What is our most asked question? It's "What's the Difference?"
XPD is by far our most popular product as it is an All-In-One solution that covers all bases when it comes to a Diesel Fuel Additive. You can run it year round in all Climates. High Lubricity, Cleaners, Cetane, Water Control, and Anti-Gel.
If you only concern is Lubricity, XL is a great option.
If you want to have a high quality Lube and Cetane Booster at a lower cost, Summer Lube+ Cetane might be your go to.
If you want the most Cetane you can get, BOOST! Maximum Cetane is your best bet.
And if your main concern is keeping your stuff running in the coldest months, Opti-Lube Winter will be what you reach for.
