فالفولين ليها موقع استرالى و الموقع الاوروبى
نفس اسم الزيت بتختلف مواصفته اختلاف كبير بين الموقعين .. الموقع الاوروبى مواصفته اعلى .. و ده لاحظته لما كنت بادور على Engine Armour زمان
بالنسبه ل Synpower .. بيكون منه نوعين لنفس اللزوجه .. احدهم بيكون فيه كلمه MST
MST stands for Mid SAPs Technology
ال MST بتكون للتوافق مع المواصفات الاوروبيه Euro IV and Euro V و بتكون زيوت Long drain فى المعتاد .. و ايضا للتوافق مع بعض المتطلبات الخاصه بمواصفه لزيت خصوصا لمحركات ديزل معينه
European Motor Oils and SAPS Content
What is SAPS?
SAPS stands for sulfated ash, phosphorus and sulfur. They comprise a significant portion of a motor oil’s additive content. Sulfated ash is not added to oil;
it is the result of additives in the oil burning and creating ash. The
additives that can produce ash are most commonly
used for total base number (TBN), but also help in other areas, like
antioxidancy, anti-wear,
cleanliness and soot handling.
Phosphorus provides anti-wear properties and further
antioxidancy, while
sulfur contributes antioxidancy, anti-wear properties and engine cleanliness.
SAPS Levels
Given the beneficial properties these additives impart, it’s easy to assume a higher concentration equals a better oil.
But higher SAPS levels can be a detriment to expensive exhaust devices, such as diesel particulate filters (DPFs) and catalysts. The European Automobile Manufacturers’ Association (ACEA) and original equipment manufacturers (OEMs) realized the importance of using motor oil formulated with precise SAPS levels, and lower limits were established in 2010.
The three different SAPS levels of European motor oils can be confusing, especially when considering the same viscosity motor oil (5W-40) is available in mid- and full-SAPS AMSOIL European Car Formula options
واللى فهمته من قراءه سريعه ( قد لا تكون دقيقه لان الرابط قديم ) .. ان النوع ال MST مبيكونش متوافق مع ILSAC .. يعنى موش حيكون مناسب لشيفروليه
It is not ILSAC GF-4 approved primarily because of the highly shear stable VM and high HTHS requirements. This does not make it able to pass the Seq VIB fuel economy test.
