you sure you are buying original mobil 1 made in singapore and not mobil 1 form MAL pakistan?, cause the packing remains same, all of my cars use mobil 1 mostly 0W-40 though, i had bought 5W-50 just two months ago, only packing of 0W-40 has changed and now it has a small formula 1 at the bottom, 0W-40 is for 5500rs maybe you got told of them,
as a alternate i use Repsol, its 5W-40 SN and has a lot of approvals like mobil 1 has including Porsche and its was 4400rs.
