Premium Mineral 40-70 Extra Thick Oil (ET4070)

Nulon Premium Mineral 40-70 Extra Thick Engine Oil is a high viscosity, premium mineral engine oil formulated to provide the ultimate protection for engines used under severe conditions such as towing, racing or prolonged heavy use in hot climates.

Compared to lower viscosity oils, this high viscosity blend can reduce the signs of engine wear such as oil consumption, oil burning and blue/white exhaust smoke. This engine oil will also reduce the amount of oil loss past the piston rings making it suitable for old or worn engines.


  • Extreme protection for 6 and 8 cylinder performance and competition engines
  • Thicker viscosity keeps protecting even under heavy load
  • Provides maximum performance and oil loss prevention for worn engines
  • Maintains oil pressure and viscosity under severe conditions
  • Enhanced protection for vehicles using E10, LPG and Methanol fuels                  
  • Ensures maximum protection in race conditions
  • Reduces oil burning and the need to top-up
