Quick question as i've read accounts that these things can drink oil at an alarming rate (1 litre/600 miles?) but other reports of almost no consumption/top-ups required. Does it vary enormously from one car to the next?

It can also vary over the lifetime of the car. Mine used to be a bit of a drinker (although nowhere near as bad a litre every 600 miles!), but now it's settled right down and top ups are much less frequent.

My 3800cc S uses approx. 0.25l/1000miles.
Don't forget these engines have a more sophisticated oil supply system - no mechanical oil pump, but an electric pump which delivers oil when and where it's needed in the engine. So I would say the variation we see amongst owners could be down to driving style rather than differences in engines!
They have a handy digital oil-level gauge, so it's easy to check if stopped on the level at traffic lights (need about 40 seconds on idle).

Oil consumption in my gen2 S is zero except when my piston ring fault appeared.

In 6k miles (14k-20k) I've added about 1l of oil. Not a problem.

In 23k miles mine hasn't used a drop. No modern engine should. I don't care what the dealers tell you.

Wow that's amazing. It's not just what the dealers tell you - the oil consumption is documented in the Owner's Manual too! I don't have it to hand to check...
For the record, mine has done 47,000 miles. I do very mixed driving from short 2 mile runs to work, 150 mile trips on the motorway and 20 mile blasts around the countryside.

You don t say what engine size.

Had several Gen 2 C2S and now GTS. All low mileage. None needed top ups between servicing, irrespective of type of driving.

I am told it depends on how the car is run in. Being too gentle and short journeys is often worse than being too aggressive. Like most things in life moderation is best.......

Sorry, it's a C2S

Will be putting about 300 miles/week on it so dont particularly want to be putting half a litre of oil in it every week

is that why some people are using more oil,the short trips where there engine doesn't get warm?
me personally I would never drive a performance car 2 miles to work let it sit cold all day and then drive 2 miles home!
none of my cars have used much if any oil and I never do short trips!i would even drive out my way if I have a short trip to make sure the engine is warmed up

I take it you are thinking of buying one?

If so bear in mind a PDK is virtually ipossible to over rev. Not so a manual. In addition to my previous comments, this could be another and more significant reason for excessive oil consumption......

It's a manual but no over-revs apparently, so if that's the underlying cause i should be ok? It's being prepared inc. 111 point check at OPC at the moment

My C4S uses as good as none. My C2S used a litre in about 700 miles, but with its new engine it has dropped one bar in over 3000 miles.

Try mentioning that to some BMW owners! Some of the E46 petrol engines had quite a thirst.

Assuming its a Gen 2 3.8 s, why did you need a new engine?

I would ask them for a print out of its historic rev ranges, it could make interesting reading.....
