The amount of oi l an engi ne uses will vary wit h t he way t he vehi cl e is driven i n addit ion t o normal engine-t o-enginevariat ion. This i s es pecial ly t rue during t he fi rs t 16,100 km (10,000 mil es) when a new engine i s bei ng broken i n or unt ilcert ai n i nt ernal components become condit ioned.
