Hi all.

I came across this workshop whereby they promote this OSK Engine Oil (Be it fully/semi/mineral oil)
Anyone heard of this brand before?
Before this I use castrol from their workshop but my friend say a lot castrol are fake nowadays and I don't know how to verify it.
But usually a lot of locals nearby go there to service their cars so I think quite trusted/reasonable.
OSK Engine Oil review??

Never heard of that brand before.
If you think your regular workshop is trusty enough then just continue there buying from them. But if I were you, for Castrol I'll just buy from Tesco/AEON coz would be much cheaper when on promotion.

Recently just saw a receipt from P2 Sc quoted OSK P8500 (semi) 4L at RM118.
It has got api donut logo and yes it is indeed listed in api website.
