20-50 full synth after the first change. Not a drop used in 2200 miles.

We use BMW 15w50 Full Synthetic right out of the box per ScooterBob.
We get in in the handy 55gal size so the price is not too terrible.

Precious needs ca. 0,1-0,2 litres per 1000 km. I doubt that she burns it - the only spot to loose this amount would be the drive pinion´s shaft, as it is sourrounded by a brownish sauce that - I suspect - is not only chain grease but some engine oil, too. Hard to say. Does anyone changed the o-ring there? How complicated could that be?

I need to take a closer look at mine there too, I suspect the same thing.  It would explain the loss with no puddle in the garage, only happens when running.  I haven't changed that but I'm guessing it's not too big of a deal.  Drain oil, pop the side plate, pull the chain and cog, change seal.  Just need a new seal and side gasket.

I drain the oil out of my airbox regularly.  (Of course, I push mine a little harder than most...)  ;D

To isolate the chain sludge I would thoroughly clean the chain and switch to chain wax for a while. If you still have sludge it could be the seal. Another solution is a dye that you put in the oil. It will show that engine oil is lubing your chain. It has been decades since I used it but I'm sure they still make the dye.

I only use dry teflon chain lube.  It cakes up a bit at the front sprocket but it looks like more than than.  I've never had any oil at all in the air box.

Oil in the airbox is usually from overfilling the crankcase.

Haven't had any oil used up by the running of the bike in the last 1 1/2 years since new. Only spits some oil out the crankcase breather this Summer when revved hard - must have just brimmed the oil during the last change in Winter and it's expanded now. Will set it right this week - due for a change anyway moving to 300V full synth from semi synth.

The usual splattering of oil from the chain lube near the front sprocket - initially thought it was a leak from the kick-shaft seal, but no worries since using the spray lube - some gunk to clean off after the first ride after chain lube and it's OK until the next spray.

Yup, I've had it less than a year and already spoken to my mechanic about it.  I'm running 10w40 right now as an experiment so I'll swtich back to a 50 weight oil first but if it's still losing oil we'll dig deeper.  One of the bummers of the auto decompressor is you can't do a simple compression test.  You have to do a leak down test and I don't have the equipment for that.

Dye? Exellent idea, I didn´t know this trick. Thank´s a lot, I´m going to get that soon. Foolproof solution, tailor-made for me  ;D

Oh!  Missed that earlier.  Yes I've seen this mentioned and used before on other forums.  A good idea to be sure.

Probably available at your local auto shop too.

Or this trick:

Existing chain lube shouldn't show up and it washes away with water when you're done.
