This new generation oil is made with a quality synthetic base and includes a molecular friction modifier for reduced friction and wear. It also glows under UV light so leaks can be easily traced! This unique oil contains a fluorescent green chemical friction modifier to smooth out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown a reduction in friction coefficient of as much as 15%! MolyGen oil is also a great choice for modern turbocharged engines which produce much more heat.
