- MADE FOR OPTIMAL LUBRICATION: Your truck has been there for you every minute and every mile, which is why it’s important to keep it in pristine condition and the tools in the toolbox. At Opti-Lube, our goal is to keep your engine operating at its best. Our fuel additive helps to increase the lubricity properties of ultra-low-sulfur diesel (ULSD) so that you can play more and worry less.
- IMPROVES FUEL ECONOMY: Trucks are known for eating up fuel. Fortunately, there’s a way to fix that with Opti-Lube XPD formula. This diesel fuel additive has been shown to enhance fuel mileage year round, giving you more bang for your buck. With greater fuel economy, you’ll find increased power for both summer and winter driving.
- ENHANCES PERFORMANCE: Whether during rain, snow, or shine, Opti-Lube XPD formula delivers. It works to improve the performance of your truck all year round. This fuel additive also helps separate water from Diesel fuel as a demulsifier and more than doubles the storage life of standard diesel fuel. Contains enough Anti-Gel to keep fuel flowing down to -10F*.
- ECONOMY: With a treatment rate up to 512 gallons it will cost you just pennies per treated gallon. This diesel fuel treatment isn’t just limited to trucks; use it for your farm and construction equipment too!
- CLEANS INJECTORS: When your fuel injectors build up with residue, your engine usually doesn’t run as efficiently. Opti-Lube XPD formula cleans injectors while helping prevent future build-up. This helps to reduce deposits and emissions, making this lube compatible with all vehicle emissions systems. Additionally, it acts as rust and corrosion prevention to keep your vehicle in tip-top shape.
