## Overview

Opti-Lube XPD All-Season Diesel Fuel Additive is a premium 4oz formula designed to boost diesel engine performance by increasing cetane levels, improving fuel economy by up to 15%, and cleaning fuel injectors to prevent buildup. It also protects against rust, corrosion, and fuel gelling down to -10°F, making it an essential year-round additive for trucks, farm, and construction equipment running on ultra-low-sulfur diesel.

## 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 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: Fast shipping and quality product. - Works as stated and will purchase again
Review: Works like magic - This thing is like magic, I use it in my Hilux 2.8 Turbodiesel, I had this vehicle for 5 years and always filled my tank locally (Mexican Diesel), after a few minutes of using this additive for the first time. It was like a new car, les noise, much smoother throttle. I am getting around 10-15% better milage. I can honestly say that at least with mexican diesel, this does wonders.
