Excellent item and great price, just what I needed

### ⭐⭐⭐⭐ Oily oil
*by L***Y on 16 June 2024*

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!
