Your cart is empty. Diesel Fuel Supplement +Cetane Boost is a winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop, paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine, and water in the fuel can freeze on the facings of fuel-filters, blocking fuel flow. It provides trouble-free winter operation for diesel fuel.
Diesel Fuel Supplement +Cetane Boost is intended for use only during cold winter months when temperatures drop below +30F. Use Diesel Kleen +Cetane Boost (in the silver bottle) for peak performance in non-winter months. If your vehicle will not start or gain power in cold temperatures, use Diesel 911 (in the red bottle).

$40 dollars for one bottle, very complicated picture of product shown on picture with 6 pack box. Seller should show single bottle, and tipped one bottle for sale.

Love this product and it was a better value this way. Unfortunately I actually never received it as it got lost somewhere in transit so I had to go and buy it from the store because I needed it. It’s sad that sometimes things being shipped either don’t come or they get lost somewhere. Thank you for the refund.

I use it to keep the algae from getting bad enough to require replacing the fuel filter more often.

This product will take care of diesel fuel as far as gelling and also lubricates the injectors... been using it for 15 years..

I use it for my outside home heating oil tank. By adding this before the delivery I am confident that the oil won't gel and my system won't stop working. New England winters can be cold! Have been using it for years and have never had an issue ( knock on wood) since! I like that I can order it here and two days later it's at my door, instead of having to go to the store to pick up. I ordered oil for delivery, hung up and ordered this from my phone and didn't even have to leave my house! Love that I stayed warm in the process! Great product.

I've used Power Service for a long time on various Diesels. I certainly notice a difference in power and fuel economy during the winter months, when Diesel suppliers lower the Cetane in their fuel.Me including many others, highly recommend this product if you own a newer Common Rail style diesel. These newer style injection systems pump fuel at a very high rate and added with the lower lubricity of Ultra Low Sulfur diesel, this is a must! VW's especially are known for their HPFP (high pressure fuel pump) failing and causing thousands of dollars due to a poor pump design and lack of proper lubrication.I always make sure to add in some at every fuel up. White bottle in the Winter, Grey bottle in the Summer.The only drawback to this large bottle, is that it makes pouring into the tank a messy task sometimes. Especially during windy day's. I'd like to see them include a built in spout into the bottle, similar to the design some gas injection bottles have. Where you can calculate the exact amount you want to add with a no frills and spills clean design. For the time being I just use a funnel and try to be careful.

A popular winter treatment for ULSD to prevent gelling and lubricate your fuel system. I use Power Service products year round to prevent fuel problems from water, clogged injectors and worn out injectors or fuel pumps.. Some people think this diesel additive does not work because its hard to treat the fuel after the cloud point occurs (below 40 degrees). For best results, use in every tank to prevent the wax crystals from forming and plugging your fuel filters. This diesel conditioner treatment helps to separate water from the diesel fuel and prevent cloudy or frozen fuel lines. This diesel fuel conditioner will only cost you a few cents per gallon and save you hundreds of dollars in repair costs. SlickDiesel also passed the HFRR test for lubrication.
