991.2 C2S issues

[Audiofishboy]

Hi - Its a first post from me, but i was wondering if anyone out there has had any issues with the .2's engine. I purchased the car ex-dem. from Sheffield OPC and have since covered 4k in it. In the first 3k it asked for a litre of oil which i thought was excessive, and then in the last 1k it has asked for another! I have witnessed smoke coming from the exhaust regularly and have had a huge plume billow from it after a 'spirited' exit from a slip-road. The car was booked in last week with them and the report that has come back says nothing is wrong, the oil usage is within tolerances and to quote 'this is common with a flat six engine sir" I am due to pick it up tomorrow, but this doesn't seem to sit right with me. Agreed, there is no oil leakage from the engine, but the blueish tinge from the exhaust would suggest something akin to turbo oil seals failing?

Ive just come from an M5 Competition Pack which used only 2 litres in 26k, and this naturally seems odd with the C2S. Am i being paranoid or is the OPC trying to fob me off?

Regards
Peter

Not really relevant. It my 997.2 did not use 2 litres in 40k miles and 4 years (other than scheduled changes). Needed a top up occasionally but only 200 ml or so at a time. My 991 has yet to use a drop in 10k miles and 15 months.

Thanks Tuffer - its relevance i guess is that a modern engine should not consume oil at that level - especially if it has only seen road use

Just keep an eye on it. My 991.1 hasn't used any oil in the time I've had it. My old RS4 used to go through about 1 litre every 2k miles.
Its true that some modern cars are meant to use some oil these days but plumes of smoke does make me wonder if all is well?

You have a rock solid warranty so I wouldn't be overly alarmed and just keep an eye on it. It may well get better the more miles you put on it.

My 991.2 C4S has not used a drop in 3k miles and no blue smoke at all, something must be wrong I'd say

OP, do you park your car on a slope? I sometimes had no choice but to park my 997.2 Carrera S on quite a gradient and I would get huge plumes of smoke on start-up. I freaked out, made some enquiries, and was told by a Porsche technician that "it happens because the oil drains past the piston rings when parked on a gradient; when you start up it burns that excess oil off. It will also use a bit more oil when parked like this so keep an eye on it."

Maybe completely unrelated with your car, but you never know.

@SL550M no - its parked on a flat drive. I guess i'll just have to keep an eye on it. In the back of my mind ill always be wondering that its a first generation engine design and maybe all the niggles are yet to be ironed out

From my experience some engines use more oil than others for no apparent reason.
1 litre in 3k miles seems fine to me.

If, however you are getting plumes of blue smoke from the exhaust when warm I would consider returning the car.

Yes, but the next litre was burned in just 1,000 miles. Does sound a bit thirsty TBH, although many of the factors that make engines burn oil - warm-up etc. - will obviously be exacerbated by the onset of colder weather.

Establishing how they were run in/driven for the first 1000 or so miles normally gives a pretty good insight

Well I'll pick her up tomorrow and keep an eye on things. Hopefully it will settle down and hope that it's not a frailty with the new engine. Thanks for the input folks.

I've just ticked over 3000miles in my 991.2 C2S and it's used no oil at all. I bought it new so I know how it's been driven (carefully warmed up but still driven quickly on occasions when warmed up). Absolutely no smoke from mine either. I'll keep an eye on the oil level from now on.

Indeed... Maybe there is something to this running in lark!

I have a 991.2 C2. Had it from new since March 2016, had the oil changed after run in (~2k mls) and it didn't use any oil during the run in period. It now has 8k mls on it and I've topped it up with about 400ml in that time. Not had any blue smoke from the exhausts.

I would be more worried about blue smoke from the exhausts as I wouldn't necessarily class that as normal, unless it's been overfilled with oil? Given that it's an ex-demo you may want to check how it was run in and used during that time.

Maybe take it to a different OPC for a second opinion.

[Tony 1234]

Probably because the OP's car was a demo there lies the explanation to his problem?

Never warmed up first before a spirited drive with circa 200 test pilots?

[grumpynuts]

Unfortunately, dealer demonstrators are never warmed up before the throttle is mashed into the carpet, especially on the dash home at night. OP, keep an eye on it, and keep a diary over the next few weeks and see.

I think even a British Leyland dealer could see the problem.

My OPC is getting it's 991.2 GTS in April but it's not available to be booked as a demo car until June. I assume this is because they want it run in before they let people out unattended in it for a day at a time...I

Folks - i still seem to have an issue and i wanted some feedback from you. Below are two links to videos of the car being started. One is a first start in the morning and the second from a restart when the car was perfectly warm. You will see in the videos that the smoke produced is blueish indicating oil and although the smoke clears, my concern is that this should not be happening on a vehicle such as this. There have been many instances where the smoke produced is way more dense and of greater volume than that shown in the two videos; its just that i didn't have time to get back out of the car and video the damn thing.

OPC in sheffield are raising the issue with Porsche direct, but at the moment i am being told that this is "a feature of the flat six engine! and since i haven't owned a porsche before, i should not be concerned. Its produced as oil settles in the bores!" Is this a feature? does anyone else with a 991.2 have this? The car has bellowed smoke several times on a full bore upshift and I'm being told that this is normal.

The car has never seen a track and is only used on the road within normal operating parameters

Sorry for the questions, but this just doesn't seem right? - am i being fobbed off?

Cheers
Peter
