Recently, I have bought a Corolla 2 Meter mileage is 94000 KM. Previously probably having thick oil e.g Havoline 20~50.
I have shifted it to Caltex Formula 10~40. After 3500 KM it reduced the oil approx 1/2 letter.
But apparently seems engine have no issue e.g no back smoke etc etc and also there is no leakage.
Please suggest me expert opinion. Should i move back to 20~50 and stick with same by changing oil on some low mileage initially e.g 2000 KM.
Or can i also use some addictive as well to resolve this issue.
Thanks in advance for your valuable time and response.
