i know this is an old topic, i saw one comment above of this member using tesco engine oil and found no problems with it.

as for homebrand tesco stuff, undeniably it is of lower quality. especially when it says tesco value. HOWEVER, the homebrand stuff sold in UK (made in UK/EU) tesco branded things are actually good, comparable with good brands and value for money.

even in australia, their coles/woolworths homebrand stuffs are actually okay and not lousy as our own home brand.

So in summary, its a malaysian problem. they sell homebrand, but sell lousy stuff.
