rev the engine to 5000 rpm before break in period - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Though there's arguments for both the under 4K and the "Drive it like you stole it" break-in methods, I think a gentle break in with occasional runs to redline when the engine is fully warm is a good way to do it.

There is evidence that shows babying a new engine does more damage than driving it hard during breakin. I have never had any issues driving my cars hard during the breakin period.

Enjoy the car, drive it, and don't worry.

This thread is lulz.

You want to get the engine nice and warm then drive it pretty hard in a higher gear (4+) with heavy acceleration under load and engine braking. Don't abuse it but drive it hard. This helps seal/seat the piston rings and the engine braking helps remove miniscule debris from the cylinders. A car with properly broken-in piston rings will have more power, better fuel economy, reliability and burn less oil. You need to do this when the engine is brand new (~20 miles) or it doesn't really matter. After that, drive it however you want, just dont cruise constantly at the same rpm.

In the rare circumstance that something breaks, it's better to find out sooner rather than later when it's not covered by the warranty. It's either defective from the factory or it's not... it's not like part X could break at 70 miles, but then be perfectly fine forever after 1000 miles. It should be noted that every engine coming from the factory has already been redlined (and probably more).

I did a "stepped" break in in mine.

For the first 200 miles, ~50% throttle and no more then 4k rpms. 2-400miles, 60% throttle and no more then 5k rpms. So on and so forth until redline and full throttle. You're not only breaking in an engine but the entire car.

4k miles on it now and constantly taken to redline

That's not how you pick shift points and that's not when you have the most hp.

That only in the American manual then, because i read the manual i got with my GT86 front to back and there is no mention of any break in period in the entire manual.
I also checked with my local Toyota dealer and he also said that there is no break in for this car.
Seems strange to me that in America there is a 1000 mile break in necessary and in Europe we can go full throttle from day 1.

You likely lost about 30 hp. I would get some Grimmspeed and Greddy stickers on the car asap to get your 30 hp back.

Its just there to protect toyota from lawsuits

OP: you're fine. All cars are essentially broken in at the factory. Motors are tested at low and high rpms. Maybe another reason for the break in procedure in the manual is to allow you time to get use to the car before you start drifting sideways at 7000 rpms.

Ocala FR-S · 11-02-2013, 08:14 AM

You're also supposed to vary RPMs during break-in. I've heard no good argument for starting off with an extended road trip that was probably on a highway at a steady RPM. Even so, no one can really tell and it won't break anything.
