Brake in.

[Tyson]

Hey seeing as the 86/brz/frs has been out for a little while now, just curious as to who actually followed the manual exactly and who just did what they felt comfortable with, and ofcourse what results you have seen from your method of running in the 86/brz/frs.

sorry if this has been done i thought it was slightly different to most posts about break in periods etc, im mostly interested what people have personally done and their thoughts.

Usually you gradually increase pushing the cars for the first 1500/2000 km, avoiding long amounts of time at constant speed.
Supensions, gearbox and brakes also need to be broken in, so you'll need to increase the pace as well in a gradual way...

"The manual says to take it easy the first 1000km, so I better grannydrive it and then give it the beans once i cross 1001km..."

I just don't see the logic?

I am going to ease mine into it, first few hundred kilometers I'll take is a bit easy and then gradually drive it harder and at faster rpm towards the magic 1000km mark. Babying it isn't breaking it in.

I figure the people writing the owners manual know more about the topic than I do so I followed their recommendations. It didn't make that much difference to me anyhow as that's the way I normally drive.

Some people say….

You should break in an engine by beating on it.

However, there's no way to know until engine reaches old age. I seriously doubt redlining it a few times during the break up would make the engine die at a younger age… it's quite rare to see an engine not make it to 300 000 km nowadays no matter how it was broken in.

Engine break in period done by the factory before it is mounted on your vehicle. Just drive it like you stole it! This is 2013 car, break in period is a myth! Get over it!

I like this idea. Have anything to back it up?

Drove it 200 miles, oil change at home. Drove it to 1000 miles, oil change again. I did 2 oil changes and looking for any sign of metal pieces from break in the engine, nothing in the oil pan nothing in the filter. Confirmed!

Follow the manual. I did but when I got to around the 600 miles mark I'd push it to 5k rp max, 700 miles 6k rpm, etc until I hit 1000 miles.

Nice, but nothing official from Toyota or Subaru?

This has been debated on every forum that deals with a combustion engine.. Always have a thread every new model year on the bike forums... Back in the day, I completely understood the break in period.. But if you've seen the thread with the FRS being built.. They roll every car straight on a dyno and run that shit straight to redline.. Along with other rpm points.. I just broke mine in with what I was comfortable with.. It hit the redline, hit the limiter, was up in the high rpms, but not like racing it so it didn't stay in those areas for extended periods.. I can look on gixxer.com for a article that's always posted when this comes up, about this guys scientific research on modern engines about breaking it in very hard, to use the combustion pressure to seat the rings.. I'll look for it and post it

^^ There's a difference between combustion heat and rpm. You can get lots of heat at lower RPM's under WOT and lots of load. The manual even says to give it some WOT acceleration up to 4000rpm during the break in period.

I kept mine under 4000rpm for the first tank, 5000rpm for the second tank, 6000rpm for the third tank and redline since.

I was getting about 550km's per tank, so by about 1600km's I was redlining. I'm not convinced it helps at all, but I was commuting about 100km's per day plus other driving, so I hit 1600km's in about 12 days. If I had to wait a month for that many km's there's no way I would have held out.

What does WOT mean?
