Quality oil from Castrol
4l was needed for my Ninja 9, so no waste and having to pay for unwanted literage for next time. Castrol is a recognised quality brand which I have used many times in the past without any issues. Delivery was next day. No problems.

Smooth oil
One of the cheaper oils on the market but by no means seems it! I have a Very smooth engine now however! Very good value imo. Although won’t improve performance, should improve engine life!!

Brilliant 👌🏻
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 👌🏻

Trusted Oil That Keeps My Bike Running Smoothly
I’ve used Castrol POWER1 for years and it’s always been reliable. The bike runs smoother, gear changes feel cleaner, and it gives good protection even on longer rides. Easy to pour with the smart bottle design. A brand I trust and definitely worth sticking with.
