Choosing the right engine oil to avoid damage to the aftertreatment system. Low or mid SAPS oils to reduce harmful exhaust emissions.
Catalytic converters are important components in a vehicle. In today’s world in particular, their importance in exhaust aftertreatment should not be underestimated. It is therefore essential to ensure that they are maintained and functionally maintained. Most catalytic converters are subject to a natural aging process with an average of approx. 80,000 to 100,000 km during their service life. However, due to additional loads, the engine control lamp in the cockpit can be displayed prematurely, which indicates a problem in the exhaust gas aftertreatment system.
For example, deposits containing stainless steel can be lost over time due to mechanical vibrations. Even short journeys can contribute to downright catalytic converter poisoning.
Burning too much oil in the engine is also disadvantageous. Despite the very low manufacturing tolerances of the components of an internal combustion engine and modern oil technologies, a small proportion of Engine oil always gets into the cylinder and burns there with the fuel-air mixture. Exhaust aftertreatment systems such as the diesel particulate filter (DPF), SCR catalytic converters and gasoline particulate filters (GPF) are overstressed as a result. The additives contained in the oil can be deposited on the surface of the catalyst and close the fine pores. The exhaust gases can no longer reach the precious metals and the catalytic converter loses its function. This reduces its effectiveness to the point of loss of emission reduction, which can also lead to a sharp drop in engine performance.
An important quality criterion in the development of new engine oils is the reduction of harmful exhaust emissions. Modern engine oils only consist of small amounts of sulphate ash (SA), phosphorus (P) and sulfur (S). These low or mid SAPS oils have a reduced ash content and are gentle on the exhaust gas cleaning systems. They ensure that the fine filter systems do not clog up so quickly and are an important contribution to environmental protection.
The easiest and most important way to avoid damage to the aftertreatment system is to choose the right engine oil. BIZOL engine oils have been developed for all vehicle types and the Technology line is specially designed for modern engines with modern exhaust gas aftertreatment systems.
With the Technology product line, BIZOL offers specially developed, state-of-the-art low and mid SAPS oils. In other words, engine oils with very low levels of sulphate ash (SA), phosphorus (P) and sulfur (S), which protect modern exhaust gas aftertreatment systems. In addition to excellent lubrication and long-lasting wear protection, the typical properties of BIZOL oils, these engine oils help reduce CO2 emissions and lower fuel consumption.
