Passenger Car Motor Oils

Heavy Duty SAE 30W Motor Oil

Heavy Duty SAE 30W Motor Oil

Made with the highest quality, hydrotreated, paraffinic lubricating oils and a technologically advanced additive system, which includes detergents, dispersants, viscosity improver, anti-wear and anti-friction agents, and oxidation and corrosion inhibitors.

Benefits of MAG 1 SAE 30W include:

  • Reduced friction for excellent protection against engine wear and improved fuel economy
  • High resistance to viscosity and thermal breakdown
  • Fights volatility burn-off to minimize engine deposits and exhaust emissions
