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.
Some dealers indicate the car has &#147;break-in&#148; oil installed at the factory. Those dealers recommend a first oil change at 7,500 miles. The &#147;break in&#148; oil is reported by those dealers to have different additives than common replacement oil. The different additives in the &#147;break in&#148; oil are reported to be beneficial to the new engine.
