MAINTENANCE SCHEDULE Your vehicle is equipped with an automatic oil change indicator system. The oil change indicator system will remind you that it is time to take your vehicle in for scheduled maintenance. Based on engine operation conditions, the oil change indicator message will illuminate. This means that service is required for your vehicle. Operating conditions such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures will influence when the “Change Oil” or “Oil Change Required” message is displayed. Severe Operating Conditions can cause the change oil message to illuminate as early as 3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as possible, within the next 500 miles (805 km).

NOTE: Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km), twelve months or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers. 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, or is operated predominately at idle or only very low engine RPM’s. This type of vehicle use is considered Severe Duty

 

So, here is my take.
Changing the oil at the first 1000 miles is not a bad thing and can’t hurt at all BUT one shouldn’t start using full synthetic oil until at least 6,000miles.
Synthetic oil reduces friction and in old school thinking hinders the proper initial break in. After the first 6000mi (10,000 klm) then I will switch too Amsoil. I still follow a strict driving, break in protocol as I always have, no matter what the manufacturers say (remember they don’t make money off high mileage vehicles). I’ve be been doing this process for 40years and have always got high mileage from my engines.
Again my old school opinion.

I agree with your comments and prefer to break my engines in with a petroleum oil. The problem is the JL 3.6's use 0w20, which I have not seen in a non-synthetic oil.

 

It is always interesting to see the different approach to break in. I can say whatever and it is just my opinion, because how many people have come in here and posted… “I didn’t change my oil until x miles during break in and now it is dead at xx miles!” Also the thing about switching to synthetic at x miles. Same thing. Who knows? All I can say is changing your oil doesn’t hurt it, unless you do it wrong…. Changing to synthetic doesn’t hurt it. They are just oil. They provide lubrication.

Break in procedure… all I can say is I bought a brand new truck in 2000. while I was doing paper work for my new truck, they issued a evacuation notice for my home. So with under 100 miles on the truck I hooked up to the horse trailer and pulled loads of horses out of the mountains. I still have that truck and it only has 350k miles on it with the original clutch and engine In it.

What I don’t understand is that it is very well know and followed everywhere that a new differential needs to be changed after 500 miles. Why don’t people ask about whether to change diff fluid? Seems like everyone is focused on engine oil?

Good observation. Even though auto manufactures as a whole do not recommend early engine oil or differential fluid changes, where does the 500 mile differential fluid change come from? Simple answer. It comes from aftermarket rebuilds.

If you rebuild the rear end or rebuild an engine an early oil change is a common recommendation. And while I wouldn't pull the oil pan off a rebuilt engine at 500 miles to change the oil and visually inspect internals, I might remove the differential cover at 500 miles to verify gear teeth are not damaged or show premature mesh problems. What distinguishes difference between the fluid replacement intervals in a new vs rebuild wigget is simple.

New engines and differentials (among other parts) are assembled in production facilities that are subject to ISO and IATF automotive standards and auditing for quality adherence. Tools and test equipment is calibrated and there is also periodic sampling of production LOTs. Over time using production and historical data manufacturers are able to establish maintenance intervals that allow extended maintenance schedules. Break-in doesn't mean the engine, differential, transfer case, or transmission needs early servicing.

Whereas the typical private owner and private repair shop does not undergo periodic quality audits, and every job they perform is really a one-off so they aren't going to audit and record anything they rebuild let alone repair. So, an early fluid change makes a lot of sense IMHO when it involves a rebuild so you can detect an early failure in the making.

 

^^Well said

 

Oddly the pre-PUG 3.6L motor factory fill was petroleum based oil... the PUG factory fill is supposed to be synthetic... at least that's what the dealer tells me. So whatever the factory fill is, the oil gets changed-out at the first 500 miles and then progressive changes like @Old Dogger stated.

SRT's with Hemi motors come with synthetic from the factory, therefore the same priciples apply.

 

I have a 392 Charger and never heard from any dealer or read in the owners manual any recommendation to follow a stepped oil servicing schedule. It uses MS-12633 0w-40 and until last year only Pennzoil met that spec and the oil retailed for about $11-12 a quart. Ive seen it go for upward of $15 a quart. 7 quart system. It isnt available in gallon jugs or drum and is not always easy to source. The Charger 392 has a 6000 mile/6 month oil change interval and usually no one was eager to change oil at 6 months if they only drove 3,000 miles.

However, like this thread there were advocates for an early oil change for the SRT but the SRT discussion center mostly about the benefits and risks of using oil not certified to MS-12633 like Mobile 1 and extending oil change beyond 6 months.

The progressive oil changes is a personal preference.

Purchase oil on Amazon and you'll get better prices... approx $7 per quart and it gets delivered on your doorstep.

 

Concur on preference but that position isn't always presented that way and can be misconstrued as authoritive.

The SRT oil also comes packaged as a kit of 7 quarts + filter. I usually buy 3 oil change kits at a time. Prices went down soon after Valvoline was MS certified.

 

Hi! I was told the same but the JL sensors are so high tech. My Jeep notified me at 6,500 miles. On the dash it will say Oil change soon. So I depend on the car to tell me, not when the dealer does. If you ignore the notification it will then say Oil change needed. Hope this helps! Happy New Years!

 

You can go the full normal change duration. Changes at the 500-1000 mile mark was based on the time when breakin oil was used and no longer the case.

Well, not really. I'm too young to remember when they used break-in oil...

I do it based on reports like this below metal shavings were left behind due to poor cleaning of the aluminum block during the machining process. These real scenarios left the perception that Hemis, Pentastars, etc. can leave the factories contaminated...

Aside from this fiasco in Mexico, I've always flushed the engine at certain points to mitigate potential wear cause by metal shavings from manufacturing processes or first 500 run-in miles.

Again, it's a personal preference...

 

First 1,000 miles then 3,000 to 3,500 after that is what I do on all new cars. If I buy I used one I change immediately.

 

A lot of people waaay more knowledgeable than me have put a great deal of time and effort in refining modern oil both Dino and synthetic, creating modern oil filters, algorithms and sensors to evaluate oil condition. When the car tells me it’s time to change the oil I do. A huge amount of perfectly good oil gets sent off to the recycle sites, or dumped somewhere. So unless you operate your vehicle under harsh conditions as discussed in the manual, to quote Biden “listen to the science(car)”.

 

We are all better off to not listen to him lol

if you are running synthetic, the oil doesn't break down like petro based oil, it simply gets loaded up with dirt, and garbage. I know people are always about pushing oil changes but honestly getting a rigorous filter change schedule is as or imo more important, unless you have coolant leaking into your oil.

 

same as others 1,000 and 3,000

 

as long as you go by the manufactures recomendations, I would not worry,

 

Looks like you’ve received lots of replies already, but I’ll add my two cents…. I changed my oil at 500 miles and then I’ll stick with the recommended oil change interval (for me it’s once a year as I don’t drive it often). Always full synthetic.

On my 150,000 mile Yukon I’ve been doing 10,000 mile changes (per manufacture spec) or 1 year (whichever comes first) and she’s running great!

 

I changed mine @ 14,242k ...probably the 2nd oil change...1 from the previous owner.
Had it tested...analysis said it still showed lingering break-in material on the 2nd oil fill that they believed had 7,000 miles on it.
Had I bought it new I would have likely changed it @ 800-1000 to Amsoil, then @ 3,000 then every 5k-7k thereafter. That is how I handled my 2004 TJ when I bought it new. Although I am pretty sure I changed the oil every 5k on it.

Someone had reset the oil change indicator to 100% when I took possession of it which was not true.

 

I have a new 2021 Rubicon 3.6 auto. My salesman ( who has a JL ) recommended 5,000. With the JEEP wave, I think the first three are free.
