Proper Way to Break-in New Engine
I've done a lot of research on this and the best way to break-in a new engine is basically to drive it hard. I don't have the time to explain this but I encourage everybody who just bought an FR-S to do some research on the best break-in procedure. If you are babying your car you end up with slightly less power and an engine that won't last as long. Here is a good starting point: http://www.mototuneusa.com/break_in_secrets.htm

Oooooooor, do what it says in the manual and keep it under 4000 rpm for the first 1000 miles. I'm pretty sure Toyota and Subaru know something about the engine they built.

FYI: The FR-S is not a 10 year old freshly rebuilt motorcycle engine. Apparently the FR-S is a CAR with an engine that is vastly different than a motorcycle engine. Also, when you get this car it will have at least 10 miles on it and the engine will have been tested at the factory. Your website is an awful starting point, it is for motorcycle engines with zero miles on them, and is full of hearsay. There is nothing scientific about it. Plenty of other bona fide sources, like, oh I dont know, Toyota and Subaru recommend the opposite. There are already at least two long and hotly debated threads on this on this forum. If you have actual data or research papers those might help, also try the search button. Sorry to be so critical but you should not trust everything you read simply because it is well written and convincing.

My guess is the reason the manual recommends a soft break-in procedure is because they don't want to make it company policy to be recommending that people hot-rod the car... also, a proper hard break-in is very specific and riskier than normal break-in if not done properly, and people can't be trusted to do it properly.

c0rbin, I went with your method back when I was a teen. My Dad kicked my A** when I spun a bearing in my civic si hatch. Think I will stick to the manual.

I've had over 20 new cars and I have always been gentle with them for the first 1000-1200 miles and have NEVER had any mechanical problems. I also changed the oil every 3000-3500 miles.

There's already a break-in thread. And it's stickied.
But to add to this thread: It comes to what you want from the engine. To get the peak HP sooner at the expense of engine longevity, follow the aggressive method above. To get the most reliability and build up to peak HP later, follow the manual. |

^ No, you just made that up. The same thing that gives you more power makes it last longer.

This is why break-in threads suck so much.
