If currency note can be forged, I doubt the seal would stop the selling of fake oil, if that's your concern.
In fact how original in Castrol Malaysia anyway? If u frequent online, u will see Castrol Oil sold elsewhere in the world, more so in Europe is very different in packing. So who's is original? or is there an "Original" original?
While the above suggestion is good, I would always, and only buy my oil from known source and if that is not enough, customer can always contact Castrol Malaysia to identify the dealer nearest to your place... that's way, even no seal oso you don't have to worry..
What I don't like about Castrol is their LL-04 grade Valvetronic complaint engine oil only comes in bulk pack in Malaysia and to be sold to workshops and Service Centers. Meaning we Valvetronic owner is either their Castrol's workshops' customer, or not their customer..
They put up a counter in our recent Mini Bimmerfest, u go in talk to them to ask for recommendation of oil for E90, they just smiled and shake their heads. I almost wanted to ask why are they there...
I may sounded a little sarcastic but I don't mean to ask them to stop supporting our club.. I just hope they can bring in engine oil of the Valvetronic BMW-LL04 grade so we can support them. Seriously, your only competitor is Torco, which is the only consumer pack engine oil with SM LL-04 grade we can get from shelves for DIY oil change, in Malaysia.
Just my 2 sen..
... and not forgetting to thank them for the generous sponsors of our new member starter pack of engine oils. Great stuff for my Toyota! :top:
