The POWER SERVICE diesel kleen & cetane boost fuel additive in a 64 oz. container enhances diesel performance by promoting smoother engine operation and minimizing engine hiccups. It reliably prevents fuel gelling in cold weather, facilitating consistent engine starts even in frigid conditions. By improving lubricity, this additive reduces wear and tear on critical engine components, potentially prolonging engine life. Additionally, it restores lost power and acceleration by optimizing fuel flow dynamics within the engine system. It also contributes to a cleaner engine environment by reducing exhaust smoke and particulate emissions.
