How many kilometers does Toyota Prievia change its oil?

The standard is 5000KM oil change ~ slow throttle response should have nothing to do with oil.

Too much carbon deposit on the throttle, or the gasoline tank has not been changed for too long, will also have an impact (if you want to change the gasoline tank, be prepared psychologically. The gasoline tank of this car is extremely expensive! Originally 1 100+! )

Another point is that if the gasoline you add is not good, it will also have an impact ~ it is best to go to some regular gas stations to refuel ~
