DECEMBER/JANUARY 2021 AFTERMARKET 43 contains solvent-free Powerful Cleaning Agent (PCA) additive technology, delivering a deep yet gentle clean. “Despite its comprehensive cleaning ability, Castrol Engine Shampoo doesn’t have any of the harmful side- effects of a solvent-based engine cleaner.” On usage, Gareth added: “One bottle of Engine shampoo is effective for vehicles that use 3L to 6L of engine oil. It is recommended for use at every other oil change, mainly for older and high mileage vehicles. However, it can also be used for new vehicles as a preventative measure.” “Engine Shampoo helps to maintain engine power and efficiency by dissolving and flushing out sludge during the oil change process. The application takes ten minutes prior to servicing and can happen anywhere that the car can be safely parked. After the engine has warmed the oil, it is switched off and 300ml of Engine Shampoo is added. The engine is then switched back on and left idle for 10 minutes. The sludge transfers to the engine oil, which is then drained with the engine off, and the filters are replaced. This process maximises the cleanliness of the engine internals, ensuring the new engine oil can perform at optimal levels.” Additional You need to consider all the vehicle segments out there when thinking additives. “There are now growing numbers of hybrid vehicles on the road,” said David Kaiser, Head of Research and Development at LIQUI MOLY. “For garages that don’t specialise in electric drives, this opens up opportunities for additional business. After all, hybrid vehicles face a whole new set of problems.” This especially concerns cars that often only cover short distances, so they mostly run on electric power: “In this case, the fuel stays in the tank for longer and undergoes a more marked ageing process,” said David. “In addition, also due to irregular short-term use, there can be residue in the injection tract. Here, the engine no longer runs as smoothly and emission levels deteriorate. This also affects the service life of the injectors. “LIQUI MOLY's Hybrid Additive helps here. It keeps the fuel quality stable, provides protection from deposits in the injection system and removes any residues. Here you can kill two birds with one stone. The petrol additive is well suited to use by the garage and for selling to car owners. “Frequent cold starts and brief periods of use of the combustion engine also causes problems elsewhere in hybrid vehicles: condensation and fuel residues accumulate in the oil circuit. In a pure combustion engine this is not an issue, because as soon as the engine oil has reached its operating temperature, the water and petrol vaporise in the oil. In hybrid vehicles, the engine oil rarely reaches the operating temperature, so more water and petrol can accumulate in the oil circuit. This increases wear and tear – and it is conducive to corrosion, too.” Important It’s important not just to change the oil but also to thoroughly clean the oil circuit at the same time. “This can be done using LIQUI MOLY Engine Flush,” said David. “Just before changing the oil, the additive is added to the engine oil and the engine is then run at idling speed for ten minutes. During this time the active ingredients remove any deposits and debris, which is then simply drained out together with the used oil. The fresh oil then goes into a clean engine, so it can achieve maximum performance.” There is another problem caused by frequent cold starts in hybrid vehicles: on each occasion, it takes several seconds for the oil to reach every part of the engine, depending on the ambient temperature. “Until that happens,” pointed out David, “metal rubs against metal – pure wear and tear. In the case of pure combustion engines, cold starts are not much of a factor overall. The situation with hybrid vehicles is very different: Here it is a good idea to add LIQUI MOLY Cera Tec to the oil. This is a wear- and-tear protection additive that provides dual protection for the engine. Firstly, there is physical protection by means of tiny ceramic particles that spread out on the metal surfaces to prevent direct metal-to-metal contact. Secondly, chemical protection is provided by so-called friction modifiers which smooth the metal surfaces and prevent friction. The use of Cera Tec significantly reduces wear and tear during the cold start phase.” David concluded: “By applying these LIQUI MOLY products, garages can offer their customers attractive additional services that are also easily understood by non- experts. And these are just a few examples of how tailor-made service packages can be compiled with LIQUI MOLY.” Fuel and engine additives can form an important additional income stream... ” % $ " $ !" #$ %& GDI Injector % #% $ # $% Cleaner % $ $ % " $ % # " $ $ # # Email: info@kalimex.co Call: 0 800 783 3717 For more information: % . uk
