If a lubricant needs to be replaced or topped-up, then in many situations the most readily available lubricant is used, whether it is the right oil for the application or not Attempting to estimate the commercial vehicle parc is no easy task because clear and reliable data can be difficult to confirm. However, conservative estimates suggest that the commercial vehicle parc in Africa is in the region of 5,000,000 to 10,000,000 vehicles. This creates a total African vehicle parc in the region of 25,000,000 to 30,000,000 vehicles – yet little is understood of this business or industry outside of Africa. With so many vehicles in use in Africa, and all global vehicle manufacturers actively being represented (including North American, European and Asian manufacturers), the vehicle types and technologies are becoming more varied and diverse, which requires a broader understanding of modern vehicle maintenance and service requirements. Larger African cities have the luxury of having ‘Manufacturers’ Service Centres ‘and ’approved workshops’ along with training centres and specialist support to ensure that Septmber 2015 • | Lubezine Magazine vehicles receive the most appropriate care and maintenance. However, because of the sheer size and geography of Africa, many African vehicle owners in certain regions are unable to access the OEM-approved service centres in larger cities, these vehicles may never receive the dedicated support and preventative maintenance that is required for reliable operation for years into the future. For these vehicle owners, often the only time lubricating oil is changed is after a component failure. Typically, repair work is completed using outdated methods and operating practices which cannot provide adequate support and protection to modern vehicle technology and component designs. The preventative maintenance model is a foreign concept to many vehicle owners even in parts of the developed world and it’s unfamiliar to wide portions of the emerging markets. Yet, this preventative maintenance model is arguably most important to the remotest parts of Africa where vehicles are an important lifeline for communities. Preventative maintenance and routine servicing is far from reality for many community and individually owned vehicles, especially where unadditised oil or previously used oil is the standard replacement fluid when repair work is carried out. These vehicles may have never been driven on a tarmac surface and are often overloaded. Operators use lower quality fuel than they were designed to run on and the vehicles experience harsh conditions over severe terrain, without access to proper service. Repair work can be creative and imaginative, as technicians use any means necessary so that the vehicles can continue to be used for another day. If a lubricant needs to be replaced or toppedup, then in many situations the most readily available lubricant is used, whether it is the right oil for the application or not. An inappropriate lubricant can usually provide some component protection for a period of time, but there is a huge risk. Without the proper lubricant, failure is inevitable; however, the use of an incorrect lubricant may not be identified as the cause of the problem, so the cycle continues and incorrect oil may continue to be used again and again, causing further damage. With numerous global powerhouses of the lubricant industry already established across Africa, knowledge and understanding of automotive lubricant requirements is increasing outside of larger cities, yet the sheer scale and infrastructure of the African continent makes this task impossible to complete as quickly as ideally required. Much of the lubricating oil used in some African regions is either unadditised or formulated with minimal additives that cannot provide many of the performance attributes of a lubricating fluid. Without proper additives, the oil will be more prone to degradation through deposits and sludge formation, which can overheat the oil and an increase its acidity. The level of protection provided by unadditised or poorly additised oil is constantly decreasing as technology and equipment design progresses and the requirements of the lubricating fluid are further and further increased. At one time, basic oils may have provided some level of component protection and performance, but that time has passed. Today’s vehicles have a far higher requirement of the lubricating fluid, based on increasing power densities, the wider variety of materials used in engines, and complex transmission and axle component. Automotive developments and advancement over the past 75 years have seen the introduction of higher power and torque being
