All TSP engines will include 12 quarts of break-in oil for no additional cost. Proper break-in oil and procedures for your engine are just as important as the build process! The break-in oil allows for proper ring sealing against the cylinder walls upon start-up, as well as for the break-in period once the engine is up and running. Most off-the-shelf engine oils do not have the necessary ZDDP additives to allow for proper break-in of a new engine, and we want to take every precaution possible to ensure that your new TSP engine receives a proper break-in! We also offer Driven Racing oil for your new engine once your break-in is complete. We recommend using the HR2 conventional non-synthetic.
