Power 1 Castrol 4T 10W-40 Motorcycle Oil 4L

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.

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

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 👌🏻

Quality best, bit expensive can get 5 litter in same price. Suitable for my car. Increase performance, fit, all good

I've only used this oil on my bike. Never had any issues with it. Good stuff

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!!

Good value, best oil to use in my Thruxton. Easy to select the correct amount with the measure on the bottle. Won’t use any other oil.

Always just good stuff this
