It originally started out as a horse-drawn cart company and has grown into one of the largest bus fleets in South Africa.

Passenger vehicles and motorcycles or heavy-duty industrial equipment, Havoline and Delo customers worldwide rely on our lubricants to keep their vehicles at peak performance.

Golden Arrow has a long relationship with Caltex and they are currently running their whole fleet on Delo® Gold Ultra engine oil and Delo® XLC coolant. Recently, Caltex and Golden Arrow personnel agreed to conduct an engine teardown and inspection on one of their MAN engines that had over 600,000 kilometres in severe service operation to see how the Delo® family of products has protected the engine parts.
The initial inspection overall showed a clean engine with minimal deposits and no visible sludge on the engine top deck and oil pan. As the engines components were removed, they were inspected to check on their condition.
Delo® XLC Extended Life Coolant also helps protect the engine cooling system on this bus. Inspection of the cooling system revealed that Delo® XLC prevented cavitation pitting on the liners and water pump impeller. The engine cooling system showed no signs of deposit build-up or corrosion on key metal parts. Additionally, the outsides of the piston liners are in very good condition with no visual sign of pitting or corrosion.
