Read evidence and context
Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.
Discussions that contain suggestions

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suggestion
Worried me a bit so I called the OPC and they said it should settle down as the miles go on it, and advised I checked the oil more often (or at all…!).
Leading evidence: 'Check oil more often (or at all…!)' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check oil more often (or at all…!)' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My Cayman is almost a year old. I was returning home today after a weeks 1000 mile tour of the Lake District, and my low engine oil light and warning message came on stating the oil was at its minimum level and requires a litre to top it up. The car has just hit 3,500 miles. I have run it in very carefully for first 1800 miles and its been driven pretty respectfully over the remaining mileage. Is this normal oil consumption?
Yep, lots of US comments on Rennlist about it.
My GT4 needed a top up recently, delayed by the fact I had an oil change at 1800m, and I'm around 5k miles now.
Perfectly normal by the sound of it.
Be careful topping it. I added 0.5L and it's at the perfect level of one bar below the max. 1L would have overfilled it.

Cheers - much appreciated
3200 miles in I got a level warning. 800ml was required. Worried me a bit so I called the OPC and they said it should settle down as the miles go on it, and advised I checked the oil more often (or at all…!).

Can anyone confirm that this is the correct oil for the 4.0?

Yep that's the oil which I got from my OPC yesterday. It was only a quid more than the cheapest online I could find and it was peace of mind. I also got to have a browse at their cars
