Found this interesting video explaining why we should break in properly.



I don't know how I'm going to cope, I've never done it before! The first thing I want to do is rev it out and experiance that new engine!

I think maybe I'll load up on Red Bull/snacks and drive backroads for a couple of days to get it out of the way.

How will you cope?
 
I would follow the Toyota Instructions for the GR86.
For the GR Yaris, there is no Maximum Rev Limit, but gentle throttle applications, lots of timely gear changing and lots of engine braking too, as this puts a totally different load on the Piston rings and will give you the best running in seal.

Drive away gently after you start the car, don't leave it ticking over.

Varying the Revs and Never Labour the Engine.

Most importantly, go gently until the Engine Oil is up to temperature, but the Transmission takes even longer to warm up.

Full Throttle up to Maximum revs is something you should slowly build up to (620 Miles in the GR Yaris, I think).

The Nissan GTR has Plasma Coated Cylinders, hence the special run in procedure.

I hope you love your new GR86. 🤩
 
When I picked up my RS new, they just state that you shouldn't rev "much" over 4k but as importantly not to hold a specific rev for hours on end.

A varied rev range will help the engine bed in far better than doing 500 miles at 70mph on a motorway etc. I still wait until the Oil temperature and pressure guages are at their normal operating temperature before having too much fun even now. It's just good practice.

It does make the excitement of "being free" that much more exciting though!

Have the CEO in the passenger seat for the first 1000 miles so she can enjoy “the new car”, and keep it vacant for the next 5000 😉
 
and there are engines where you cant really run them in ;)

honda 150 mile bed in....not 1000 miles!

i can remember running in my megane 300edc on the scott 500 :ROFLMAO::ROFLMAO:

to be honest dont think i have really "run in" any engine as per the "rules" even all the ones i have built over the years :eek:
 
Unlock. Get in. Observe the normal warm-up procedure, but other than that just drive the thing.

Will any of you be doing a 1000 mile oil change? I'd probably look at doing it on the driveway and then take it to the dealer for its regular service intervals...

Yeah, probably will. Going to be a long term keeper so want it in rude health. (y)
 
I think a few/lot of folk will be seeing the GR86 as a longterm keeper, and will look after their cars above and beyond what Toyota require. I’m guessing service intervals/requirements/costs etc will be similar to the GT86 🤔

Maybe @Richard Mckay and/or @Lauren could give their thoughts on giving the GR86 a good start in life and keeping it healthy longterm 🤔

Yeah I will do the same if it's not on the service intervals.
 
Is there any benefit to changing the diff and gearbox oil at 1000 miles? Looking to keep the car forever.
 
For me that's a step too far - but down to personal preference. Generally those oils will last a life - but maybe someone knows from the GT
 
This is the official breaking in procedure according to the UK GR86 owner's manual posted elsewhere on this forum:

■New vehicle break-in driving (the
first 1600 km [1000 miles])
The performance and long life of your
vehicle are dependent on how you han-
dle and care for your vehicle while it is
new. Follow these instructions during
the first 1600 km (1000 miles):
●Do not race the engine. And do not
allow the engine speed to exceed
4000 rpm except in an emergency.
●Do not drive at one constant engine or
vehicle speed for a long time, either
fast or slow.
●Avoid starting suddenly and rapid
acceleration, except in an emergency.
●Avoid hard braking, except in an
emergency.
The same break-in procedures should
be applied to an overhauled engine,
newly mounted engine or when brake
pads or brake linings are replaced
with new ones.
 
Yeah I was just thinking that BMW M cars change the diff oil at the running in service but they probably have a different type of LSD

Yeah I know I just wondered if the car was enough to tempt you away giving your GT86 history

Not really, no. I will review the new GR86 when it comes out and I'll bet I'll like it. But, I don't change cars frequently as I had the GT86 for 8 years. Will probably do the same with the Yaris. Plus I definitely do not want to spend any more money. Him indoors will kill me. 🤣
 
Only new car I've had I didn't follow the run in procedure. I'd let it get it to temp then kick it's head in. It was a Fabia vRS Estate which were known for burning oil. Mine didn't use a drop when driven hard and was faster on track than other Fabia's at the time. Oddly it did use some when driving normally.

The bike I babied for the first 800 miles, where each 100 miles meant 1000rpm more to use. That was hard going on a bike. I got the running in oil change, then rode normally and it's been good. The GR86 I'll be in the middle of. Let it get to temp and drive normally but I won't use all the RPM, certainly not near the limiter for the first 1000 miles, then it's fair game after that. It's all warrantied anyway.
