Engine OIL Change @ Service Center

Yes, You give your bike for service every 3000Km and the TVS Service center guys change the Oil For you. You return happy, Indeed very happy.
Well, Wake up...!!!
Don't put Oil at that TVS Service center..!!
Simply give your Bike for Service, Without Oil Change...!!
Go to a Fuel Station, Buy the Recommended Oil, Then put it in...!!
Next time you will see your Mileage has Improved, Engine is Smoother, and You are assure you have changed OIL...!!
I am recommending this because I saw the Quality of OIL Used and Benefits of putting that OIL out of service station. My Mileage improve 5Kmpl by just OIL Change to Synthetic Oil + Smoother Engine.
Earlier I changed to Semi-synthetic and the Mileage improvement from TVS Service center oil was 3Kmpl.
