What’s the Difference Between Opti-Lube Diesel Fuel Additives?

One of the most common questions we get is: what is the difference between your diesel fuel additives? The short answer is that each product is designed for a different need.

Quick Product Guide

XPD All-Season

XPD All-Season is our most popular diesel fuel additive because it covers the widest range of needs in one product, including lubricity, cleaning, water separation, corrosion protection, stability, cetane improvement, and cold-weather support.

XL Extreme Lubricant

XL Extreme Lubricant is the best choice when maximum lubricity is the main goal and anti-gel protection is not needed.

Summer+ and Boost!

Summer+ is a warm-weather formula with lubricity, cetane, detergency, and performance benefits. Boost! is the best choice when the main goal is maximum cetane improvement.

Winter, Single Clean, and Gel Melt

Winter is for stronger preventative cold-weather anti-gel protection. Single Clean is for stronger one-tank cleaning. Gel Melt is for emergency use when diesel fuel is already gelled.
