Tired of Measuring Diesel Additive for Every Tank?

Measuring diesel additive every time you fill up does not have to be complicated. The key is to know your tank size, understand the treatment rate, and use a container or dosing method that makes the amount easy to repeat.

Use the Right Treatment Rate

Treatment rates vary by product, so follow the directions on the bottle or product page. For example, XPD All-Season is commonly used at 1/4 oz per gallon of diesel fuel.

Make Dosing Easier

• Keep a dedicated measuring bottle in the vehicle.
• Pre-measure common amounts for your usual fill-up size.
• Add the product before or during fueling when possible.
• Use the same routine each time to avoid underdosing or overdosing.

What If You Add a Little Too Much?

A small amount over the recommended dose is usually not a concern. However, significantly overdosing generally does not provide extra benefit and is usually not cost-effective.
