Diesel testing is necessary for the detection and subsequent removal of contaminants such as water, fungus and microbes which can often develop into thick sludge, effecting the performance of your engine.
Stored diesel fuel will deteriorate over time and in several different ways. The most common is through water contamination (condensation). This is where water molecules can infiltrate the fuel molecules. Water then displaces the diesel fuel inside the diesel engine, increasing wear because of the absence of lubrication.
The infiltration of water encourages bacterial growth within the diesel fuel causing fine sediments and bacterial residues to form, these may eventually sink to the bottom of the tank resulting in filter blockage, fuel pump wear, diesel engine damage or engine shut down.
OCLS can assist you in determining whether or not the fuel you provide us is in need of some TLC; whether it be achieved through either filtration, polishing or in the worst case scenario – replacement.
Additionally, as a part of our standard suite of analysis for diesel, we test the fuel for Biodiesel content (FAME), Flash Point and Density; all of which are crucial in determining if there has been further contamination or potential misfuelling of an engine.
Additional tests such as Closed Filter Plugging Point, Sulphur Content, Cetane Index and more can be offered upon request.
We also test other fuel types including HVO, HFO, MGO etc.
For Petrol analysis, please contact the lab prior to sending in a sample for further information.
Water is the worst form of fuel contamination.
