AMSOIL INC. has added a member to the DOMINATOR® Synthetic Racing Oil family. New AMSOIL DOMINATOR 10W-40 Synthetic Racing Oil is a durable formulation designed to provide maximum horsepower without sacrificing engine protection in racing and high-performance applications. 

AMSOIL DOMINATOR SAE 10W-40 Synthetic Racing Oil is shear-stable and heavily fortified with zinc and phosphorus additives designed to protect critical surfaces in racing engines. Its proprietary friction modifier helps reduce friction for maximum power and cooler-running engines, providing outstanding extreme-temperature protection.  

“DOMINATOR is a proven line of racing oil for people who push their engines to the ragged edge,” said AMSOIL Market Manager – Powersports & Power Equipment Len Groom. “We designed DOMINATOR to deliver exceptional protection in extreme environments, and that’s just what it does.”

While some companies reserve their most exotic racing-oil formulations for professional drivers and provide only a tame version for the public, AMSOIL DOMINATOR Synthetic Racing Oil is available to all racers. The same products used by professional, corporately sponsored AMSOIL racers are available to everyone, regardless of their level of competition. Recommended for use in racing and high-performance engines operating on gasoline, alcohol, diesel or other racing fuel where an SAE 10W-40 viscosity is recommended. Check the owner’s manual or engine builder’s recommendations for correct viscosity. DOMINATOR Racing Oil is also available in 5W-20, 10W-30, 15W-50, 20W-50 and SAE 60 viscosities.
