Reliable Oil from a Trusted Brand
I’ve been using Castrol MAGNATEC for regular maintenance, and it performs as expected from a well-known brand. The engine runs smoothly, with quieter operation noticeable after the oil change. Cold starts feel more responsive, and the oil maintains good consistency over time. Overall, it’s a reliable choice for everyday driving and routine servicing and great value for money.

Oily oil
I've been using Castrol oil for my Peugeot 208 petrol for quite some time now, and I must say, it has significantly improved my vehicle's performance. One of the standout benefits I've noticed is that my engine uses less oil and I need to top up less frequently, which is a huge plus for me with mileage on clock closing to 100k miles. The packaging is clear and the instructions are straightforward, making it easy to understand how much oil is needed and when to change it. However, I do have one minor gripe – the design of the canister. It's a bit difficult to pour the oil without spilling some on the engine, which can be a bit messy and inconvenient. It's relevant more when canister is full and much easier to pour when it's half used. Pull out type spout would be very handy here. Despite this small issue, the overall performance and benefits of this oil far outweigh the inconvenience of the can design. My engine runs smoother and more efficiently. If you're looking for a reliable engine oil that improves performance and reduces the need for frequent top-ups, I highly recommend giving Castrol a try. Just be prepared for a bit of a challenge when it comes to pouring it!

Happy customer here, highly recommend it
I replaced the engine oil myself this time and feel much more satisfied than when I relied on garages. The oil quality is great, and the container is sturdy and convenient for any future use. I’ll update you in a few months to share how the oil performs over time. Worth the money to be honest, car engine feels more smooth. I will report the performance in due course. I hope it will keep functioning well and it keeps the engine cleaniness for the next year!

Excellent..!
Always undertake my own oil and filter changes on my vehicles, then at least I know what goes in and not fobbed off with some spurious stuff! I have used Castrol for years and will continue to do so. A tried and tested formula from a highly respected brand.

2002 Toyota Rav4 2.0 Petrol engine oil
Perfect oil for a 2002 Toyota Rav4. Used for a service. Doesn't have a pour nozzle.. had to use a cone to pour oil into engine but for the price not bad. great value for money. although 5 litre, not to bulky and can be easily carried and poured.
