Liqui Moly Molygen New Generation fully synthetic engine oil is carefully engineered, starting with a high quality synthetic base. What separates Molygen from other engine oils is the molecular friction modifier for reduced friction and wear. Because of this, Molygen glows fluorescent green under UV light, allowing you to easily find any leaks!

The fluorescent green chemical friction modifier smooths out hard metal surfaces, reducing overall engine wear and heat due to friction. Tests have shown to reduce the friction coefficient by 15%!� MolyGen oil is also a great choice for modern forced induction engines which produce much more heat. BMWs are notorious for leaking oil. Make chasing your leak easier with Liqui Moly Molygen New Generation engine oil. (Once you find it, give us a call - we can help you stop that leak, too!)
