Diesel Fuel Testing

Ensure your generator doesn’t let you down in an emergency situation.

One of the main causes of why generators fail to start or operate properly during a power outage is contaminated diesel fuel. Water, sand, rust and sludge clog fuel filters and ruin injectors causing engines to stall, smoke and not produce power. You can easily prevent this with diesel fuel maintenance. Our TSSA-certified technicians will test and, if required, clean your diesel fuel.

Does your fuel meet code compliance for Emergency Power Systems?

Fuel oil in any storage tank must pass an annual “Clear and Bright” Test required by CSA 282-09. Clear and Bright has no relation to the color of the fuel, it means no free water, no sediment and nothing clouding the fuel or floating in it. If the test fails, CSA 282 recommendations incorporated in the Canadian Electrical, Fire and Building Codes state that anyone storing diesel fuel for emergency or standby power generation must:

  1. Replace the fuel and clean the diesel fuel tank (not a cost-effective choice).
  2. Filter the fuel (polish) to remove any water, sludge and other contaminants.

We provide “Clear and Bright” testing to monitor the state of your diesel fuel. Upon completion of the sampling, we will
present you with a report outlining our findings and what, if anything, needs to be done to ensure your diesel fuel meets
CSA 282-09 standards.


If you want to be confident that your generator will run when you need it, invest in annual diesel fuel polishing. Fuel polishing (cleaning) is a process where diesel fuel is moved through a series of filters in order to remove contaminants such as water, bacterial and fungal microbes, dirt, sand, rust, metallic particles and sludge. By doing so, you can restore and revive the diesel fuel to a clear and bright state, your diesel-powered generator to perform at its optimum.


If you’re operating a facility that stores large quantities of diesel fuel an automated diesel fuel polishing system is the answer. As the description suggests, these systems will clean your diesel fuel automatically. The fuel filtration system will circulate the fuel from the bottom of the tank through filters, removing water and sediment and will then return the clean fuel back to the tank.
