Will do, I will even leave them a compact camera and SD card so they are not able to refuse.

Whoa, that's a lot of oil usage.

I noticed my gen 2 used some oil compared to other cars I've owned (all with upright engines)

I'm on about 1L per 2800 miles. Which I think is pretty reasonable. It used a lot more during winter when I was only doing short runs. It's drastically improved as the weather has got warmer and the engine is up to operating temps faster.

I'm about to embark on replacing my own plugs, so I'll share my results. If they're coked up etc.

Hope your problems are sorted soon Glen. Don't like hearing about bad Porsche ownership experiences!

Mine's a June '09 car and uses about 200-300ml between services (2 years). I do about 8,000 miles a year

This is typical of internet scare mongering. OP you should have kept your 997.1.

I've covered over 150,000 faultless miles in a 997.C2S including many track days (80 miles round trip per day on average) and never even had a leaky RMS.

Having said that your 997.2 is operating within manufacturers specification. Drive the wheels off it and stop being OCD Very Happy

FWIW, I drove about 8000 miles in my 997.2 before I even checked the oil level. It was a bit low when I did check, but still above the min, so I added 1l which took it closer to the top. I then did another 2k miles before going for the bi-annual OPC service inc. Oil change.

Worth checking, as you do not want to be overfilling.

100% 400ml. Only know this for sure as I had to double check the book before a top up earlier in the week


Funny we were having this discussion at Dinslaken the gen1 guys all thought it was 200ml per seg the gen2 guys all thought it was 400ml per seg so it might be just that .

600 ML PER 1000 miles seems the porsche recommended but they also say up to 1lts per 1000 miles is not excessive Surprised my oil usage has dropped significantly since swapping to millers 10w50 I have assumed its for the reasons Baz recommends and uses it. Thumb Thumb Thumb

Very pleased for you to have done '150,000 faultless miles' I would like to be in that position, unfortunately that is not the case. Were your car to be using a similar amount of oil then you would have consumed an additional 250L of oil by now between its services - acceptable for a £70K+, I don't think so.

I do not consider myself OCD but do not believe that amount of oil use can be anything but bad for an engine long-term. As I said earlier I have seen my father take apart enough engines to see that. Reason for getting it looked at now is that I believe 5 months of monitoring the use is enough for an accurate record and whilst it is still covered by a warranty.

Certainly not my intention to 'scaremonger' just reporting a genuine and real issue with my car on the forum I read a lot.
In doing so was hoping for advice - which I have received and am grateful for. Additionally, to see if anybody else had previous experience I could use going forwards.

Actually my previous 911 was a 996 not a 997. I agree with you on the point of keeping it. I do have an honours degree in Hindsight haha.

I do still enjoy the car but at the moment it has taken the shine of it a little. Once it is sorted out or concluded it will either be back to being my Pride of joy or traded in.

Regards
Glen

You misunderstand. I was not inferring you are internet scare mongering at all just that owners of 997.1 are petrified because of the things they read on forums. 95% of gen 1 997 never suffer engine failure according to figures from a US law suit against Porsche America.

I imagine the figure is even lower on gen 2 cars. I'm afraid if that oil consumption figure is within Porsche spec you are definitely worrying about zilcho. Keep well and enjoy your fine car in good health (built a few engines myself - some use oil some don't) bye

I have received some very good advice from forum members for which I am grateful.

as a result I have cancelled the car going into Porsche Exeter and it is now booked into SCS Porsche Specialists. I drove the car to them today and after discussing the car with them feel better that it will be evaluated independently.

They will have the plugs out do a leakdown and compression test and borescope photographing everything for the warranty.

Despite being busy they took the time to listen and have a look at the car before booking it in. Will keep those that are interested informed of the outcome. They did say that 620 miles per Litre of oil with no leaks was not good.

Regards
Glen Wells

To previous poster if my car was doing 2800-3000 miles per litre I would not be concerned I change my oil every year/4K miles so it would not be a problem. Do not think that amount would cause any long term issues.

I got the usual dismissive response when I complained of high oil consumption a few years ago. If I wanted to use a litre in 600 miles I'd have bought a two stroke.

The replacement engine hardly uses any and I do about 12k miles a year. Thankfully these problems are rare on the Gen 2.

Did you have total engine failure or did they replace due to excessive oil use?

Perversely seems it better to have engine failure. Was the process getting a new engine hassle free? Was it an OPC?

With Porsche warranty I find anything that actually fails is ok, but they weren't that interested when parts were just in the way out. I've (later) paid for parts a few times where I'd highlighted them multiple times whilst the cars were under warranty.

For my engine the OPC were great, but it took a while to get them and Porsche to agree to replace the engine rather than repair. After over a month negotiating, the engine took under a week to arrive and fit.

I'd not long bought my used car from an OPC, so I was ready to give the car back if they couldn't resolve it to my satisfaction.

When mine was in Colchester having it's major, they mentioned my thermostat was sweating, but was unable to replace it under warranty, until it actually started to drip!! Haven't they heard of preventive maintenance? That meant I could have driven the 80 miles home to find it had started to leak, then they would have had to arrange transport to collect it and take it back Confused

I hope the person that has purchased mine, get's a result on an engine replacement when they realise it's not much different from a two stroke engine nooo

Im interested in this thread myself. I've had to top my 997.2 up recently. I haven't been monitoring its oil usage quantity but after reading this I think I will now. Good luck and hope it's a simple fix 👍🏼
