Hi everyone. I have Honda city 2014 1.3 basic manual driven almost 142000. Now the situation I was running the car on 5w30 and in recent oil change due to something which I still can't figure out when car went for the oil change the amount of oil was very low and since I wasnt the one to take the car to mechanic he put 20w50 which has me worried a lot. Now the car has no blow it's running fantastic. No leaks no nothing and now it's not reducing oil. I want to change it to 5w30. Is it ok if I do it and what brand would be recommended
