Customer Testimonial:
"I have never written, or been motivated to write, a testimonial for a product before. This time however, in light of the energy and economic crises, I feel I may actually be able to do those that read this a great favor.  I have been using MotorSilk engine oil treatment for at least 5 years now, in five (5) vehicles, and have been flabbergasted with how effective it has been in all my vehicles with regards to improved engine performance and greatly improved fuel economy. I have used it in my 2002 Nissan Pathfinder (15% increase in mileage), 1942 Willy's U.S. Army WWII jeep (10% improvement), 2004 BMW Z4 (This vehicle uses synthetic motor oil and my fuel economy actually increased from 29 to 35 mpg, a 20% improvement), 2008 Toyota 4-Runner, V8 (20% improvement), 2008 Lexus sedan (17% improvement), and a 2007 Subaru Outback (12% improvement)."
