People saying to change your oil at 1000 miles on new vehicle.

To the original question, there is no proof, it's an unprovable thing. Even if an OEM of some oil company tested it it would likely be some sort of accelerated test and not as relevant.

It's all rumor and innuendo.

Back when the Jetta was new I ran the factory fill nearly 10,000 miles and it looked perfectly fine, good even.

It also wasn't the dealer oil (which at the time was Castrol Edge P LLIV).

If you go watch some factory engine assembly videos (there are many on Tube of You) you wont see any Moly lube, it's all engine oil. its also very clean and done in part by robots.

The whole early change is legacy information IMO.

But you pay you money and do what you want, its your car,

That would mean then there's no assembly lube used either? I seriously doubt that. It is typically the assembly lube that would spike moly in a FF UOA.
 
I went 10,000 miles on the new 2024 Rav 4 hybrid and the oil still looked clean. The dealership changed the oil and filter. IMO no need to change oil early with a new vehicle. With the hybrid the gas engine only runs half the time unless you are on a long trip. We did take it to Florida and back to SD one time on a vacation.

You didn't provide any proof as the OP requested. Do you have any data showing that engines with oil and filter changes at 50 or 100 miles last longer than engines that have their first oil change at 10,000 miles?

Okay, let's see the data that BITOG members filling their engines with boutique oils will also have their engines last 400,000 miles instead of 300,000 miles.

If this place actually was all about data and data only, then this forum would be shuttered within a week.

People have been seeing metallic debris in the first drain from new engines for decades. To many people, removing that debris quickly sounds like common sense. If it doesn't make sense for you, then don't do it. It's that simple.
 
No proof for engine longevity because it’s not necessarily about that, but break in and early oil change seems to matter in applications where top rated performance needs to be guaranteed, like in the aircraft industry.

Here is my quote with a link to the material from another thread:

You don’t need to have data right in front of you to know that having metal particles of various sizes floating around in the oil is not optimal.

But the data must be out there or various professional engine builders, performance motorcycles, even aircraft engines would not call for early break in oil changes.

Here is one from Shell

Take a look at this article for advice on breaking in an aircraft engine, the type of oils to use and why this is so important to the smooth running of an aircraft.

The observable data suggest to me, that changing the oil early doesn't have any significant effect on the longevity of engines. I have to believe the vast majority of people do not change their engine oil early and therefor, there are plenty of engines motoring along with 200k+ miles without any oil related issues that didn't have their oil changed early.

The OP asked for proof. We're at 148 replies and no proof was offered. Only, it's seems like a good idea. I take exception when someone says that you must do something without offering any data to support their viewpoint.

Ok so you're claiming new engines are no longer assembled with assembly lube?
Click to expand...
Nope i'm saying it's oil, oil is all the assembly lube you need if the engine is going into service. You can verify this yourself on youtube just as i said.

Here i'll start for you:



You let me know if you can find one with this mythical moly that is adding to the factory fill, i'll be happy to watch, but i haven't seen it yet for a FACTORY engine.

So no one uses assembly lube anymore? Interesting, I might have learned something new today. Now if you're talking about "break in oil" we might be in agreement.

In theory they oil filter should catch that, but as mentioned, if you want to rely on that feel free, but some of us don't.

Many small engines still have a break in spec / time, probably because they have no oil filter.

The fact is all the debris will, pass through the oil pump before the oil gets to the oil filter as well as web the filter by pass valve opens. It seems most people will never see the results of frequent oil changes , fancy oil filters and top shelf or boutique oils .

How does extra abrasion help bed in the piston rings?

some styles of knife sharpening rely on the slurry created by the friction of the blade and stone. It gives a finer edge, a sharper edge.

I know that an engine is a different environment.

I am for the 1st short interval oci. or at least the filter changed

What would be oil related issues to you?
 
Back to the OP's question. Because engines wear due to use, an early oil change can at best mitigate a tiny percentage of wear.

But we know a few things now, don't we? With the use of quality oils educated motorist can mitigate clogged piston drain holes, fast timing chain wear, early cam phaser failures, rapid rod bearing wear, failed low tension piston rings and more.

"If" you don't know what problems your engine is susceptible to, or what oil the factory fill is, the $40 early oil change is a great time to put in a high quality oil.

Unfortunately, there are many engines failing early, often around the 100K mark, including legendary brands like Toyota, BMW, Ford, GM, Honda/Acura and more. I do not want my engines to be among them.

Why let this get a foothold? Because we know this starts immediately.
