Torco TBO SAE 40 Premium Break-In Oil Bottle - 1 liter, (Case of 12) is a blend of hydro-processed petroleum base stocks that clean and prepare new surfaces. Since the first start up of a new engine is critical to its life expectancy, TBO utilizes specially selected additives in order to protect vital race engine parts during the first startup. The TBO cleansing agents "scrub down" any contaminants left in the new engines from the production process and assure good cleansing of freshly machined parts. It uses protective anti-wear chemistry and allows mating surfaces to gently make contact during first new startup. The Torco TBO provides the proper film for new bearing protection and is made to withstand viscosity break down in order to maintain good strong parts separation films. This oil can also be used as a consistent monitor control oil or "reference oil" for engine studies using an engine dynamometer. The Torco TBO contains a high percentage of "Zinc" anti-wear chemistry for proper valve train and new cam break-in protection. It is recommended for applications that call for: 0w40 5w40 10w40 15w40 0w50 10w50 20w50 and turbo applications. It is recommended to be run for 30 minutes or longer on new or rebuilt engines for racing, high performance or street applications. It is also good for running in engines prior to switching to synthetic based motor oils.
