Kindly answer for my specific question at i have driven mira es 2012 model, 94000 km. Initially engine oil was toyota 0w20. 1 month back my car mechanic did not changed engine oil but said he has done it and after 15 days of maintainace my car started creating sounds when i went to a local mechanic he said there is no oil in the engine except for sludge he insisted for 20w50 considering the mileage and weather of karachi.he poured the toyota 20w50. After that there is jerks.and uthane mn different hai.

Kindly answer to my question. I have already read various discussions on your forum but they are really confusing as everyone has different opinions.
