saw some funny comments from noob...

anyway.. if the bottle is sealed, it can be kept up to 4 years.

FYI, Tesco imported the bottles from EU, hence no seal, this is because they don't

have fake oil issues like here in poor country.

And i can tell you, even with seal, the oil selling here locally also might no be genuine.

Used Mobil1 fully sync from Tesco before 0W40, no issues at all.

That time was RM129, i bought 2 bottles.
