Breaking in new 2026 Supra

[IsThatASupra?!]

Hey guys,

I recently just got the new 2026 Supra at 9 miles from the show room. And I've never really bought a car brand new before, so breaking in the car is something new to me. I have seen older forums stating to not rev over 4500 RPM for the first 1200 miles just very recently.

Unfortunately this being my dream car I got carried away and would take my friends on joy rides to show them the car. I haven't used the paddle shifters yet but I have been flooring the car a bunch. Its around 350 miles now, and I hit orange area of the speedometer a bunch (ripping it). Should I be worried? What issues can arise? Definitely takes a lot of discipline to drive 1200 miles under 4500 ?. Also I couldn't find that in the manual if someone can screenshot. Overall any one truly think I'm in trouble here?

Thank you again!

I'm not technically minded enough to give any expert advice here - but just wanted to say, I did the same thing. It's so hard to not want to drive Supras hard. I'd think as long as you're letting the engine warm up for at least 5-6 miles first with easy driving, and not redlining repeatedly on drives you're going to be ok.

Ya I usually like to let the car warm up so it under 1000 rpm but I'm low key worried I messed up really bad. From this point forward though I will be adhering to the recommendation of the manual. but my first 350 miles with this car which is prob the most important was not really very kind

You will get opinions on complete opposite ends of the spectrum. You're fine, plenty of people have punched it straight out of the dealership lot and been fine. Just drive the car how you plan to drive it for the rest of its life, break it in to what it's regular use case is going to be

totalled! and your oil level will only read to 3%! now you'll need to use 10w40.

I followed the break-in instruction on the Supra, and changed out the oil at 2000km. Max i did around 75% throttle, cylinder pressure helps rings bed in. No issues at 21k km.

The 2016 Volvo XC90 in my family however did not follow it at all, European delivery car with 3km on the clock, 210kmh on the autobahn for hours right after 350km, and 3 laps of hard nurburgring driving before reaching 1000km. It's at 200k km now and zero engine internal issues, and doesn't burn oil, 15k km oil change interval.

There are also guys that go big turbo right after and doesn't seem to have issues.

If you are keeping the car for a long time then just follow the manual. If you're gonna trade it in after 3-5 years then whatever ?

A hard break-in is the BEST break-in. As long as you let the car fully warm up (while driving, not in your driveway) before you put a lot of load through the engine, you'll be fine.

No need to let it idle to warm, in fact it's worse for the car than to do it while driving, and once it's warm, have fun.

Yea but what oil is in it.

 

[MisterSkiz]

Warm it up, beat on it with high RPMs - change the oil at around 1,500 miles...boom done.

No break in for me. You’ll be fine.

All "broken in" already from factory. The bit in the manual is basically to make sure brakes and other things bed in correctly, and if anything would to fail, you aren't driving like a madman when it happens. Basically, lawyer shiat.

I'm sure some internetz people that think they are smrtr will cry and say that is false, and I will not care.

Here's a good explanation about why "drive it like you stole it" makes no sense when it comes to breaking in new cars.

I agree with all of this. The running in process is for the driver/rider and brakes not the engine. With modern plateaux honing of cylinders the rings are the only things that need to be "broken in" and that's 90% done by the time you get the car/bike. Every other component in the engine is wearing out from the first time it's started, not wearing in. Years ago with the bore finishes of the day and softer valve seat materials things were different. Rings needed to bed in and polish rougher cylinder walls and valves would settle into their softer material seats and tighten up a little but with the latest super hard valve seats and bore finishes it's not the same. Same as re torquing cylinder heads, MLS head gaskets finished all that. In days past you'd drop the break in oil and it would be full of fine material and looked a bit like Mica paint in the paint gun pot and the Mag plug would have a fair amount of paste on it. Not anymore. The initial changes come out quite clean, the odd bit of machining swarf occasionally but none of the suspended wear particles from days past.
Naturally industry representatives will sing the old tunes about break in because they'd be foolish not to. You can't end up in trouble by preaching the "cautious" approach. I knew the CEO of a large Japanese motorcycle brand here who also used to be a world class race engineer in his day and he'd always get annoyed by customers with sports bikes that claimed warranty for high oil consumption which happened often when the rider babied the thing around during break in. Why the hell do they buy a sports bike and ride it like an old lady he would complain. He was correct.
