  • 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.

    Rated 5 out of 5 by from Good product Car seemed to perform better after using this product. Only gripe is that there isn't a built in funnel so a spillage occurred on initial pouring. Well priced in comparison to other oils

    Rated 4 out of 5 by from Be careful when opening There's a metal foil which needs to be punctured/removed. Be careful when you do this that you don't tear it and have it end up in your engine. The quality of the oil: who knows? I went with a brand I knew. Fingers crossed!

    Rated 5 out of 5 by from Lovely product I've used standard oils in the past and they "do the job" this oil seems to do that job and more, the ticking from my old car has gone now ever since I've used this oil, and it runs like a dream, even for a 15 year old car!
