Ok so just came back from the oil store where I buy Mobil 1 from. I looked at all his stock of Mobil 1 4L and it turns out all had golden caps. When I inquired he said he never kept silver caps and that the oil which was filled in my car also had a golden cap. I therefore must be mistaken in assuming that my Mobil 1 had a silver cap because
1)All his stock had golden cap
2)The 1L bottle I have also has a golden cap and in case (just assuming) the 4L bottle had silver cap I must have noticed it and cancelled the purchase because everytime I purchase, I carefully check the bottle, packaging etc to ensure its not counterfeit or repackaged etc and having bottles with different caps can not pass through my eyes
Also another interesting fact that he told me was that it is not possible to get Mobil 1 at 3600/4L, atleast not from authorized distributors, Mobil Askari Lubricants. He showed me official retail price of Rs. 4800/4L and his purchase cost receipts of Rs. 4100/4L. When I asked him how is it possible that it is available in the market at Rs. 3600/4L and at reputed workshops like Shahnawaz, the explanation he gave me was
1)Smuggled OR/AND
2)Drum mall repackaged in bottles
In any case, madz_freak, please post the back of your Mobil 1 including the serial number.

Although I do change oil at 5,000km along with oil filter at each change, Why do you say that these oils are not good for more than 5,000km? The shopkeeper I buy from insists I change at 10,000km and that by changing at 5,000km I am only wasting money
