bro sorry but what are you talking about? nobody changes mobile oil after 1000kms. its always 5000kms till you change the oil. and what you are suggesting is highly impractical. nobody spends upto rs.3000 on oil change every 1000kms. and yes i know its not about money, i know that, but any good synthetic mobile oil can easily run for 5000kms. yes, some people argue that in summers one should have it changed when the car is driven 3000-4000kms but in winters one oil change easily lasts for 5000kms. it is also advisable to have your air filter and AC filter changed aswell after every 5000 kms.
if you can put in the effort of changing oil after every 1000kms thats good for you but its completely unnecssary. Fully Synthetic mobile oils are specifically designed by the company to last for upto 5000kms. you are sincerely advised to get your facts correct.
