The Torini TC210 Engine comes out of the box with four Torini engine seals. The engines are sealed from the factory and cannot be opened. This is done to ensure fair racing. 
The engine is shipped without oil. Oil must be added before starting. We recommend first running in your engine with Torini 4S Run In Oil and then switching over to Torini 4S Racing Oil to ensure the highest possible protection and performance is achieved.
