Diesel Fuel Test Kit
The diesel fuel testing kit includes UPS shipping both ways to the lab (continental US only). The lab will run the following tests on the sample to determine the fuel’s condition.
- Spectral exam
- Flashpoint
- Specific gravity
- Insolubles
- Moisture testing
Note: Fuel kits are only available within the continental US and cannot be shipped to Hawaii, Alaska, or internationally.
Description
Determine your fuel’s condition with our diesel fuel kit!
Our diesel testing kit includes UPS shipping to and from Blackstone Laboratories in Hazmat-certified containers (continental US only). It also includes the following tests, with commentary on whether the fuel meets specifications in the following areas:
- Spectral exam – ideally the spectral exam will be all zeros, or close to it
- Flashpoint – should be 160F or above
- Specific gravity – we’ll tell you if the SG is in the correct range or not
- Insolubles – no solids should be present
- Moisture testing – no significant moisture should be present
Those tests will tell you whether the fuel meets specs for diesel fuel.
One of the main questions we get about diesel fuel is whether it’s been contaminated with gasoline. The flash point test addresses this; when gas is added to diesel, it lowers the flashpoint. The extent of the contamination depends on how much gas was added. If a teaspoon was added, it might not make much difference. If an entire tank was filled with the wrong fuel, we’ll be able to tell.
We do not test cetane ratings on diesel fuel. And we cannot tell you if it’s biodiesel.
Checking for DEF is not part of the standard test, but we can look for physical indicators of DEF contamination: an ammonia smell, and crystalline solids in the fuel.
The insolubles test looks for debris, but if debris doesn’t make it into the sample bottle, we might not see it in testing. If we do find debris, we’ll quantify it if possible, though we can’t necessarily tell you what it is and how it got there.
This test does not determine a fuel’s cetane rating.
