Mining and Off-Road

Gulf itself has first-hand experience of quarrying, tunnelling and large earth moving operations through its own mining contract services company.

This has facilitated Gulf Oil to assemble a range of lubricants and other fluids ideal, both technically and commercially, for use in construction and off-highway equipment, such as mechanical excavators, cranes and heavy trucks. These machines often operate is very arduous conditions, with exposure to heat, dirt and water, which only the most robust lubricants and greases can withstand. The Gulf products have been thoroughly tested in this equipment and are offered to you with our fullest confidence.

There are engine oils, some with high additive content to handle the corrosive by-products from the combustion of poor quality fuels as well as transmission oils and greases.

Additionally, Gulf offers some products ideally suited to this harsh working environment. Products such as Gulf Rock Drill Oil, for pneumatic tools, and greases/open gear lubricants for wire ropes, gear trains and open bearings on heavy machinery and hoists.

Finally, most modern construction involves concrete. Gulf has a range of mould release compounds for application when pouring concrete. These facilitate the removal of steel and wooden mould panels without damage to the concrete surface.

You can learn more about these oils through our unique Gulf Product Search tool on this web site.
