About us

DIAMOND OILS GROUP is a professional oil blending company specializing in industrial, mining, farming and all racing engine oil applications.  

DIAMOND OILS consistently exceed industry standards, original equipment manufacturer's specifications and our customers expectations to deliver lubricants that achieve outstanding levels of protection and enhanced performance. 

DIAMOND OILS are based on virgin Group II Hydrocracked, Group III, Group IV and Group V Synthetic base oil, the most "shear stable", viscosity index improvers and the latest additives technology to hot blend components under agitation - in state of the art, stainless steel manufacturing facilities. Unlike many other brands, we do not use recycled oils in any of our products. "Hot blending" ensures the best possible bonding of all component ingredients in the manufacturing process, and the elimination of additive "dropout".

DIAMOND OILS also mix our extensive range of premium quality products by weight, not volume, ensuring industry-leading accuracy in production and optimum product specification, every time.
The end result is a better performing, longer lasting and more effective OIL for your vehicle, machinery or equipment.

Many oil manufacturers use recycled base oils and continue to "line" (or cold) blend their lubricants and mix by volume, which results in a poorer quality product that does not offer maximum component protection or perform as well, or last as long before needing replacement.

With a personalized approach for every customer, we will ensure you receive the highest quality lubricants and performance oils for your specific needs—whether it’s for passenger vehicles, heavy-duty machinery, industrial and farming equipment, or high-performance engines.

Protect your investments with premium Australian made quality oils, greases and lubricants and enjoy trouble free motoring for years to come.
