Several people have commented about using the correct oil based on temperature. The way oil viscosity changes (oil thickness) based on temperatures is measured with a chart called a viscosity index. This is basically a line that shows the viscosity of an given oil across a range of temperatures. The more curved the line, the more the oil is being affected by temperature change. The perfect oil would be a totally flat horizontal line maintaining the exact same viscosity at all temperatures. So far, no chemist has been able to achieve this; however, in our labs we have been able to get closer to this "Holy Grail" of perfection with our 100% Fully Synthetic motorcycle oils than any other company.
AMSOIL was the 1st company to make a synthetic oil for motorcycles and has been the world leader in Synthetics for 40 years - it's all we do. Your Super Tenere can use our 10w-40 Motorcycle Oil in all seasons with excellent performance and protection regardless of temperature!
