Castrol Professional notes that the fuel-specific gap in average mileage widens once more as cars get slightly older. In the 5-6 year bracket, diesel-powered cars travel an average 11,132 miles between two oil changes â 19.4% further than their petrol counterparts, travelling 9,322 miles.
There are exceptions which depends on where you live and how you drive the vehicle. For those exceptions, one may get the oil change more frequently ~3-3500 miles. It doesn't hurt the car if you change the oil more frequently but that's a personal choice and will cost you more in maintenance costs.
