Народ, ну вы вааще жжоте!!!

Про оригинал/не оригинал - отдельная песня. Оргинал под номером GVW 052 195 M2 - это Кастрол в больших 208 литровых бочках

Про то, что такое Кастрол, и что у них одно м/р нефти - я вааще валялся. Кастрол это дочерняя компании BP. Это так к слову, про месторождения.

Про синтетику/минералку - еще один отжыг!!! писать долго - дам ссылку английский текст:

Цитата:
Mineral oil
This term is used to encompass lubricating base oil derived from crude oil. The American Petroleum Institute (API) designates several types of lubricant base oil identified as:

Group I – Saturates <90% and/or sulfur >0.03%, and Society of Automotive Engineers (SAE) viscosity index (VI) of 80 to 120
Manufactured by solvent extraction, solvent or catalytic dewaxing, and hydro-finishing processes. Common Group I base oil are 150SN (solvent neutral), 500SN, and 150BS (brightstok)
Group II – Saturates over 90% and sulfur under 0.03%, and SAE viscosity index of 80 to 120
Manufactured by hydrocracking and solvent or catalytic dewaxing processes. Group II base oil has superior anti-oxidation properties since virtually all hydrocarbon molecules are saturated. It has water-white color.
Group III – Saturates > 90%, sulfur <0.03%, and SAE viscosity index over 120
Manufactured by special processes such as isohydromerization. Can be manufactured from base oil or slax wax from dewaxing process.
Group IV – Polyalphaolefins (PAO)
Group V – All others not included above
Such as naphthenics, PAG, esters, etc.

In North America, Groups III, IV and V are now described as synthetic lubricants, with group III frequently described as synthesised hydrocarbons, or SHCs. In Europe, only Groups IV and V may be classed as synthetics.
The lubricant industry commonly extends this group terminology to include:

Group I+ with a Viscosity Index of 103–108
Group II+ with a Viscosity Index of 113–119
Group III+ with a Viscosity Index of at least 140
Can also be classified into three categories depending on the prevailing compositions:

Paraffinic
Naphthenic
Aromatic
While lubricants for use in internal combustion engines may solely consist of one of the above-mentioned oil groups, it is not desirable in practice. Additives to reduce oxidation and improve lubrication are added to the final product. The main constituent of such lubricant product is called the base oil, base stock. While it is advantageous to have a high-grade base oil in a lubricant, proper selection of the lubricant additives is equally as important. Thus some poorly selected formulation of PAO lubricant may not last as long as more expensive formulation of Group III+ lubricant.
