Diesel cars get more mileage than cars with petrol and diesel engines. Initially, you will get amazing mileage, but as the vehicle gets older, the engine performance decreases and fuel consumption starts to decrease.

If your diesel car has also started giving low mileage, here are some tips for better maintenance of diesel engine cars. You can follow that.

1. It is very important to clean the air filter
