Premium Mineral 40-70 Extra Thick Oil

Premium Mineral 40-70 Extra Thick Oil

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

Is synthetic oil better than mineral oil?

4 years ago

Synthetic base oils have a number of advantages over mineral base oils. The uniformity of the synthetic oil molecules improves the thermal stability and reduces oxidation of the oil. Controlled molecular structure also results in lower volatility and a more stable vicosity over the life of the oil.

Can I use a diesel engine oil in a petrol engine and vise versa ?

4 years ago

Most diesel engine oils carry a higher specification rating than petrol engine oils and vehicle manufacturers often specify a diesel engine oil be used in a petrol motor. This does not work in the reverse, petrol only engine oils cannot be used in diesels. Some engine oils carry both petrol and diesel specifications.

My engine oil discolours quickly, is that a problem?

4 years ago

All engine oils contain detergent and dispersant additives which remove contaminant build-up inside your engine. When new oil is added to an engine these additives strip away build-up and hold the contaminant in suspension so it can be removed when the oil is drained, this does discolour the oil.

What does SAE, API, ACEA stand for?

4 years ago

SAE is the Society Of Automotive Engineers (USA). The SAE rating of an oil is a measure of its viscosity (eg 20W50).

API is the American Petroleum Institute. The API rating of an engine oil covers the performance rating of the oil (e.g. SM for petrol, CF for diesel).

ACEA is a European industry body up of European vehicle manufacturers. The ACEA rating of an engine oil of covers the performance rating of the oil (e.g. A3/B3, C3).
