AMSOIL Introduces New Z-ROD Synthetic Motor Oil

AMSOIL INC. of Superior, Wis. now offers synthetic motor oil engineered specifically for classic cars, muscle cars and other high performance applications.  Available in 10W-30 and 20W-50 viscosities, AMSOIL Z-ROD Synthetic Motor Oil features high-quality synthetic base stocks and a proprietary additive package tailored to prevent wear and provide maximum protection during storage.

AMSOIL Z-ROD oil is formulated with high levels of zinc, and zinc is critical for wear protection in the flat-tappet engines of classic cars and other earlier-model high-performance vehicles. AMSOIL Z-Rod provides exceptional protection for flat-tappet cams, lifters and rockers.

Damage from rust and corrosion due to long periods of storage is another issue common to classic and vintage cars.  AMSOIL Z-ROD Synthetic Motor Oil is formulated with a unique blend of rust and corrosion inhibitors to ensure maximum protection during storage.
