Bought for BMW GSA 1250 as an emergency top up. Always good quality oil and easy to use.

### ⭐⭐⭐⭐⭐ Brilliant 👌🏻
*by D***Y on 9 May 2025*

I’ve been using Castrol POWER1 4T 10W-40 in my bike and it’s been brilliant. The engine feels smoother, starts quicker, and runs noticeably quieter. Gear changes are slicker too, especially when the engine’s warm. It gives me confidence on longer rides, knowing the engine’s well protected. The 4-litre bottle is handy—plenty for a change with some left over for top-ups. Definitely good value for money and a brand I trust. Great quality and price highly recommended 👌🏻
