What's the suggested running in procedure? I guess it's in the manual?
Has anyone got their own recommended ideas on what to do to get the engine decently run in for longevity?



I haven't seen a manual yet but I'm probably going to do a filter and oil change after 100 or so miles on my own. Does this sound a good idea? Then I'll stick to Toyota's service intervals.

I'd say the usual. Just drive it normally. No labouring and all that.

I reckon full revs by 500miles, though some say thrash it from the start to seal the rings.


Modern engines don't need runnning in as such.

I think you'd be pouring money down the drain if you changed your oil after 100 miles. Tolerances and all that have considerably improved since the good old days. In all honesty I'd just follow the service schedule.

you need to keep revs below 4k for the first 1000 miles. it wont be easy but after 600 you can start giving it some.

Read the handbook today whilst sitting in a GT86. Running in is as follows: No going over 4000rpm for first 1000 miles and have to use varied driving rather than driving for a 1000 niles at one speed. Going to take me ages to do a 1000 miles, do 5 per day normally.

Get in it, set the SatNav for Aberdeen avoiding Motorways, drive for 20 hours, enjoy !!

Does make you wonder what sort of test drive experience you would get if you were in a new demo....did they keep you guys sub 4000?

My test drive car had 250 miles the first time and about 400 (500 after I finished)miles on the second time. I red lined it many times, many many times
and I took it past 100mph

I hammered the poor car to redline a few times.
Also slammed on the brakes when i didnt see a speed bump - all at 20 miles old.

No wonder ex demo cars are cheap.

I plan to take a very long journey to the coast and back to put a few miles on it the day I pick it up. It gunna be difficult to keep to the manual if you need to overtake a tractor or slow moving vehicle or something. I presume its just a warning so you dont go overboard.

Nope, the sales guy didn't mention it, gave it a fair amount of throttle well over 4000rpm, didn't say a word.

No fair enough. And just imagine if they had said "If you wouldn't mind keeping to 4000 rpm please Sir/Madam, we are running her in"!!!!!

Good excuse for a sales exec to take it home for a few nights that!!!

You took it past 100mph. Didn't the dealer give you a test drive on the road, rather than on a track only?

The run in process is all about heat-cycling. The metal parts all expand/contract at different temperatures/loads and effectively mate together over a period of time.

This is why you don't want to put the engine under too much load (eg flooring it from low revs/revving to limiter) in the first 500 miles. It is also important to vary the revs up to about 4000/4500rpm - no higher initially.


Sitting on a motorway for a 400 mile trip is not perfect. Part of heat cycling involves the engine cooling in between runs Regular commute trips are ideal - ie 50 miles each way with the engine completely cooled when it is switched off, then brought up to temperature with varied revs.


This is what I was taught by an engineer and it has never let me down. What everyone does is of course entirely up to them.

Hmmm. My daily 'commute' is only 10 miles each way.I may have to get up a little earlier and take a more circuitous route for a few weeks.
