AoA,
I'm having a issue with my Altis 1.6 manual 120k driven,it's consuming oil frequently,after running 600 to 800km it's consuming 1liter of engine oil and currently I'm using zic 20w-50 after suggested by a mechanic and know, after checking 2 to 3 oil changes the mechanic is saying that the rings and valves of car have to be changed otherwise it will damage the engine,kindly suggest what to do and how to resolve the issue with the oil.
