Quick delivery as always

Haven't used it yet but delivery was quick as usual from Sportsbikeshop. Can't comment on the performance of the product, but not expecting any issues from such a well known brand as it exceeds the requirement of my bike spec.

Liquid perfection

Have been using Castrol oil for many years trouble free. Excellent performance even if engine oil is pushed over recommended time limit. As to the shop, well it's SBS, not only the best price but top costumer service.

It's good oil

It's a well known brand with a good reputation. I've used it in all my MCs without any issues - z650, Z1000SX x2 and a Ninja 1000SX.

Liquid Gold

Will let you know how good it is when I do an oil change, but I chose Castrol Power because of the standing it has in the lubrication marketplace.

Happy Customer

Really happy with the whole shopping experience buying from Sportsbikeshop. Castrol Power is a quality product matched well with my machine and will help to protect and cool it for many many miles. It maynot be the cheapest but it will pay dividends using it over time.
