You're making a horrible generalization about people. We are literally grains of sand on earth. JSP is just an insignificant fraction of people and you're saying that people aren't knowledgeable on this planet?



Come on now.....You're better than this.


Literally just type. is car break-in period a fact or myth and you will find tons of topics of people discussing it. It's clearly not as clear-cut as you may describe if it's continuously argued.



Goodnight, Princess.

I can confirm the bold part.

Here's a good real world scenario.

I bought two trucks for the business on the same exact day. Same options all the way down to the color.

Truck #1 got driven 4 miles empty, hooked to an 18,000lb gooseneck and driven 2800 miles round trip with two drivers and never shut off.

Truck #2 stayed in town its entire life making 1 to 15 mile runs and sat in rush hour for 5 hours every day.

Truck #1 currently has over 487,000 miles as of the last pre trip on Friday that got emailed to me. Still has the stock rotating assembly and the heads have never come off the block.
Truck #2 has less than 90,000 miles and got an entire long block since the last motor had enough blowby to measure milage in quarts of oil from the rings gouging the bore to a point beyond repair. That was at 84,000 miles. That motor also had over 4,000 hours of runtime on it.

Y'all can say as you wish but this little scenario above has confirmed what i've been doing and why for the past years building diesels.

Every pulling motor i've ever built got primed with oil and dumped on a crank dyno and pushed to within inches away from complete fuckery the moment the oil pan went on.

Now, on a stock diesel it's still important but when you are running over 120psi, and enough spray to fly to the moon and back seating the rings gets critical. It's the difference between the rings welding to the bore after the pull or during the pull.

Yep you are in the 99.9%

Even on tech sites the vast majority of posters don't have a firm understanding. That is why they are on tech sites, to ask questions and learn.

It is continuously argued because the performance builders, racers, and machinists give advice that is opposite of the the salesman at the dealership who can't change a spark plug. When people hear conflicting information they go searching for answers. The myth of an easy break in period is nothing more than a set of instructions given to our forefathers thst has been carried on despite the huge improvements in engineering, machining, and QC. Parts don't need to wear in to each other anymore. That isn't debatable. I'm sure you will debate it though because you can't help yourself. Even when you admittedly have no clue what you are talking about.

I'm not saying I'm right, I'm just regurgitating what I witnessed as I searched., because on tech sites, you'll find both theories (not just people asking questions and being told your theory, but both ways).

Not to mention.....tires and are part of the break-in process and are constantly supported.




I'm more likely to believe numerous sources than one or a few people on JSP, sorry. It might be naive of me, or perhaps, ignorant, but it's rational in my mind.


Again, I'll restate that break-in periods were more relevant decades ago than today.

jesus, are you really fucking talking about this?

We can talk about Jesus if you would like to.
