Concerns have been raised over a shipment of Premium Motor Spirit (PMS) in Kenya that may not meet national fuel standards, prompting investigations into potential regulatory waivers and corruption.

• The primary issue is the potential use of off-spec fuel, which deviates from required chemical and safety standards for petrol and diesel.
• Key figures involved include former Petroleum Principal Secretary Mohamed Liban and the Trade Ministry.
• Investigators are examining waivers granted for components like oxygenates, manganese, sulphur, and benzene, which could compromise vehicle performance and longevity.
