About Diesel
Diesel is the dominant fuel in utes, 4WDs, light commercials, and most heavy vehicles. It uses a different combustion process to petrol — compression ignition rather than spark — and modern diesels run on Ultra-Low Sulphur Diesel (ULSD). Diesel does not follow the price cycle that petrol does, so its price tends to be steadier week-to-week. Per-litre price is typically a few cents higher than U91.
