I am using Axio Luxel 2007 1.8 from past 8 years its been a wonderful journey. I bought the vehicle on 32k odo and currently it is on 300k. NOW the issue I am facing is the oil level starts dropping after 1500kms and needs a through refill. There is no leakage in the Engine as it was completely checked by the mechanic, no smoke from the engine and engine never got overheated.
Oil Grade I am using is 10W-40 ZIC. PS i never changed the grade because 10w-40 was doing fine.
A friend recommended to change the oil grade to a more thicker version as the car is driven 3lac kms
Kindly suggest what would be the possible reason for the decrease and which oil would be best for the car
