Review: Good brand for cetane - I'm giving this 5 Stars even though one of my bottles was leaking and got all over everything but it wasn't an extreme amount but enough to get over everything and make a mess but anyway besides that this is good cetane and can easily be gotten from desertcart and I will buy again when this runs Out Review: it works - I notice a change in the combustion sound of the engine. The car runs a lot better but didn't notice any mpg gains. ## Features - BOOSTS CETANE LEVELS. Increases diesel fuel cetane rating by up to 7 points, improving ignition speed and combustion quality.
