Every TSP engine comes with 12 quarts of break-in oil at no extra cost. Proper break-in oil is crucial for ensuring your engine seals correctly during the initial startup and break-in period. Most standard oils lack the necessary additives, but TSP ensures you have what you need for a successful break-in.
