718 GT4 "Run-in Period" - Confused!

[Twinfan]

Mine's just over 2 years old and is pushing 9k miles.

If you've got 'em, drive 'em...

Planning on visiting Wales on the upcoming bank holiday to try and get some Mileage on it, Got my first ever trackday booked for July, so need to get it run in!

Not going crazy out there, just some nice scenic driving, just hoping that not too many people have had the same Idea...

Totally. 6k in 12 months, crack on and enjoy!

Just put some more oil in my GT3 (992) which is now on 5000 miles. Ran it in to the letter and it uses about 500ml every 1000 miles (including track use).

My 718 GT4 I hammered it from day 1. It never used a drop.

My GT4 uses 100ml per 1000 miles including track days ....

Doesn't that concern you, or is it within limits?

As for 500ml every 1,000 miles that sounds like a rebuild coming. Is that usual for GT3 consumption?

No, it’s perfectly normal and will probably do 6 figure mileage without any issues. High compression, high revving naturally aspirated engine used as intended.

[Twinfan]

Yep, and the new 4.0s in the GTS/GT4 like a bit more of a drink compared to the older stuff. Perfectly normal for them too.

Mad Scientist's was/is an outlier

[Rob P]

Good to hear. Just topped mine up, used 500ml in 3000 miles.

I think 1 litre per 10,000 miles is very good .... accepted that I change oil on average every 3,500 miles to allow for track days ....

It may say 0.8l per 1k km / 600 miles is in spec. But, personally, if I had a modern F6 car that was consistently using that much, I'd be fairly sure that there's a problem. Nearly a litre in 600 miles is a lot.

Suspect those figures in the book are designed to keep punters out of the OPC until the thing is pretty much dead / provide some leeway to allow OPCs to say 'all perfectly normal as per the book, go away' and reduce warranty claims.

Why is that high oil consumption normal?
Where is it going? It must be squeezing past the rings and out the exhaust surely? So either they're loose or worn or there's some method in the 4.0's madness?

Comparatively my 2.7 981 has never needed any oil in 58k miles. Apart from capacity, what's the difference in oiling these two flat sixes?

Well as far it goes my car will be a year old in 3 weeks & has just over 3k on it , not needed to put any oil in

If you check your handbook you will see a similar level of consumption is also deemed 'normal'. It's not particular to the 4.0.

[Twinfan]

The common consensus is that it settles down as the miles increase. I've topped my car up twice in 9k, so that's 1ltr of oil. Although it has had two oil changes in that time.

I'm expecting consumption to be minimal for the rest of this year.
