Review: The price and quality of product made me try it. It's been a good change. However, the large jug was shipped in just a plastic bag. The nosel was bent and the cap broken so could never seal it back up without it leaking. Recommend shopping in a box.
Review: Great products, love taking care of our diesel adding protection, performance. Competitive price.
