I've heard both sides of the argument, stating that break-in periods aren't needed these days, to some saying they still help improve long term durability. The owners manual says 600 miles, anyone have expertise in this area?

Good to know. I've been mostly staying within the guidelines. Drove it a bit hard when I was test driving it, and showed a friend sport mode once, but other than that I've been trying to be nice to it. Soon as I hit 600 I'm driving to see you guys and get a buncha stuff

The cars have to come broken in at least somewhat. Think of all the dick heads that test drive a brand new car. Luckily I got mine with 11mi on the odo and didn't even go through PDI yet. I was pretty easy on it for the first 500 but didn't hesitate when I had to pass people.

Yeah my car had 7 miles when I test drove it, and I test drove it hard cause I was also comparing it against the Civic, Mazda 3 and GLI. But I bought the exact car I test drove and nobody else had driven it in the 2 weeks I was deciding, so I'm good to go.

Ive heard it both ways--some say be easy on it during the break in period and others say its better to drive it hard during it, and swear by it. So really its hard to say which one is the right way to do it...

Found a great video that explains why break in periods are necessary for cars:

Both are super informational.

There are many people on each side. I've own mostly new cars, and do light driving with occasional high rev acceleration. I think modern engines will have issues with either method.

Also the manual is likely written by lawyers, to the lowest intelligence level, with the simplest methods. I doubt engineers have much say in what goes. Many ideas of engine breakin dont take in account the higher precision, better oils, parts, and understanding of metals and physics, that were much more limited 40 years ago

my car had 40 miles at the time i got it delivered

anyways, i followed the break in guideline per the owner's manual and i just hit 600 miles.
should i change the engine oil now or am I good to start revving higher than 4k?

Maybe bogus, but can't hurt.
Also, i believe the engines are 1) run on a test bench before install and/or 2) run around a quick test track at the factory (or at least around the storage yard, lol)

I was bummed mine had like 250 miles on it. who the **** knows what it went through before me- but took it anyways. .
