If the number of soot particles in the oil increases due to faults in the injection system or as a result of incorrect valve control, the additives will no longer be able to keep all of the particles in check. This often leads to an increased burden on the exhaust treatment systems. Even if the exhaust valves open while there is still oil on the wall of the cylinder, partly unburned oil can escape through the exhaust system. If internal leaks occur, oil can come into contact with fuel in the engine‘s combustion chamber. Moving parts of an injection system are partly lubricated via the engine‘s oil circuit. In extreme usage conditions, an analysis of the used oil can show that the intervals should be reduced.įaults in the injection system or valve control If oil analyses are not carried out, the oil change intervals stated by the manufacturer or those indicated by the on-board computer should generally be adhered to. Their function is reduced and there is a threat of damage and significantly shorter service lives. Engines of generations Euro V and VI with their complicated exhaust gas treatment systems are particularly affected. If engine oils are used which are not freely shared, the limit values for exhaust emissions can often not be complied with. with regard to loss due to evaporation, there is a risk of increased oil consumption. If the specific requirements are not adhered to, e.g.
It is not without good reason that automobile manufacturers include the ACEA or API specifications of the oils in their operating manuals, or freely share their names. As a result, the oil temperature increases. But if too much oil is used, increased splashing and therefore more flexing work is the result. Oil level in the engine which is too highįor quantities of oil which are too great or if there is too much fuel in the oil due to constant short trips, the crankshaft will dip into the oil sump.
OIL CONSUMPTION FULL
Full throttle, use which is predominantly of a „stop and go“ nature, or demanding hill ascents cause temperatures and therefore loss due to evaporation to rise.
