  • Use Z-ROD Synthetic Motor Oil in engines requiring either 10W30, 10W-40 or 20W-50 motor oil. Z-ROD Synthetic Motor Oil meets API SL and earlier specifications, allowing for increased levels of anti-wear additives. ZDDP levels in Z-ROD Synthetic Motor Oil exceed the limits of API SM and newer specifications
  • AMSOIL Z-ROD Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing AMSOIL Z-ROD Synthetic Motor Oil with other oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. Z-ROD Synthetic Motor Oil is safe for automotive seals. Aftermarket oil additives are not recommended for use with Z-ROD.
  • Because engines in classic cars, hot rods and other performance vehicles are generally modified, a universal oil drain interval recommendation for these applications cannot be given. Responsibility for determining the drain interval duration rests with the owner. As a general service guideline, the maximum drain interval for Z-ROD Synthetic Motor Oil should not exceed 5,000 miles or two years, whichever comes first.
