Hi all and a very Happy New Year to you....

Just a question on oil consumption...My 645 seems to like a drop to drink...I don't have an oil leak so I know it is down to liking a drink..Is this normal......Thanks.

Yes - although usually a result of a leak rather than burnt in the combustion....................

(Engine oil I assume?)

My E92 325i (3.0L) loves a drop of the dark stuff as well.
Seems a common issue with the petrol engined cars. Mine is going through a litre of synthetic between 2K and 4K depending on driving styles. Tootling around town it holds the oil level much longer, but then if I do a spirited motorway drive the oil level drops much quicker.
And this isn't a leak at all, certainly burnt through the engine as the exhaust tips are always filthy! Thick black soot and gunk covers the internals and even external of the twin pipes.

I now keep a litre (courtesy of Opie Oils on here) in the boot.

Just check that the crankcase vent is working properly, oil consumption is not uncommon but there is a point at which it becomes excessive. BMW do publish the "acceptable" values for this so worth checking.

If the CCV is blocked or failing, you'll have excessive consumption and a load of dodgy smoke from the exhaust.
