Ajde onda, objasni nam, sto oznacava ta oznaka?
TAKUMI
Objasni nam ovo za oznake.
Uz to, da li je ista gustina ulja 0W i 20W?

Ne zamaraj ljude i zbunjujes ih oko ulja znas dobro engleski pa si najpametniji od svih, a ovu temu smo prije godinu dana dobro raspravljali stim da sam ti davao odgovore na koje si ti komentarisao svasta.

0W ide vise u uslovime zime u minusu nego 20W, ide cak do -45 stepeni.
sada ces ti dati svoju verziju kod hladnog starta
Znaci, 0W i 20W imaju isti gustinu kad je motor hladan?

Svako ulje ima tacku stinjavanja i tacku paljenja to su krajnje granice ulja, klempo.
Ne seri, nego odgovori na pitanja.

normalno ako mu je broj manji prije W da je ulje redje i stim moze vise da izdrzi u minusu, a da ne zaboravim da oznaka W oznacava WINTER- ZIMA uslovi koje pravi zima ili niska temperatura.
druga cifra posle W,znaci viskozitet ulja kad je motor vruc(kad je dostigao normalnu temperaturu)

The Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating their "winter" (not "weight") or cold-start viscosity, at lower temperature. The number 20 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade. The document SAE J300 defines the viscometrics related to these grades.
Kinematic viscosity is graded by measuring the time it takes for a standard amount of oil to flow through a standard orifice, at standard temperatures. The longer it takes, the higher the viscosity and thus higher SAE code.
Note that the SAE has a separate viscosity rating system for gear, axle, and manual transmission oils, SAE J306, which should not be confused with engine oil viscosity. The higher numbers of a gear oil (eg 75W-140) do not mean that it has higher viscosity than an engine oil.
