Question about 2007 Mazda 6
Since the power generated by the turbo depends on the volume of combustion gas generated, look into your fuel delivery system. Your engine might not be receiving the required amount of fuel. Check your fuel pump, filter, injectors, and lines.

If this is the intercooler there is a recall on it. I took mine in, but there is an eight week waiting perid for the part.
Hope this helps

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.

Mazda say that if your Mazda 6 consumues less than a litre every 900 miles then it within tolerance.
However these cars have a complicated induction mechanism controld by lots of diffrent vacume pots that are inturn controlled by servos, when any one of these becomes faulty the pressure balance between the exhaust side of the turbo and the inlet side becomes inbalanced, resulting in oil being forced through the turbos bearings. Its that simple lol!
The first thing I would check would be the swirl control valve, In the inlet manifold, This gets fouled up by the exhaust gases getting recycled by the egr valve(exhaust gas recycler)
Sooty deposits mix with oil coming from your turbo and jam it closed restricting the amount of air into the engine, and reducing power as well as creating black smoke from your exhaust.
So my advice would be to get your egr valve proffetionally blanked off, and have your induction system checked over.
Hope this helps as I am sure this is a very common problem!
