Heavy Duty Engine Oils

Fleet SAE 30W

Fleet SAE 30W

Benefits of MAG 1 Fleet SAE 30 include:

  • High detergency and superior dispersancy keep engines clean and soot suspended in the oil despite longer drain intervals and increased soot loading
  • Exceptional resistance to thermal degradation, even under the most severe operating temperatures, prevents viscosity increase and the deposit formation and wear that can result
  • Superior anti-wear agents extend engine life despite high operating temperatures and extended service intervals
  • Higher starting TBN provides added protection against acid build-up that can cause rust and corrosion
  • Highly reliable performance over a wide range of temperatures, including severe cold
