Diesel Myths That Won’t Die

Myth: You cannot use on-road diesel fuel in off-highway engines

Truth: In modern markets, the fuels themselves are essentially the same

In Australia, both on-road and off-road diesels are Ultra-Low Sulphur Diesel, meeting the same baseline fuel specifications.

The difference lies in taxation and the presence of dye for compliance with fuel tax laws, not the chemistry required by the engine itself. As such, from an engine performance standpoint, using one over the other does not harm the engine. It simply affects operating cost due to excise treatment.

Environmental & Emerging Tech

Myth: Off-highway diesels are unregulated and dirty

Truth: Modern emissions control has made huge gains

Today's engines, across many industrial applications, deploy advanced after-treatment like Diesel Particulate Diffusers (DPD), oxidation catalysts and SCR systems that cut particulate and NOx emissions dramatically compared with older designs.

These systems make off-highway diesels markedly cleaner and more environmentally responsible than stereotypes suggest.

In applications where environmental performance matters, such as near communities, agricultural zones or built-up sites, modern technology makes diesel a far cleaner option than legacy machines.
