Review summary will appear here when enough rider feedback is available.
Initial prototypes for the first Scottoiler system appeared 40+ years ago, when Fraser Scott began to investigate and invest in the potential of his idea for a motorcycle chain oiler. As a life-long motorcyclist, the initial idea came to Fraser when he was commuting from Glasgow to Manchester on a regular basis. Due to the high mileage that Fraser was travelling, he found himself having to continually adjust or change his chain. Eventually, under the name of FM Scottoilers Limited, Fraser first made the Scottoiler available to the public in 1986, finally settling on trading as Scottoiler (Scotland) Limited in 1992. Since then, continual improvements and innovations have culminated in today's range of products. The popularity of Scottoiler products globally has created an ever expanding workforce with its HQ based in Milngavie just outside Glasgow. With a strong R&D function continually developing future Scottoiler products, the company plans to bring the benefits of their product range to a much wider global community in the future.
