changing to Mobil 1 at any km mark will give a very smooth and crisp feel to the engine, if done properly along with engine flush.
its debatable how much wear and tear it will avoid now on, but as the saying goes better late than never
again in some extreme and rare cases the thinner oil can cause some havoc wrt engine compression also
Mobil 1 safe limit for change is 7-10 k kms though one can push it safely to 20 k kms also under normal driving conditions without any issues
My vote for Mobil 1 if you intend to keep the car for long.
