I have been useing some stuff called Extralube ZX1 and have had great results with it, bought the first bottle from QVC so if it didnt work i could get me money back, i use it in my car, my boat and customers boats and been using it for years now, great product.
 
I thought it was good stuff, put it in their engine, ran it, emptied the oil out and it ran for 50 miles or summat? Taxi for me...
 
IF YOU GUYS want an interesting product-one that disappeared
