Re: 156 Jts Oil Consuption?
Your consumption is OK, as others have confirmed the TS engine uses oil, about 1 lt every 1000 km per the user’s manual.
The grey smoke you are seeing can probably be fuel, or slightly over fueling during hard acceleration.
I noticed last weekend that when my car went past the 4k marc, blue/grey smoke would come out the exhaust. I was frightened to death something had gone wrong.
Engine does not lack power at all & plugs aren’t fouling so that ruled out piston ring wear (plus it only does it past 4 k, neither before nor at start up, nor during normal driving)
Valve guide wear was also ruled out because it doesn’t smoke at start up neither after a long idle.
But then I remembered that my MAF & Lambda are out, so the ECU must be seriously over fueling the engine at high rpms.
I think you shouldn’t worry for now
