SCOTTOIL REFILL BOTTLE 500ml Blue Standard: Bottle.

Because of its increased viscosity, this oil is also better suited for use with older Scottoiler kits or with faster flowing oilers. This makes it ideal for touring abroad or, long hot UK summers. 

Scottoiler's Red Oil is designed for warmer climates and should be used in ambient temperatures of 20-40?C. 

Scottoil - Ambient Temp. (500ml bottle) Unfortunately Scottoiler no longer include these spouts with the bottles. Obviously this is something to do with them trying to reduce their "plastic footprint" etc etc. They are trying to encourage people to re-use the original one that came with the kit.
