I understand where you're coming from but the words would not be mine and I would always desire to differ to an expert when providing information meant to be shared on a forum. I'm not a Tribologist like the guy in the video is. He is a lubrication / oil expert, for which I differed to in order to explain why Auto Manufacturers are not handling their new vehicles engines with a typical break in process as they use to. I trust his professional opinion, as it is clearly based on scientific facts that are pertinent to his profession. I wouldn't expect anyone on this forum to trust my opinion, while I have years of experience with autos, am a mechanical engineer, worked over 30 years in manufacturing facilities, 27 of which were with OE Auto Parts Manufacturers, I'm not an expert in certain areas as this gentleman clearly is.

 

Mid, the advantage of placing a "larger" surface area magnet such as a FilterMag (which infers magnetic partlcles) is that if its placed on the surface of the oil filter those particles traveling within the oil will (theoretically) be captured by the magnet and not be trapped within the filter, leaving a larger free surface area of the oil filter to pull out "non ferrous/magnetic particles. A oil pan drain bolt that has a small magnetic surface. 100% of the oil must pass thru the oil filter.
The video is worth a watch for those that take the time to watch it. It convinced me to do two oil changes prior to the Lexus 10k mile change.

 

Okay, I listen to the 9 minute video dribble. For one thing science and data are not based on one case Wow.
(1) more people lease cars so they don't do maintenance, so car manufacturers don't use break-in oil anymore.
(2) they use a lower viscosity oil to better mpg to meet CAFE standards.

Okay there are some higher metal parts at first change. Here is the study that is needed : compare valid statistical set of cars , let's say 100. One set the first oil change is not until 10,000 miles. The second set the first change is a 1,000 miles. Then look at how long the cars last without problems. If the first set with the change at 10,000 only go 90,000 miles and the second set go 150,000 then that is significant difference. However, this long-term testing if it has been done is not documented. So what do we really know? not much. We speculate that the 1,000 mile initial oil change will improve the longevity of the engine but how much ?

In his one test, it did show initial copper, aluminum and iron filings. As mentioned earlier a magnet can get the ferrous metal out , but in this case the aluminum filings were much higher. A magnet will not attract Aluminum filings nor copper.

Okay to be safe , yes change you oil at 1,000 miles ( this my be overkill , but how much overkill ....maybe iti s necessary for over 200,000 mile longevity or even 100,000mile longevity.

Synthetic oil has a cycle of 10,000 miles. But probably the best longevity and conservative is to change oil and filter. every 5,000 miles ( first at 5,000 also) . One thing to remember, is when you change the oil , you don't completely change it; there is still oil residue withing the engine, not all oil is drained out , only most of it.

So I am still not convinced on how much good the first change at 1,000 miles does. Some good for sure , but how much.

Now I need to find out how to get the 9 minutes and 30 seconds back that I wasted watching the video

 

It would appear more time was wasted on scripting a post rather than educating oneself from one of several experts. Rather than challenge the concept of metal particles in break in oil on this thread , spend your time googleing the topic to learn that this fact is what others have found. In a number of cases in Toyota's, metal particles are extracted or caught in filters ... so, please google the topic rather than stiring up and challenging those more knowledgeable on the the topic here.....

 

@Lexicon1 great advice as usual. "scripting" and "googling" great advice as usual. Please explain what you mean by "more knowledgeable" .I am always willing to learn from the "experts"

P.S. - There is no longer "break-in" oil

Mid
If one follows your great posts as we all do, you do an extensive amount of copy and paste from other sites to bolster your posts....I suggest you do what you do best....google the topic and share your findings, an example is the subwoofer thread in which there was discord on the need or benefit of using a subwoofer and then much later acknowledgement that a subwoofer does in fact improve the music experience... the same applies here.....

 

oh wise one, even you agreed that a good two-way speaker could provide decent and audio correct sound without the need for a subwoofer; but that is a story already put to bed.

Back on Topic - Break-in

SUMMARY
(1) some metal flakes initially, while dealers don't recommend 1,000 oil and filter change it could do some good; level of good unknown or validated.
(2) synthetic oil supposed to be good for 10,000 miles, my recommnedation is every 5,000 including itial change at 5,000
(3) drive easy and vary speed first 1,000 miles
(4) avoid hard braking first 200 miles.

Peace Brother and good luck in your future ...you really don't want ulcers.

P.S. Copy and paste ?, It is called research and corroboration and proof of concept you know kind of like a researcher does.

 

One through four is exactly what I did, and do.

 

awesome , great job

Just finished my 1000 mile break-in period. Drove it easy at varied speeds and avoided hard braking for the first couple hundred miles. I burned 14 gallons of fuel which I estimate equals about 400 engine miles. After burning another 20 gallons of fuel, I plan to change the oil and filter. The Lexus has been flawless.

 

A lot of good video references in this thread. I have to say I have a number of favourite channels on YT that I regularly watch.

First on the list, the Car Care Nut and I've watched every single one of his videos, some more than once because they have so much interesting content, but to do so and be a follower of 10,000m oil changes means you'll continuously get beaten over the head for those choices from this guy, a constant reminder from him "please don't do that". He should be mandatory watching for any Toyota/Lexus owner. But I think its summed up well when he says (paraphrased) the dealer will give you the cheapest bulk oil they can and the only requirement is that its "brown and slippery", LOL. This guy is just so intense about having everything proper and with 20 yrs of rebuilding Toyota engines at dealerships, I can't help but listen and follow his advice. His car reviews are also excellent, one of the few car review channels that also does a deep dive into the mechanical aspects of the car including an underbody examination. While I can appreciate an attractive woman in a short skirt telling me how nice a car drives and how convenient the cup holders are or aren't, I find more value in his approach.

The Motor Oil Geek I've seen many, but not all of his videos. If you are into oil analysis, he's your guy. Every video he does involves putting various oils thru some kind of experiment and then having a lab analyze the oil. Compares old oil to new oil to see if oil breaks down just sitting in the bottle, different viscosity oils and their effects on horsepower and wear, viscosity changes during an oil change interval, changes in additive levels during an interval, and on and on. Interesting stuff if you like the science behind it (even if his experiments are one offs, not statistically sampling a fleet of cars).

I Do Cars is another interesting Youtuber. Many of his videos involve tearing down a destroyed engine to see the internal damage. A lot of them involve people letting their engine run low on oil. Engines run low on oil typically because they leak or burn. Engines leak or burn excessively often because they had poor maintenance. He's another one that's constantly preaching to avoid disaster, change your oil.

Aside from oil related themes, for diagnosing issues, Check Engine Chuck is also interesting but its mostly fairly technical dealing a lot with the computer systems and scan tools. But my favourite for potential DIY diagnosing is South Main Auto. Small town mechanic dealing with practically every problem a car can have, I've learned a lot about vehicle wiring and electronics watching him troubleshoot.

D4A (Driving 4 Answers) is another YT channel that deals with engine technologies of all kinds, new, old, and experimental.

Of course there are plenty of others like Scotty (I used to watch him a lot, but lately his videos are less working on cars and more yakking), Car Wizard (Interesting stuff on European and Asian cars except "hell no I won't touch a BMW", lol), Hoovie's Garage (Buy an old high end luxury car cheap, wreck it a bit more, get it fixed and sell at a loss (but make money making videos on it). More humor than anything but get a insights into the perils of owning older high end mostly European cars. I watch Dave's Auto sometimes, mostly bigger engines and diesels but sometimes interesting.

Curious to know what the rest of you have for your regular car YT channels that might related to this topic and why...

 

The majority of the particles are not ferrous. Yes, this does give some credence to the first oil change to remove metal filings .If 1,000 mile is a critical interval, then car vendors would still have it. Sure it does some good, but no one cab quantify even the experts. And the video had nothing basically to do with metal flings only that break-in oil was no linger used. one of the primary reasons was most cars were now leased and leases were really really poor on getting maintenance done. This makes one wery about buying a previously leased car.


So yes, an early oil change will help extend the life of an engine, an pretty hard fast fact. But again no one has any data long-term as to how much it helps with newer
engines.

So my summary for break-in is pretty accurate, see this post for a refresher on OP's original question: https://www.clublexus.com/forums/nx-...l#post11749863

The 1,000 mile change can be added as an option , but should not be belabored as the stalwart point in the break-in process.

This is a guaranteed way to make a good engine burn oil. I've built many engines for street and competition (even won some championships and set fast trap speed for a privateer at Daytona). Never baby an engine you want to last. All that will happen is the rings won't seat, the valves won't seat, and the engine will run poorly until these issues are remedied with a complete rebuild of the rotating assembly. I have a very specific method of breaking in a new engine, and it doesn't take long at all. This guy has it nailed: http://www.mototuneusa.com/break_in_secrets.htm. The wife's GS F was going 140 mph at full throttle with less than 30 miles on the odometer. The wear over the last 130k+ miles is documented in this thread: https://www.clublexus.com/forums/gs-...-uoa-here.html. It does not burn oil.

The last engine I used the procedure outlined above was a 1993 GTS Celica. It burned a quart of oil every 1000 miles. Never again.

 

The Lexus Owner's Manual agrees with me - Easy Break-in. I have heard of the hard break-in you describe and some people subscribe whole heartily to that break-in method. But Lexus and the majority of Auto Experts agree with the easy break-in. I respect your opinion, but I am siding with Lexus on this one. See below from Lexus manual:

I really couldn't care less what the manual says. The factory has ONE goal. Replace as few engines as possible under warranty. They DO NOT CARE if you burn a quart of oil every 1000 miles (there are MANY documented cases of Toyota/Lexus telling customers burning a quart of oil in 1000 miles is "normal"). They DO NOT CARE if your engine runs inefficiently. They ONLY care when they have to replace an engine under warranty.

My mileage does vary. I have built championship winning engines with the break-in I use and the same one Motoman uses. They DO NOT burn oil. They DO NOT have ring sticking problems. They run over 200k miles without any issues.

Do as you please, but don't tell me the factory recommendations are for your benefit. They are not. They are only for the factory's benefit.
