I get the puff of smoke on start up occasionally but that always looks worse than it is anyway, with regard to the amount of oil used by it.

Nothing used on mine, but as already stated likes a smoke at startup....

Suggestion
The engine could be using oil but the oil lost to the engine is being made up by the build up of unburned fuel and water in the oil, these are from combustion by products.

Coverage and how to read this overview
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.

Serviced last Feb. 7k driven, and gauge in the check system, still says FULL.
Forgive me, for asking this question, but my last 911, was a 993, so was normal to top up, half a litre a month.
My Mk1 used next to none throughout our four years together. Probably because it was a proper engine with water cooling rather than one of those quirky and archaic air cooled ones....
Yep, mine never uses any.
I get the puff of smoke on start up occasionally but that always looks worse than it is anyway, with regard to the amount of oil used by it.
I have never had to top mine up between services. Neither did my mate who I bought it from. In fact it still has an unused 1 Litre bottle of Mobil 1 in the front, that was there when my mate bought it 6 years ago.
I run mine on Millers Motorsport now though.
The engine could be using oil but the oil lost to the engine is being made up by the build up of unburned fuel and water in the oil, these are from combustion by products.
You might want to have some oil analyzed to see what the water content is. These engines are rather cold blooded -- they take time to warm up fully and then they require tootling around town to get the engine (and engine oil) really hot to help boil off the unburned fuel and water.
Same reply really, on my third GT3, over 40k miles and can only recall putting oil in the 996 once.
They all smoke like Jack Duckworth avin a woodbine on start up though

There is a definite pattern here!
My 60K Mk1 GT3 uses no oil - none.
Its changed yearly so is always fresh. Its only driven on the road so I cant say if serious track work may cause it to use some?
