One possibility if the rate of oil consumption suddenly jumps is a problem with the oil breather.
The triples have both an oil separator and a breather into air filter enclosure.

My Mx5 only uses oil when its breather restrictor is 'blocked', need to remove and soak in kerosine overnight and it is then ok for another 30k miles or so.

There is no detectable leak or smoke.

Kerosine is a good solvent...

Wanted to revive this thread as I'm suffering the oil consumption issue.. is there anything new anyone has learned to solve this? Mine is a 2007 Pug 107 with 120k on the clock. It runs absolutely perfectly despite the high mileage, just uses way too much oil, no blue smoke, just drinks it. Seems to be a common problem but nowhere on the net can I find a fix, and obviously Toyota/Pug/Citroen will tell me the usual bull about the engine being worn and nothing to do with them.

So I've seen faulty oil control rings, try using 5W/40 oil or similar, blocked oil breather and other speculation but what's the real answer please?

The only way it can loose oil is via an external leak or burning which will give smoke.


Check for any sign on visible leaks of there isn’t then it must be burning oil

I would do a compression test to check the rings initially. Could be a head Gasket could be valve seals?

But compression test first

the old test and still used by me start the engine warm it up remove the filler cap is there much air/oil fumes (pressure) escaping if so this is a good sign the sump ventilation is blocked every engine has to have some kind of vent going back to the inlet , not looked on the mrs 107 yet so no idea where it is

Our 2012 bug has been using oil at the rate of about a litre every 100 miles for ages now, with no signs of a leak and no smoky exhaust. It reached 95000 miles, sounding like a bucket of nails when cold but coming ok once warm. It has a hard life doing 500 to 600 miles a week. We made a concious decision to just run it always keeping it topped up, it lasted for about 15k using it until it ran the big ends (suspected as not looked at yet) at 95000 miles. It has always been run on 10/40 semi synthetic and always changed at 8 to 9000 miles. Presently looking for a replacement engine for it.
