Hi,
I saw that costco were selling big drums of oil for about £40. I can't remember the brand, sorry, nor the size: I think they were 20L or may be 25L. There was a 5w-30 for petrol and 10w-40 for diesels.
Does anyone know whether these are good? The price seemed nice, though being costco it would of course be ex vat.
TIA
