@Xulfiqar or @capsat ..
Using 5w30 API SN oil in 1L Vitz 90+k ODO. It is reducing oil, about 1L in 1,000 Km...
But there's no smoke from exhaust, blue or black, dry compression test is normal same in 3 cylinders. Car runs fine too and very good mileage.. just sometimes white smoke in dead cold winter start for a while which seems normal water vapor.
No leakages from the bottom on the ground seen.
So what can be the problem of oil getting reduced ?? Any ideas to fix/check ?
Also..
At idle there is vibrations at times, already cleaned throttle body. But that isn't the issue. used to be smooth. Any ideas?
