This handy additive increases lubricity, improves fuel mileage, keeps your tank clean, and enhances your truckâ s performance.Over time, build-up and residue occur within your fuel injectors, which decreases your truckâ 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, youâ 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.This fuel additive is made specifically for ultra-low-sulfur diesel (ULSD). Itâ s time to upgrade your truckâ s fuel capabilities by adding this fuel additive to your car care supplies. Order today!

Standard treat rate is 1/4 oz per gallon of diesel fuel, or 1/2 oz per gallon if temperatures are consistently below 32F. For a 32 gallon tank you will use 8 oz, or 16 oz if it is consistently below freezing (32F). **Q: I saw a study showing the usage rate to be 13 ozs per 26 gallons of fuel, has this changed? I see now the concentration calls for 8 ozs.** A: The most recent lubrication tests have been done at the 1/2 once per gallon so 13 oz per 26 gallons. That is the premium ratio listed on our website. You may just want to experiment with your truck to see where it runs the best. start with the 13oz and lower each tank going forward and see if you get better fuel mileage. If your in colder weather, you may want to stick with the higher ratio till it warms up. **Q: Why is this priced 50% higher than msrp? msrp is $53.65 a gallon** A: Check the vendor. Or order directly from Optilube. Amazon vendors are free to charge whatever they want, **Q: Can you run this in summer as well. I ask because it performes better than the summer Opti - lube formula when it comes to lubricity** A: Many customers run the XPD year round. Some for different reasons but the HFRR tests is one reason. Others so they only have to handle 1 formula and can buy in bulk. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Génial *by G***N on 27 December 2025* Wow, vraiment surpris, résultat instantané moins de bruit moteur meilleur réponse du moteur merci beaucoup très satisfait ### ⭐⭐⭐⭐⭐ Opti - Lube XPD for Diesels *by P***N on 26 February 2026* I am on my 3rd gallon of this Product Opti - Lube XPD Diesel fuel treatment.
