Check the lubeguide

Nulon Mineral 20W-50 Super Diesel Engine Oil is formulated to provide the highest level of protection for old or worn diesel engines, large or small, non-turbocharged and turbocharged. It is ideally suited to vehicles that have travelled higher kilometres and require the added wear protection or oil loss prevention of a higher viscosity engine oil. Nulon Mineral 20W-50 Super Diesel Engine Oil can also be used in higher ambient temperatures or prolonged hot running conditions.

Meets the requirements of API CH-4/SJ

Nulon Mineral 20W-50 Super Diesel Engine Oil is ideal for older mixed fleet use for vehicles not requiring a Low SAPS oil.

Benefits

  • Formulated for older high kilometre diesel engines requiring extra protection
  • Thicker viscosity slows oil loss and burning in worn diesel engines
  • Greater engine protection for older diesel engines and high temperature conditions
  • Suitable for all, turbocharged and non-turbocharged diesel engines
  • Provides superior protection for LPG, CNG and dual-fuel system vehicles
  • Minimises sludge deposits to keep your engine cleaner
  • Superior deposit control reduces soot and prolongs engine life
  • Reduces oil consumption and the need for regular top-up
  • Ideal for older fleet use

Very hard to buy a diesel oil with a hot 50 weight rating. Tired one other brand and it just couldnt handle the extreme heat in an old tuned up diesel towing in summer, oil was a 30w in under 2000KLMS. I was able to pick up the NULON 20w-50 super diesel for a great price and i have been very very happy with it. Keeps its viscosity in high heat high load towing and helped keep the old high kilometer emgine nice and quiet. Im a hard guy to impress but non have done it with this product.

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.

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.

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.

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).
