Any Castrol oil is worth buying from any store, so oils
I bought this product ,as having been in the industry it has a Good reputation.
ITS GOOD OIL, My car I have found runs smooth to drive.
Works well in my 95 EF falcon, I only need it for the occasional top it..
Was easy to find and staff were friendly and no issues applying the discount on my account
I bought this cause dads çar needed some oil in it and it actually filled it up.aha
