Hey diesel owners, this Power Service Diesel Kleen is seriously good stuff for keeping your engine running smooth! The 2.5 gallon size is perfect if you go through a lot of fuel or want to stock up. It boosts cetane up to 6 numbers, which means faster cold starts, smoother running, and less of that annoying power lag when you need to accelerate. It cleans out dirty injectors and prevents them from sticking - super important for modern High Pressure Common Rail systems. The Slick Diesel Lubricator protects your pumps and injectors from wear and tear, plus it prevents sludge buildup that can clog up your filters. You can actually see improved fuel economy up to 8% - the savings on fuel pretty much pay for the additive itself! It works with all diesel fuels including Ultra Low Sulfur Diesel, biodiesel, and blends. Just remember - this is your year-round performance formula, but when temperatures drop below 30°F, you'll want to switch to their Diesel Fuel Supplement (the white bottle) for winter protection. If you want to restore lost power, smooth out a rough-running engine, and protect your fuel system, this Diesel Kleen is definitely worth adding to your maintenance routine. Your truck will thank you!
