Good Price, Free Shipping from Amazon Prime, and Great Product
After much research I ordered this product and was not disappointed. In a world where everyone is an expert, due to the internet, I will not pretend to know the chemistry behind this oil. If the oil is synthetic, which the label says it is, and the oil is the viscosity is made for lower units, which the label says it is, then it should be good. Star Brite has been a good product line for me. I have purchased cleaners, polishes, and other types of their products and never been disappointed.
