Always my first choice.
Always my 'Go to' oil. My engine seems to run smoother than some other brands and it's a premium quality oil at a reasonable price.

Castro may oil
Good oil at a good price, what's not to like. My wee car has now done 100k miles on this oil, changed every 6months, and needed no other maintenance. Sure Halfords, Tesco or Asda oil is cheaper but if you look about online you can get this for similar money, this 4lt tin was 26 quid, has cheap as any of the above. Roll on the next 100k

Always read the label
You have to remember that this is not suitable for diesel engines. It does state this on the bottle, but people never look on the packaging these days when buying Oil. Thats why you might see "good deals" around.
