I went to my local motorcycle shop and asked them for engine oil for my bike and was given a can of an unknown brand to me that I wasn't going to be happy with and which cost me £48, I returned it when I saw the offer on Sportsbikeshop.co.uk and purchased this top quality Castrol Power1 oil for just under £32 delivered, it was like liquid gold pouring out of the can and into the funnel and into my engine, knowing I'd bought the correct oil at a brilliant price has given me total piece of mind when starting my bike up, and knowing that the Castrol Power1 wil do exactly what I expect it to do and make my engine sound and feel like the rolls royce of engines for motorcycles.
