theres a lot of controversy out there about this. some say that it takes a few thousand miles before its broken in, and one guy that has a site actually recommends to run the engine to its limit right off the manufactoring line...but he seems to be alone in that theory. if someone knows the link to what im talking about, please post it for reference, but i dont remember where i saw it at. common thought goes that the engine is decently broken in at 1000 miles, so you can push it after that. if your really anal about things, you can still semi nice to it for the most part until you do your first oil change, but im sure that opening it up a lil bit after 1,000 is totally safe for the engine. once that first batch of oil is out there, your good to go though :D.

congrats on your new subie, btw. and welcome to the club

i did the 1,000 mile break in on my new 04. it runs smoothly too. it is hard to keep it under 4K rpm. i only got above 4 like 2times. so just be patient its worth the wait.

personally, i did both. a little of this and a little of that. drove it hard, and grannyied (sp?) it. no problems to this day and i have 18 k on the car. just make sure that you keep up with the oil change. very crucial !!!

I think this --> break it in! <-- may be the link you're looking for.
I'm sure it's (this topic) been beaten to death, but i'm curious what you guys think of this quick-break-in method?

Hi all. I've been lurking here a bit. I picked up my Silver '04 wagon about a month ago. :D

I was told by the dealership that it was important to let the engine warm up, minimum 30 seconds or so. They said it lets the fluids get a chance to circulate before being worked. Is there any truth to that? They also mentioned at the end of the drive, to let the engine idle for the same amount of time.

I've been pretty much doing it by the book, I have over 600 miles on mine and I haven't gone over 4000 rpm (I know, someone smack me). I do get on the throttle pretty hard at times like freeway on-ramps (up to 4000 rpm).

I am thinking of breaking the 4000 rpm barrier constantly. What would you guys consider to be "reasonable driving?" How far over 4k should one go, and how often?

I had an FZR600 and I dont remember ever babying that engine. I do remember not redlining it until after the break-in period. That engine ran strong and never gave me problems.

I don't know why I don't just do the same with my WRX. I'm just too anal, I guess. It's my first new car.

Sorry for the semi thread hijack.

that is true with ANY engine !!! you need the fluids to circulate before adding any throttle to the engine. that is just common sense. metal + metal ( no lube ) = neg engine life......PERIOD !
