@all
very informative thread .. btw guys please only choose these engine oil grades (api SJ , api SL , api SM and latest api SN) .. rest api SE , api SF , api SG , api SH are all obsolete grades ..
also I would like to ask a question that if 4 litre api SN (10w-40) engine oil is not available then is it good or harmful if one use 3 litre api SN grade (10w-40) instead and mix it with 1 litre api SJ grade (10w-40) to make it 4 litre oil and put it in car ?
