Jos uvek niko da se baci na prevodjenje , jer ovako opet ostaje nedoreceno.
Ajde nek neko baci prevode oznaka na uljima, ACEA A2/B2/E2, API SH/CD,CCMC... ne mogu da pronadjem gde su mi , a mislim da ce mnoge zanimati.
Pa to su standardi, ne moze da se objasni u dve reci

Klasifikacija Društva automobilskih inženjera (Society of Automotive Engineers - SAE) - klasifikuje ulja prema njihovoj viskoznosti. Motorna ulja mogu biti monogradna ili multigradna, u zavisnosti od njihovih viskoznih karakteristika na različitim temperaturama.Originalno postavljeno od SALE
Klasifikacija Američkog instituta za naftu (American Petroleum Institute - API) - motorna ulja klasifikuje prema njihovoj sposobnosti da zaštite motor. Slovo S u oznaci obeležava motorna ulja namenjena benzinskim motorima, a slovo C motorna ulja za dizel motore. Naredno slovo u oznaci označava nivo kvaliteta i zaštitu, koji se obeležavaju slovima od A za najnižu do X za najvišu. Neka ulja mogu da se koriste i u benzinskim i u dizel motorima, pa je njihova kvalifikacija SJ/CF ili CF-4/SJ.
Klasifikacija Asocijacije evropskih proizvođača vozila (Association des Constructeurs Europeens d'Automobiles - ACEA) - ova klasifikacija je veoma slična API klasifikaciji, sa tom razlikom da se API oslanja na testove na američkim, a ACEA na evropskim motorima. ACEA takođe koristi slova za obeležavanje klasifikacija.
