I just got done reading a fairly interesting report on ZMax title Zmax The Facts. The test results seemed to be extensive and credible. Being pessimistic about pour in the fuel tank and crankcase performance products I was impressed with the reading. Any personal experiences with this stuff. One of the tests in the artical included a 1200cc yamaha engine. The yamaha engine saw a 6% or 7% increase in performance. Still seems hard for me to believe. Other positive results were better fuel economy,engine friction reduction "valve quides mentioned" ect. Feedback a waiting!!!
