The Scottoiler Top Up Oil is a high-quality lubricant specifically designed for use with Scottoiler systems. Two oils are available: 'Traditional' (Standard) and 'High Temperature', in various sizes. The 'Traditional' oil is suitable for normal temperatures, while the 'High Temperature' oil is designed for hotter climates. A 500ml bottle provides approximately 10,000 miles of riding. Both oils share the same chemical makeup, but the 'High-Temperature' (Red) version is more viscous and thicker, causing it to flow more slowly at higher temperatures than the traditional blue Scottoil. All other features and characteristics are the same, and the oils can even be mixed.
