We are an independent Amsoil dealer in Culleoka, TN. Amsoil is the worlds first synthetic motor oil. The introduction of the world's first synthetic motor oil to meet American Petroleum Institute service requirements in 1972 set all-new standards for motor oil quality. AMSOIL synthetic motor oil outperformed conventional petroleum motor oils on all counts. It was clear from the start that this innovative product would play a major role in engine performance and engine life. AMSOIL has remained steadfast in its commitment to quality and precision lubricant engineering, leading the charge over the past four decades with many industry firsts. This quality-first commitment has driven the introduction of numerous synthetic lubricants, premium filtration technologies and fuel additives.
