Re: Is this the same Halford....
"If that's a reasonable price, you must be using some new definition of the word "reasonable". HINT: If you can't find the, equally as good, Castrol Edge for half the price, you're not trying."
From what I recall Castrol's retail oils are only available in 4 litre cans, as opposed to the 5 litre cans that everyone else sells for about the same price. The only way I can get 5ltr Castrol Magnatec 5w-30 for my Ford is to order it online from a dealer (Vospers parts, they do great value service kits)
