this thread is crazy. someone even said 0w oils are bad lol its so hard to believe any of these break in procedure because people are all trying to justify each. My head is spinning. Regardless I already have 1000 miles on my car so whatever is done is done.

So, If I'm understanding this thread completely, if I don't break in my engine properly then my FR-S will grow up to look like this?
Is that about right? |

DEBATE ENDED
Here are photos from an FA20 engine broken in the "drive it like you stole it" way.

You dont know if he beat on it cold, when he changed the oil, how the DI system was working, what type of fuel he used, or any other factors that should be measured in relations to these engine that have blown even when people followed the break-ins. BTW 'drive it like you stole it' is not the proper way to do a hard break-in there is science and theory behind it and it has been proven to work on some engines. |

I would know. Those are my pistons from my engine.
I don't beat on my cars cold, but once it's warm, it's always game on. Driving it like you stole it, or hard, or via the motoman method or whatever isn't below 4k is essentially the same. There's isn't a science to this, but a collection of ideas formed from personnel experiences, which is what those pistons are portraying, my personal experiences. Now onto the details: 93 octane fuel 0w-20/0w30/5w30/5w40 (changed within the first 500,again at 1000, again at 3000, again at 5k, and every 2k up to 15k.) DI was functioning fine. FI for 8k miles NA for the rest Automatic. |

適切なエンジン回転数についてGoogle Translate: For proper engine speedSo yes, in Japan the break-in period is only 625 miles. And they helpfully remind Japanese drivers not to exceed redline thereafter :-). Also amusing from a quick glance it looked to me like the Japanese owner's manual is a fair bit different than the US manual. There are more steps for many explanations than in the US manual. Really detailed steps, like they wrote the manual for people who have never driven a car before. (They explain things like how the cars with an automatic transmission will creep forward a bit when you put it in "D", even if you don't press the accelerator pedal.) |

Im picking up my BRZ and driving it 1,000 miles home. I know the biggest thing about this is overthinking it but will this be a problem?

No. Take it easy and follow what the manual says. Keep below 4000rpm for first thousand then build up the revs from there and try and avoid keeping at the same revs for a long period of time. Don't get too paranoid though and enjoy

That's true. The engine did blow from severe detonation.

And I'm guessing not from the drive it like you stole it break in procedure.
You have 8K miles on the engine with forced induction. Since you didn't specify, I would guess those pics were not taken prior to going FI but after you blew it from going FI? Btw, who was your tuner? |

Blew on Visconti Tuning. Believe malicious intent was involved.
Yes photos were taken after it grenaded under boost. Went full lean. |

Tech writers wrote the manual, reviewed by lawyers and managers, revised, and lawyers and managers get final say. Engineers will be consulted via email, phone, and meetings as to technical data, but we get ZERO say about what is put out for public consumption. After all, what do we engineers know about talking to people... Just to be clear, I don't work for Subaru and I didn't sleep at a Holiday Inn Express last night, but I am an engineer. Specifically a systems engineer working in the aerospace avionics field. I speak from that experience.
