This is a two part process.

We send you two field tests, one to detect DEF in fuel and one to detect bacteria/algae in fuel.

These tests are done by you in your facility.

We also will send you the container and a postage paid package to return the sample to the lab by Priority Mail. Once the lab gets the sample the test is completed and results are emailed to you within 72 hours.

This laboratory portion will give you a pass or fail report as to the fuel quality based on these characteristics:

API Gravity
Cetane Index
Water by Karl Fishcher
Distillation
Flash Point
Water & Sediment
Particle Count

The price is $249.
We will send you the sample container and a postage paid package to return the sample to the lab by Priority Mail same day it is ordered.
Once the lab gets the sample from you, you will be emailed test results within 72 hours.
