Running-In Oil is a specialised SAE 30 mineral oil formulated specifically for newly rebuilt engines. This 5-litre oil plays a crucial role in the initial break-in period, providing carefully balanced lubrication that allows proper bedding-in of piston rings and other moving components. The low-detergent formulation prevents cylinder bore glazing while ensuring optimal wear patterns develop between moving parts. Particularly suited for classic and vintage engines, this running-in oil helps establish correct clearances and surface finishes during the first few hundred miles of operation. The mineral-based formula is fully compatible with heritage engine designs and provides essential protection against scuffing and premature wear during this critical period.
