718 'running in' period
Discussion
Guys
Can't bring myself to read the documentation, but would like some advice if there is a run in period for the 718?
Read somewhere to keep it under 4k for some set amount of mileage... but would like some general guidance (as opposed to a multipage argument on 'drive like you stole it' vs 'driving miss daisy').
Thanks!

no seriously... is the recommendation to take it easy for a bit or not? last car I bought brand new I had to drive it lightly for 400 miles.
I dont suppose taking it easy will do it any harm will it....as opposed to redlining it from brand new.
It might also depend whether you bought it outright are keeping it past warranty period, or if its a PCP/Leased dump and run or trade back in after 3 years...
Either way, personally i would run it in for a 500 miles gently if it were mine.

“Herr Koop, you do not understand (that I already knew). When we do our engine test, the metals inside the engine never reach the temperatures they would when driven on the street since the test session is fairly short".
Ah, so best to give it more welly when the engine isn't up to operating temperature then?I'd previously thought it best to allow the engine, and oil, to heat up as a cold engine, and oil, promotes more wear.
Discuss?...

could have read the whole manual by now
From memory when I got my new 981 Cayman, the recommendation was to not exceed 4k revs for the first 1250 miles (2000km)
The general recommendation is to not exceed 4k revs until the oil temp is at least 80 degrees, which in a 2.7 doesn't get to down the road too fast and is probably the reason why I keep getting overtaken by cyclists and milk floats on the way home from work!!

oh, and I haven't bothered to read the manual either - there's no need.
I can't see that, cars are so complex today that you cannot possibly understand all the facilities and options your car has. Having spent a pretty vast sum on the car I'd want to be sure that I was getting the best value out of it. If the car in question was a Ford Pop or Caterham then I might think I wouldn't miss anything, but it's inconceivable now unless you've had a similar car before.To give an example, unless you've had a Cayster (or perhaps 911) before would you really know where the bits were to deal with a puncture? When I was buying my car a private seller only found out there were storage compartments behind the seats on a Caymen when he was cleaning it to sell it!

Not to put too fine a point on it but to pass over the only real authority on this running in business -- Porsche and what it offers in the owners manual -- and instead solicit the advice of "net-experts" is frankly crazy.Can't bring myself to read the documentation, but would like some advice if there is a run in period for the 718?

As a "net-expert" but with the desire to help you maximize your enjoyment from your Porsche for as long as possible I'll try to keep this as short/brief as I can: Generally you treat the car with a modicum of empathy for the fact it is a complex assembly of parts that to deliver their best without risk of degradation or damage should be up to temperature. So no WOT blasts from cold.
A new engine's biggest problem is friction. With friction comes heat. So for a while -- in the USA I think the "break in" period is 2K miles but here I would insert the advice to consult the owners manual -- avoid high RPMs for whatever break in miles are given.
This does not necessarily mean you drive the car like "Miss Daisy" is in the passenger seat. Once the engine is up to temperature a bit of load -- as long as this does not involve lugging the engine -- is beneficial as this puts pressure on the rings and forces them against the cylinder walls to facilitate the break in process. (Essentially controlled wearing in.)
The idea is to give the engine a blend/mix of different types of loads and RPMs so the wearing in occurs with no localized overheating or excessive wear.
Another problem for a new engine is a new engine sheds metal. From every internal surface. The concern is say under high RPM high load conditions the pressure of the rings coupled with high temperature and some compromise in the oils' ability to protect due to contamination (which a new engine is also prone to do) will result in a large fragment of metal coming loose from the cylinder wall. This large fragment of metal can damage ("score") the cylinder wall or damage (even fracture) a ring.
The RPM restriction also gives the cam lobes and lifter bucket faces to develop surface finishes that can resist any wear for hundreds of thousands of miles.
And properly broken in these engines can last a long long time. I essentially followed the above with my new 2002 Boxster and here it is 14 years later (soon to be 15 years -- I bought the car in Jan 2002) and with over 306K miles the Boxster engine (in fact the entire car) still runs just fine, consumes a reasonable amount of oil, and still is a pleasure to drive.
Lab and field tests have confirmed this break in process is real and continues for thousands of miles beyond the nominal break in period. But with a proper initial break the engine is safe from pretty much anything other than sheer stupidity the owner can throw at it.
Last but not least unless forbidden by the owners manual I recommend an early oil/filter service. As I touched upon above the new engine sheds lots of metal. There is a filter but there is a concern that when the engine is started up cold and the oil pressure is high this filter may be bypassed and unfiltered and dirty oil is routed to the engine. This ain't good. Also, as I touched upon above a new engine's oil suffers from heavy levels of contamination. (An oil analysis of my Boxster's oil with just 4K miles found around 7% water in the oil. 7% is nearly a half a quart of water in an approx. 9 quart volume of oil. This water was from combustion contamination. BTW, this level of contamination caused me to adopt a 5K mile oil/filter service schedule which I think has helped the engine resist the ravages of time and miles.) An early oil/filter service removes this contaminated oil which helps ensure the break in process continues with no unhappy surprises arising from contaminated oil.
Yes Rockster very sensible advice. I spoke to the workshop manager at my local PC and he said if it were his vehicle he would do an annual oil change. I will follow this advice as my Cayman will be a weekend car doing approx 5K even though the first change is at 2 years or 20K per the service schedule. After spending £60K on the car why would you not spend a relatively small amount of money on an oil change after 12 months ?

k me!Manuals are too long (see what I did here?). The'yre meant for reference not for reading cover to cover. For the majority the 718 is unlikely to be their first car so a handover from the salesperson should suffice.
I asked the OPC if I should have an early oil change. Was told that it wasn't necessary and only owners of higher stressed cars do it occasionally. I'm going to ignore this and have an early oil and filter change because it can't do any harm and makes me feel better.

I might give some insight although no 718 experience directly. I had a break-in period on both of my cars last year, one is brand-new turbo (VW TSI 2.0 Turbo) and other one is rebuilt 986 2.7 NASP engine.
Been told for both engines, a bit different instructions for break-in periods but the general common sense for both of them was "keep under 4000 rpm as much as possible, in the first 2000 miles) and try to avoid frequent but short trips anything less than 10 miles ideally.
For VW, firstly, I have been told turbo engines benefit from higher cylinder pressures to seat the piston rings, so first few hundred miles variable RPMS but not much abuse. Mixed journeys necessary, both motorway and urban. After break-in period, then run the car on really high revs if possible to avoid carbon buildup!
For 986 2.7 engine, I have been told strictly keep rpms below 4000, first 2000 miles again, and really monitor the oil consumption. This came from my engine specialist who has built several m96 engines and race/cars before. After the first oil changes and 2000 miles, run the car with varying RPMS, enjoy it but again try to avoid frequent short trips.
For both cars, I had to change the oil/filter in the first 5000 miles to see how its performing. Interesting part, VW TSI engine consumed a bit more oil than porsche in the break-in period but currently both cars settled, oil consumption is extremely low.
I agree with ownership period though, if you are not gonna keep the car more than three years and if its under-warranty, all these might be a bit too much.

Bit frustrating no one replied with - “I’ve got a 718. I’ve read the manual. The answer you’re looking for is...”
OP. I’ll read the manual and give you the highlights as soon as I can.
Truth be told it’s a bit of a shame there was no serious and genuine summary of facts in this thread
