Exclamation THIS is why you do your first oil change early

Did my first oil change today at just under 1500 miles. I always do the first oil change "early" on cars I buy new and cut open the filters to see what's going on. I found a little more metal than I normally do this round, but also allowed about 500 more miles than normal for a first oil change. I periodically cut open filters on all of my cars and seldom find any shavings after the first oil change.

The way I see this case, it's just evidence that the filter did its job. All engines will shed some metal bits on breaking in as valves seat in and rings wear into cylinder walls. So long as the filter catches the metal shavings, there's little risk that they'll get to journals or bearings and cause harm. I'll run the next change at a normal interval (I change when the meter shows between 15%-25% oil life remaining in cars with such a meter, or when the "change oil soon" light comes on in the car I have without the percentage meter). On the second oil change I'll cut the filter open again. I'll most likely send a sample of that one off for analysis as well.

Originally, I bought Mobil1 and a Fram filter for this oil change. Upon seeing this much metal in the filter, I decided to not take chances with Mobil1, since it technically does NOT meet Chrysler's specification. I went back to Wally World and exchanged it for Royal Purple. I then went to Napa and picked up a Wix filter (which Napa, in turn re-brands as Napa Gold).

Again, I'm not ready to bash my Pentastar motor. Odds are, I'll be perfectly fine. I'm saving the filter, though, and all of my oil change receipts... just in case

Re: THIS is why you do your first oil change early

Not to argue, but I don't see this as proof one must change the oil/filter early on your first change. Looks like there's plenty of surface area left on that stock filter to go longer...just like the Chrysler/Jeep engineers designed it and the 3.6L engine to.

BTW, Mobil 1 is a better oil than the conventional oil that Chrysler/Jeep first puts in (Exxon/Mobil just hasn't paid for the Chrysler certification yet...aka greased their palms), and the use of Fram oil filters is a BIG fail. Mopar oil filters are better & cost like $26 for three on eBay.

Re: THIS is why you do your first oil change early

I've run Fram filters as often as not in my 200,000+ mile Saturn Vue. I won't run a Fram in my Solstice GXP, though... same engine family, but the GXP motor is a little more performance-oriented.

I've read the thing about Mobil1's falling out with Chrysler and that leading to the 2-year certification process, which Mobil decided not to do... I'm a firm believer that M1 is a stellar oil, and I'll never run Penzoil. That being said, I've opted not to put a "non-approved" oil in my engine while it's under warranty.

My point about changing the oil early, though, is that these relatively "big" shavings of metal on the filter to me indicates that there are smaller metal particles floating around in the oil as well. I'd rather drain that out and get as much out of the sump as I can - and get a fresh filter in there as well. Yes, the oil pressure has been fine and continues to be. No, the filter certainly wasn't "clogged" enough to affect that. I'd rather it just not be there any longer than necessary.

It may be overkill, but again I have a 200,000 mile GM engine that hasn't burned a drop of oil. That may have nothing to do with an early oil change and Mobil1 for the life of the motor, but I suspect neither hurts.

Re: THIS is why you do your first oil change early

I'm pretty sure you just proved why you DON'T have to do an oil change early on for your first one... that tiny bit of shavings and you're concerned? I'm surprized there aren't more to be honest with you. Smaller particles then that would never be able to cause any damage internally to the motor.

I'll agree that seeing particles at all is disconcerting but our eyes are not always the good judge we'd like to think. Unless part of a bearing falls out of the pan I rely on analysis at certain intervals. Does it run well, sound good, enjoy it until the next round of recalls. I still cut filters open on occasion

I have to agree.
The filter did it's job, it caught the small particles present in most new engines.

Just because it caught some particles doesn't mean you needed to change the oil and filter.

I have a theory.
People who change their oil too early end up with engines that consume oil.

I've had 3 new V6 engines over the last decade. Each one I waited until the recommended first oil change (well 6000 instead of 8000 on the Jeep because the change oil reminder came on) and I've always switched to full synthetic at the 1st oil change. NONE of those engines have ever consumed oil The Ford had over 50K, the Subaru had around 27K and now the Jeep has 28K. No oil consumption - at all.

Same here...from my old 2004 V8 mach 1 Mustang, 3 Subarus (RS, WRX, STI), 2008 Evo X, 2011 Xterra PRO-4X, to my current 2014 GC Overland V6...none have EVER needed any oil between changes, ever.

Re: THIS is why you do your first oil change early

Of the seven vehicles I've bought new in my 40 years so far, I've always done the first oil change early. I've cumulatively put 500,000 miles on them (with the help of my wife... And this is a conservative estimate). I've drag raced, autocrossed, done track days, and regularly drove on the autobahn in Germany for three years. The point is, my cars don't have easy lives. Nonetheless, I've also never experienced an oil consumption problem. So what?

Let's just agree to disagree, then and move on. I'm sorry my original post offended.

Re: THIS is why you do your first oil change early

My personal experience has linked excessive oil consumption with poor break-in practices. For whatever reason, nearly all manufacturers recommend these ridiculous slow and easy break-ins.

I have always been very aggressive when breaking in, heavy throttle, push RPM's high, and lots of RPM variation and heavy engine breaking (don't break it in on the highway!!!). I have never had a car burn a drop of oil, even cars prone to it, like the Audi 4.2L in both my 2007 S4 and 2012 RS5.

And because I break in aggressively I have always changed oil and filter at 500-1000 miles as a safety precaution (in the grand scheme of things, this is very cheap insurance), and then every 3-6K after that if I'm using synthetic, and depending on how I drive. I consider oil changes very inexpensive given it's literally one of the most critical components to your engine.

YMMV of course.

No offense was ever taken, sorry to upset you.

After all, it's your money to waste.

LOL. Isn't that why we all bought Jeeps in the first place?

Re: THIS is why you do your first oil change early

thread should read this is why you dont need to change your oil early. follow the manufactures specs and you can never go wrong. after all they didnt bring a vehicle into the market without doing extensive research in this area for no reason..t
