Simply great
Oil is oil, right? I don't believe so. How can I tell what's really happening in the engine? Well, I suppose I can't, but the old engine is running well and the fuel economy has jumped too, which surprised me given I've tracked my economy for many years and it's never been this good! Decent value when bought in a large container.

Superlative quality products.
I have used Castrol oils since the mid 1960's including Castrol R in my performance engine'd vehicles. Castrol was the oil of choice throughout my 50 years in the Motor trade, I used the correct recommended Castrol oil in my Dreaded Eco boost engine with absolutely no problems. I can absolutely recommend Castrol oils .

Does the job but a little restrictive
A cheaper alternative to the Genuine OEM oil recommended for my 2007 Fiat Panda 1.1 Active (Euro5). I have since replaced this with Mobil super 2000 X1 which I have feel lets the engine rev up easier than the Magnatec does.

Olio semisintetico di alta qualità, il Castrol Magnatec 10W-40 è un punto di riferimento per motori che richiedono questa specifica viscosità. La tecnologia delle molecole attive che aderiscono alle parti metalliche del motore anche a veicolo spento è percepibile durante gli avviamenti a freddo, che risultano più fluidi e meno rumorosi. Sotto stress termico, l'olio mantiene una stabilità chimica ottimale, riducendo la formazione di depositi e morchie. Il formato da 4 litri è ideale per un cambio d'olio standard sulla maggior parte delle utilitarie e berline medie. Una scelta di sicurezza per chi vuole prolungare la vita utile del propulsore riducendo l'attrito meccanico nelle fasi critiche.
