There are several benefits to using Opti-Lube XPD Formula Diesel Fuel Additive. This handy additive increases lubricity, improves fuel mileage, keeps your tank clean, and enhances your truck’s performance.Over time, build-up and residue occur within your fuel injectors, which decreases your truck’s efficiency. As this additive lubricates your fuel injectors, it helps reduce fuel system wear. This, in turn, creates a cleaner tank so that you can enjoy improved fuel mileage and a better running engine. Additionally, this additive prevents future build-up.It also fights against rust and corrosion, keeping your vehicle in pristine condition. This additive boosts cetane by up to 3 points and contains an anti-gel that keeps your fuel from flowing to -10 F°*.Upon adding Opti-Lube XPD Formula, you’ll notice a significant difference in the way your engine runs. It will run more smoothly, giving you optimal performance. As a note, diesel fuel cannot be at or below the cloud point when preventative anti-gel is added. If the fuel is cold and wax has already begun to crystallize, the cold flow additive will not be able to modify the crystals. This is because cold fuel has poor solubility, so it will not mix with the additive. One of the easiest ways to ensure this additive is properly mixed is to add it at the pump while fueling.Each 4oz bottle will treat up to 16 gallons of diesel fuel.This fuel additive is made specifically for ultra-low-sulfur diesel (ULSD). It’s time to upgrade your truck’s fuel capabilities by adding this fuel additive to your car care supplies. Order today! Review: Must have additive for diesel engine owners - All diesel powered vehicle owners need to know about this additive. Refiners stopped adding lubricant to diesel fuel that preserves and extends the life of the engine. Add one bottle for every 16 gals when filling up and take care of your diesel engine.
