LUBRICANTS IS A SUBSTANCE WHICH IS USED TO CONTROL FRICTION AND WEAR OF SURFACES IN CONTACT OF THE BODIES.
TECHNICAL INFORMATION
GROUP1:- FEATURES OF GROUP 1 BASE OIL: SATURATION DEGREE IS BELOW 90% SULFUR IS OVER 0.03% AND VISCOSITY INDEX IS FROM 80 TO 100. THIS BASE OIL IS PRODUCED THROUGH SIMPLE REFINEMENT OF SOLVENT AND IT IS CHEAPEST ONE AMONG OTHER BASE OIL.
GROUP 2:- Features of group2 base oil: saturation degree is over 90%, sulfur is below 0.03% , and viscosity index is from 100 to 120. this base oil is produced through decomposition of hydrogen which is more complicated process than group1 base oil has more transparent colour than group 1 base oil but it is not expensive. that is why group 2 base oil is popular in usage.
GROUP 3:- Features of group3 base oil: saturation degree is over 90%, sulfur is below 0.03%, and viscosity index is over 120. group3 base oil is produced through more refinement and severe decomposition of hydrogen process with higher temperature and pressure than group 2 base oil. even through group 3 base oil is produce from crude oil , it is sometimes called as synthetic base oil. group 3 base oil is popular in usage like group2.
