Todays sophisticated European engines produce higher horsepower densities per cubic inch and topic the engines oil to severe operational conditions. Throw in all the emissions control equipment on these cars and the oils used should demonstrate exceptional anti-wear efficiency and meet the strict formulation requirements wanted to meet the most current European motor oil specifications.
Those specs at this writing are VW 504/00/507.00, VW, 502, 505 and 505.01, BMW LL-04, Porsche C-30, ACEA C-3, ACEA A3-B3/B4, Mercedes Benz 229.31 and 229.fifty one etc. Since most European car makers specify oil change intervals which can be considerable longer than those of U.S automotive makers, oils assembly these specifications need to demonstrate wonderful high temperature/high shear performance (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 handle the high operating 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 stay cool and lubricated
Because of the sophisticated and very efficient pollution control 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 harm fashionable exhaust treatment devices. Diesel particulate filters (DPF’s), for instance, require low-SAPS motor oil to help prevent filter plugging. This is why utilizing motor oil that does not meet the right 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 difficulty in producing a engine oil that both provides outstanding protection and meets the car makers necessities for use with their engine advanced pollution management equipment. Essentially the most superb 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 starvation and providing quick 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 a number of the biggest names in European cars equivalent to Mercedes and Porsche are factory full of artificial oil and plenty of require the usage of synthetic oil to keep up the vehicles warrantee.
