Yes, you can change to a different viscosity according to commercial vehicle usage, environmental and climatic conditions.
No. Look instead for a reputable brand like Mobil Delvac, for a product that meets specifications set by industry and original equipment manufacturers and buy products you know to be authentic from a trusted supplier.

Because they flow better at low temperatures, it’s possible to manufacture thinner synthetic oils and it’s these low viscosity oils that modern engines need to help reduce fuel consumption and emissions.

Synthetic oils also have a higher film strength, which gives better protection and reduced wear. And, as they are more stable and less volatile at high temperatures, they work better for longer, effectively reducing the engine’s oil consumption.

Viscosity is a measure of thickness. At low and high temperatures, the viscosity of oil is measured on a scale determined by the Society of Automotive Engineers and given an SAE number to indicate this – so an SAE 30 will be thinner than an SAE 40 oil.
