  • Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. For example, several popular oil manufacturers produce racing oils offered only to NASCAR* teams. DOMINATOR Synthetic Racing Oil is already formulated to a high level of performance. It provides maximum performance and superior protection to all racers, regardless of their competition level. The same DOMINATOR Synthetic Racing Oil that is used in the engines of AMSOIL corporately sponsored racers, including Bryce Menzies and Brad Lovell, is available to everyone.

  • Consider the event, application and viscosity needs. When competing, the vehicle owner is responsible for determining an appropriate oil service interval. DOMINATOR is not intended for long-term use in passenger cars/light trucks.
