We have realized an overall increase in fuel economy in the range of 8-10%!

We learned about the Lucas Oil Marine Fuel additive about 5 years ago and have been using it with great results ever since. We run two heavy duty work boats on a daily basis in harsh marine conditions. Since we stated using this product, we have realized an overall increase in fuel economy in the range of 8-10%! In addition to the fuel additive, we also use the Lucas CK4 oil to which we add the Lucas Oil stabilizer, which allows us to extend our oil change intervals, resulting in substantial annual cost savings. Our boats are critical to our operation and we trust the Lucas Oil products to keep our boats going strong!
