Todays sophisticated European engines produce higher horsepower densities per cubic inch and subject the engines oil to severe operational conditions. Throw in all of the emissions management equipment on these automobiles and the oils used should demonstrate exceptional anti-wear efficiency and meet the strict formulation necessities needed to fulfill essentially the most present European motor oil specifications.
These specifications at this writing are VW 504/00/507.00, VW, 502, 505 and 505.01, BMW LL-04, Porsche C-30, ACEA C-three, ACEA A3-B3/B4, Mercedes Benz 229.31 and 229.fifty one etc. Since most European automotive makers specify oil change intervals that are considerable longer than these of U.S car makers, oils meeting these specifications have to demonstrate wonderful high temperature/high shear efficiency (HT/HS) to take care of viscosity and provide adequate engine protection.
In addition, turbocharged direct injection (TDI) engines are frequent in European vehicles. Motor oils utilized in these applications have to be very thermally stable to deal with the high working temperatures and resist deposit formation while providing adequate turbocharger cooling. Thermally stable oils assist keep oil passages clean and promote fluid circulation so turbocharger bearings keep cool and lubricated
Because of the sophisticated and extremely efficient air pollution management equipment used on European vehicles, virtually all European automotive makers require oil utilized in these applications to be formulated with decrease quantities of sulphated ash, phosphorous and sulfur. (SAPS) SAPS is a commonly used anti-wear additive in motor oils.
The problem is that oils with excessive sulphated ash, phosphorus and sulfur (SAPS) can hurt modern exhaust remedy devices. Diesel particulate filters (DPF’s), for example, require low-SAPS motor oil to assist stop filter plugging. This is why utilizing motor oil that doesn’t meet the correct specification can cause engine problems and that annoying check engine light to come on!
Because SAPS additives provide a high degree of wear protection, its reduction has caused some motor oil formulators considerable issue in producing a engine oil that both provides outstanding protection and meets the automobile makers requirements for use with their engine advanced air pollution management equipment. Essentially the most ideally suited motor oil for European engine is high grade artificial oils engineered for the above specifications. Synthetic oils have very low pour factors protecting the engine from oil hunger and providing immediate oil pressure when the outside temperature is low while its thermal stability withstands high-temperature/high-RPM breakdown to withstand deposit formations that starve TDI systems of lubrication.
This is why some of the biggest names in European automobiles such as Mercedes and Porsche are factory filled with synthetic oil and lots of require the use of synthetic oil to keep up the cars warrantee.
