Spotgun Jr.™ cartridges are easy-to-use without mess or spills. A/C ExtenDye™ is enhanced with an additive package that extends the life and improves the efficiency of the A/C system. A/C ExtenDye is a super-concentrated UV dye that includes a friction modifier to increase the lubricity of the compressor oil, improving efficiency (friction coefficient) by over 50%, improving fuel economy. It also includes an anti-wear additive which creates a film that prevents contact between metal parts; reducing friction and heat, thereby extending component life; plus it includes an antioxidant to stop the oxidation process, reducing acidity and prolonging oil life.
