Japanese Company Honda Engine oil scam a bad service by Honda Azad pur

Honda's bikes SP125 BS-VI, CB Shine SP, CB Shine, Dream Yuga & Neo have engine oil capacity of 900 ml, but they are using 1000 ml package of engine oil and the worst is instead of charging for 900 ml engine oil cost they are charging for the complete package (1000 ml) in every bikes from their customers. They takes extra price for 100 ml engine oil from customers per bike and the cost of 100 ml is Rs. 32. The company "IDEMITSU" which is supplying engine oil to Honda has 900 ml packing also but still Honda takes 1000 ml packing and using it for 900 ml engine oil capacity bikes. This is nothing but a plain scam according to me by following unethical way of doing business and make profit. On every servicing of said bikes they are charging 10% more cost to the customer.
