That first startup after changing the oil can do more wear to the engine than an hour trip on the highway. Changing your oil 3 times before you even get to the first real service interval is doing your engine more harm than good. There IS a fine line between going too long between changes and changing too often.
Hey there Sparky..... do tell us how it *does more harm* - and there's no fine line.... it really really depends on how you drive it, where you drive it - temps you drive it in.... and if it's not your money, why in the world would you care?

Why do I care? Because it's EXTREMELY wasteful. That oil ends up getting dumped somewhere...it doesn't just disappear into thin air.

Forum members who have sent their oil to Blackstone Labs for analysis have found that at 5,000 miles the oil is just getting broken in. At 8,000 there is still good protective property left to the oil. At 10,000 some detergents in the oil are still working. Throwing your oil out three times by the time you hit 3,000 miles is like buying a gallon of milk, drinking 3 ounces and throwing the rest in the trash. It's just wasteful.

And yes, there is a fine line. Drain the oil and then the oil pump has to re-prime the pressure upon that first startup. If you're changing your oil every Thursday you're just adding that much wear to your engine. I'm all about taking good care of a vehicle and protecting your investment...but some people are just WAY too anal about oil changes.

What you said makes good sense.

Changing oil at 1000 miles doesn't make sense but if it's one free oil change and $ aren't an issue, case closed/fill boots.

If worried about steel metal particles less than say 20 - 25 microns in size, there are external oil filter magnets and oil pan magnets. Maybe the oil pan should be removed/cleaned with the first oil change to ensure all particles are gone. Some probably go that far.

A first oil change at say 3000 miles sounds reasonable, the oil filter will still have lots of room to trap dirt. Efficiencies of a decent oil filter will be in the 94% to 99% range for particle sizes greater than 20 microns.

Assuming your filter is not a poor quality example, it gets changed to ensure it flows enough oil to your engine that there is not significant quantities of oil blowing straight through the bypass valve.

if your filter is not clogged to such an extent that its flow rate is restricted below acceptable levels, it will continue to perform adequately. Unless your filter is defective or damaged, it will continue to trap sand, metal, and other particles throughout its useful life.

How long your oil lasts is, of course, a function of its quality and your engines duty cycle. If the oil is in good shape and the filter is still flowing enough to do the job, you don't need to change either.

From a wear standpoint, after start up is the worst bit, generally. You're flowing too little, too thick oil around the filter instead of through it. I suppose the folks that change early are concerned about that period just after start up where, perhaps, particles not captured by the filter get an opportunity to flow unhindered though the engine.

From an engineering standpoint, break in is much shorter these days...less important even. After all, we're not talking about an old Soviet tank where they did the first several oil changes only a few hours of run time apart because that took the place of final machining and there was so much debris, so much shaved metal to contend with they had no other choice. Nowadays, we can machine and build an engine to tolerances so tight that the engine and oil must be preheated or the entire thing is seized together and won't even start.

Ultimately, it comes down to knowing enough about your vehicle to make the right choices for that vehicle. If someone gives you a hard rule for every vehicle they are most probably wrong - hard rules may indeed yield adequate results, but they are also frequently a substitute for critical thinking.

I swapped the oil in my bike at a low mileage interval because folks were providing a wealth of data indicating a fair amount of aluminum in the oil - basically, the factory filter and oil weren't getting it done. I often swap the oil in my car at a longer interval - different beast, different requirements. I'm not going to look down my nose at a gent that buys the cheapest oil he can find and changes it every 2000 miles OR the person that follows the recommended interval with some high zoot stuff...point being, make the decision because you think it's the right thing to do after studying the problem.

And shortly afterwards the ECM was programmed to monitor driving conditions, showing when oil should be changed, and most other manufacturers followed.
AMEN!!! Good oil, good filter.....we have 7 vehicles and we use good synthetic oil and change it based on use.

A few of you have hit upon this. It really gets down to how the vehicle is used. Where. What temps. Etc.... I'm not talking about a dd that is used for occasional off road. I'm talking about a jeep, built to travel miles/days at a time off road, through dust/dirt/sand/snow etc.... and the other part of the time dd routine. I put 20k miles on my jeep the first 12 months.... and a lot of that was off road. As I've said before, I work in the back country. My jeep gets *rode hard and put up wet* as the cowboys in my world would say about their horses (in jest).
No rules. No judgement.

You do understand that waste oil can be, and most is, recycled for reuse don't you? Or, are you still dumping yours in a ditch?

Nope, no service contract. Just the first and free oil change.

Meh, bad on them then. End of story. If you want changed, it should have been changed. Either tell them to do it, as it is "1st free oil change", so who cares when your first is besides you or jeep (in this case you). Make them do it, or get it done otherwise. Don't wait and then second guess yourself. If you get a tick, you will always thing back to this moment.

Why not? It came from the ground so doing that is just sending it back home, right?

I can't remember when I had the oil changed for the first time in my Jeep, but I think it was at around 3,000 miles. I can't recall what the manual says but save for that first 3,000 mile oil change, I'm following the recommended schedule in the manual. If something happens, I wanna be able to cover my ass and say, "Look, I followed the recommendations printed in the manual." I am not going to give Chrysler ANY reasons NOT to cover my vehicle if something were to happen.

You guys who are saying people are "throwing away oil" realize that it doesn't get discarded, correct? In fact, more than half the conventional oil on the shelf at the parts store is at least 1/3 recycled oil. Oil is one of VERY few things on this planet that can be re-refined back to its original condition.

Also, "waste oil" is waste- can't be recycled due to chemical contamination of paint thinners, chlorination, etc. "Used oil" is the proper terminology for oil intended for recycling. A capful of chlorinated brake cleaner can contaminate 2,000 gallons of oil beyond recovery.

I change my oil with full synthetic and dealer filter cartridge (since I can't find them aftermarket yet) at ever 5,000 change. I'll be due shortly. I know several people with 200,000 miles and more on their engines, changing the conventional oil ever 5,000 miles. Down here the humidity is outrageous so it's not advised to go too long without changing it no matter what oil you run.

I recall when people on the Internet claimed synthetic auto engine oils were bad because they were too slippery.

Change it when you want. It's your vehicle and your money.

I run straight, conventional oil unless otherwise recommended by the manufacturer or an engine builder. My LT1 in my Camaro lated 17x,000 miles, only to be done in by a head gasket. At that point, I rebuilt it and it now runs synthetic. My 2005 STi ran on conventional 5w30 and did it well until it was totaled with 117,000 miles on the clock. It never ticked, tocked, failed, etc.

I'm not sure what the Jeep uses but if they recommend a particular type of oil, that's going to be what I stick with as well. I'm not going to give Chrysler any more "ammunition" than I need to in case there's a problem with my 3.6L.

I think the Dealer was just trying to save the OP some $ by saying to wait until 3000 miles to change the oil. Who knows, the OE oil may be a higher detergent oil, or somewhat special, so may as well use it for 3000 miles. The oil itself doesn't wear out, the additive package does. The filter is key to collecting/trapping any dirt.

What does one hope to gain by changing the oil at 500 or 1000 miles? Anybody had an oil analysis done with that 1000 mile oil versus 3000 mile oil?

Not here to argue, but this isn't true

BTW, for those that haven't tried it, a [COLOR=blue !important][COLOR=blue !important]Wrangler[/COLOR][/COLOR] has to be the easiest vehicle there is on which to do an oil change.

That oil filter is in a terrible position, IMHO. At least on a JK with 3.8. It is a bitch to get a filter wrench up there if the freakin' dealer over tightened it like mine did.

My 2000 F150 (v6) was the easiest oil change I ever did. Everything was right there, one of the few things any auto engineers did right.

While on the subject, why in the manual does it say "or not more than 6 months". I think that's bs but I do mine spring and fall as that's about 3,000 something miles ..

Sorry to butt in, but my beloved son-in-law owns a JKU, so I think that may qualify me for posting on this thread. I've read most of these posts, and the ones that stick out are you guys that are switching to synthetics. All engines have a break in period, this is when the rings are seating, the valves are finding their way, etc etc. Generally speaking gasoline engines are broke in somewhere between 12 and 24k miles. (Diesels up around the 50k mile mark).... Unless your engine came from the factory with synthetic oil, you should wait for your engine to " break in " before switching to synthetic. If you don't wait, the synthetic oil will prevent your engine from ever "breaking in", which would cause your engine to never reach it's peak efficiency. Let alone, ring blow by, as the rings were never permitted to seat properly. Or. maybe I'm full of it, and this is just old school talk, but I have never had any internal engine problems, and have been using synthetics since they were introduced in the late 70's. And yes,,,, I have always changed oil in a new motor at the 1,000 mile mark. Be good be safe, Have fun

Really depends on vehicle and engine. My wife's CRV uses 0-20 synthetic and they have some special break-in oil they want you to run for first 7000 miles or so. Given Pentastar is using Dino oil, you can change whenever you want and it won't matter, as I understand. Seems like the first change should be between 3 and 6 months, no more than 3k miles though. Leaving the original oil in longer than that would make my anxious, even though it's probably okay. One would think following owners manual would be safe.

Well the reason I change oil early in a new engine is all the various parts are breaking in and metal shavings, all the metal from the honing of cylinders, and everything else that is finding its best clearances is shedding metal into the oil. In my case it is at 500-1000 then usually 3000 after that unless it has a turbo

You don't have an oil filter on your engine?

About the cheapest pos there is. Use good oil filters, like Wix, and let the jeeps ECM decide when it's ready, based on driving conditions, idling, stop and go, etc.

There are so many wrong assumption in this I don't even know where to start. Yeah, filters perform the same day 1 as they do after 4400 miles.

OP, find a new dealer, NOW.

And for every guy that changes their oil at a thousand miles, there's just as many that don't, and so many that change oil every 10,000 miles. The point is, if it makes you feel better doing that, go ahead, that doesn't mean it's the only way. Shavings??? Car manufactures are not going to leave "shavings" in an engine that they warranty for 100,000 miles. one more time, that's the job of the oil filter, which filters the oil BEFORE its pumped to the crank and bearings.

I've never changed my oil at 1,000 miles. EVER. I've always been very religious about changing oil at 3,000-3,500 miles. Subaru recommended oil changes at every 3,700 miles for my STi. I changed the oil every 3,000 miles.

My wife's new 2012 Forester runs on synthetics. I brought the vehicle in at 3,700 miles and the service advisor advised the oil did not need to be changed until the recommended service interval at 7,500 miles. I simply told him I wanted documentation that I was there and was on my way. I had the first service performed at 7,500 miles as he and the owner's manual suggests.

People are saying these manufacturers only want your vehicle to last until the warranty period is up, but that doesn't make sense, especially with Chrysler. Their drivetrain warranty is 100,000 miles. A bumper to bumper is 3yr/36k, or whichever comes first. These days vehicles are lasting a lot longer than 100,000 miles. If Chrysler has a vehicle with a life expectancy of 100,000 miles and GM has one with a life expectancy of 200,000 miles, take a guess which one people are going to buy. It's a no-brainer. Manufacturers want your vehicle to last, because when it lasts, you tell your friends, your friends tell their friends, etc. etc. Case in point is my STi which ran flawlessly until it was totaled at 117,000 miles.

I told EVERYBODY how great that car was, from a reliability aspect AND safety aspect. I've had friends purchase Subarus on my recommendations. In fact, I refuse to NOT have a Subaru parked in my garage. Whether I have a Subaru or my wife does, there WILL be a Subaru parked in my garage. They've earned my business FOR LIFE. We've had ZERO issues with my wife's Forester, as we had ZERO issues with the 2005 STi. Her Forester is climbing towards 8,000 miles and we've owned it for three months. She has a long ride to/from work, hence the high mileage. I am every bit of confident she will see AT LEAST 175,000-200,000 miles out of that vehicle before we consider a new one.

Forum members who have sent their oil to Blackstone Labs for analysis have found that at 5,000 miles the oil is just getting broken in. At 8,000 there is still good protective property left to the oil. At 10,000 some detergents in the oil are still working. Throwing your oil out three times by the time you hit 3,000 miles is like buying a gallon of milk, drinking 3 ounces and throwing the rest in the trash. It's just wasteful.

And yes, there is a fine line. Drain the oil and then the oil pump has to re-prime the pressure upon that first startup. If you're changing your oil every Thursday you're just adding that much wear to your engine. I'm all about taking good care of a vehicle and protecting your investment...but some people are just WAY too anal about oil changes.
It might be just getting broken in at 5k but how dirty is it? And no one said they change their oil every week. They just shortened the interval for the first few oil changes.

All engines have a break in period, this is when the rings are seating, the valves are finding their way, etc etc. Generally speaking gasoline engines are broke in somewhere between 12 and 24k miles. (Diesels up around the 50k mile mark).... Unless your engine came from the factory with synthetic oil, you should wait for your engine to " break in " before switching to synthetic. If you don't wait, the synthetic oil will prevent your engine from ever "breaking in", which would cause your engine to never reach it's peak efficiency. Let alone, ring blow by, as the rings were never permitted to seat properly. Or. maybe I'm full of it, and this is just old school talk, but I have never had any internal engine problems, and have been using synthetics since they were introduced in the late 70's. And yes,,,, I have always changed oil in a new motor at the 1,000 mile mark. Be good be safe, Have fun
careful, you are showing your age. new metals and tighter tolarences have change this. you can add syn in the first 10 miles if you choose to. no ill effects.

My 2000 F150 (v6) was the easiest oil change I ever did. Everything was right there, one of the few things any auto engineers did right.
Sorry, should have said I was talking about a 3.6, where you stand up and remove the filter from a perfectly civil position under the bonnet!
