Castrol Magnatec 10W40 A3 B4 Oil 4 Litre
Castrol Magnatec 10W40 A3 B4 Oil
The Castrol Magnatec 10W40 A3 B4 Oil clings to the engines surface like a magnet providing constant protection even when the engine is switched off, providing critical engine protection during start and warm-up periods.
Every time you start your car it takes most oils 10 minutes to work effectively, because the oil cannot protect properly until it reaches a critical temperature. Castrol GTX Magnatec 10W40 is different as it gets to work straight away by virtue of a unique synthetic ester that clings to the engine like a magnet.

The below is my opinion only!
I would not use Slick 50! It contains PTFE which is a solid. It's basically the same stuff that is used to coat non stick pans. PTFE has it's benefits but not in engines! It can eventually break down and cause blockages in oil ways and filters. NASA's research lab conducted their own test into this type of additive and concluded it can be detrimental to an engine. Don't just take my word for it, Google 'Slick 50 tests' and get all the facts.
I have personally used Extralube ZX1 Micro Oil Treatment previously in a few of my cars. It contains no solids and has been independently tested by laboratories and race teams around the world and also carries a NATO stock number. I noticed it made a difference to the noise and running of the engine (much quieter and smoother).
Both Slick 50 and Extralube ZX1 Micro Oil Treatment are available from Halfords.
