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 racing engine parts during the first start-up. TBO cleansing agents "scrub down" any contaminants left in new engines from the production process and assure good cleansing of freshly machined parts.
This product would be ideal for owners of vehicles that require high-performance engine oil with a high zinc content during the first few hours or days of engine operation.
