## Description

This is the tool that every trucker, mechanic, or diesel-vehicle owner needs. 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 flowing down 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 8oz Long Neck bottle can treat up to 32 gallons of diesel fuel. For best results, always follow the directions listed on the bottle, as the suggested amount will depend on temperature, diesel type.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: Opti lube - Good product, these are nice size bottles, easier to carry in truck and long neck make it easier to use without dripping on paint.
Review: Removes junk from dirty diesel - The first filter/water separator on my Powerstroke gets dirty faster from OptiLube binding the junk in the fuel making the filter more effective. Significant MPG increase as well, at least 2-3 mpg. I run 8 ounces every fill. Even my active regens are improved by being more consistent & taking the DPF to 0% in less time it seems. The long neck bottles are awesome because the stuff stinks but the long neck bottles prevent it from getting on your hands. My son is getting some for Christmas bc I pay for the truck. I really believe OptiLube’s claims as I have witnessed them. I’ve been a Powerstroke driver since 2004. I put it in my diesel Kubota UTV and its top speed increased from 19 to 21 mph! It starts like the day I bought it with 6200 hours and consistent maintenance. Same with my John Deere 4066R
