The key norms & what they mean:

API - American Petrol Institute
Used since approx. 1941. The S-classification refers to combustion engines & the second letter denotes the quality. From 1980 standard SF applied, from 88 SG, from 93 SH, & from 96 SJ. The addition of "/ CF" denotes that the oil has been tested using high performance reference engines. The API classification for 2 stroke engines is no longer in common use.

ACEA - European engine oil classification
Valid since 1996, classes A1-A3 denote oils for petrol engines, B1-B4 those for diesel engines. Higher numbers denote better test performance.

JASO - Japanese engine oil classification
The Jaso T 903 is currently the most important classification for 4 stroke engine oils, which covers performance within the main engine parts but also auxiliary areas such as the clutch. Suffixes MA & MB inform on slip resistance, whereby MA provides a higher slip resistance factor.

Viscosity (SAE)
This norm describes the range of temperatures in which the engine oil will perform. In general, the smaller the integer with the W (Winter), the better the oil will continue to flow in cold temperatures. The larger the number without a letter, the better the oil will maintain lubrication in high temperature situations.Safety Notices
