Refiners manufacture ultra-low sulphur diesel fuel using a process called hydro-treating. While this process is very good at removing sulphur, some beneficial properties of the diesel are also removed. When you purchase ULSD, most likely the distributor has used additives to to improve the lubricity. Unfortunately, you don't know what you are buying. To protect your engine and for piece of mind, use Stanadyne diesel fuel additives. Our best seller is Performance Formula, as it provides increased lubricity, increased cetane (energy), cold weather protection, and gains of up to 9.6% MPG.
