“The castrol 10w40 4t power 1 engine oil is fantastic for my suzuki gsxr600 k7 race engine.
Its very good quality and doesn't need changing too often,the only thing that lets it down is the price especially from opie oils who dropped the price by £22 after id bought it very annoying as id bought 20 litres.”
Thanks for the review.
