Today I also opted open/Big drum oil as did last month.
They told me to change at 3, 000 Km but I changed them at 3,500 Km but to my surprise, oil was full and this time, no more oil leaks from o rings or plugs or any of oil/engine seals.
It costed total 1790 in following:
Guard Oil filter: Rs. 240
Guard Air filter : Rs. 500
Oil X/D 20/50: Rs. 1050 for 3. 5 Litre @Rs. 300 per Litre
@tintin1 This time, drum was not labelled as Orient Lubricants and also 20/50 is mentioned. Is it typographic mistake of 20w/50 or intentionally 20/50 for some other standard of Single/Multi grade oil.
There was also X/D 50 but he told it is for weaker engine and unigrade (single grade).. It was 250 per Litre
