Fuel analysis at diesel testing lab examines the state of the product in terms of certain problems which may have occurred since the fuel left the refinery gate. A proportion of diesel engine failures can be directly traced back to the quality of the fuel which was in use. Fuel contamination, degradation or adulteration can have serious consequences in terms of blocked filters, stuck or worn injectors, poor spray patterns and atomization.
Fuel can change between the refinery and the engine. It may pick up water during storage, collect dirt and rust from tanks and pipes, or degrade over time. It may also be mixed with other products. Testing shows which of these problems is present.
Middle East Testing Services and Research Centre, provides diesel testing services to determine the product’s remaining life along with its cleanliness and also ensures compliance with industry standards and norms. We offer a comprehensive range of services for petro chemical products and its contamination testing.
The table below shows common diesel tests and what each one tells you.
| Test | Why It Matters |
| Appearance | Cloudiness, colour changes or visible particles can point to water, dirt or degradation. |
| Water content | Water causes corrosion, supports microbial growth and damages injector pumps. |
| Sediment and total contamination | Solid particles block filters and wear injectors. |
| Sulphur content | Shows whether the fuel meets the sulphur limit, and it helps reveal tampering. |
| Marker dye | Shows whether dye has been removed from fuel that should carry it. |
| Density and distillation | Check that the fuel has the expected make-up and has not been mixed with other products. |
| Flash point | Shows whether lighter, more flammable products have been mixed in, and it is a key safety value. |
| Cetane number or index | Measures how easily the fuel ignites, which affects starting and smooth running. |
| Viscosity and lubricity | Affect how well the fuel flows and how well it protects the injection system from wear. |
| Cold flow properties | Show how the fuel behaves in cold weather, when wax can block filters. |
Diesel washing has been found commonly now, water acts as a by- product in washing process which can cause damage to injector pumps. Chemicals are used to remove dye as it can cause serious harm to engines.
Diesel washing is a highly illegal practice and hence it is essential to go for testing services to check the quality in order to determine the presence of marker dye and sulphur content levels. The sulphur content level cannot be reduced during the washing process and can be a clear indication of whether the fuel has been tampered with as well as residual dye left behind.
Marker dye is added to certain fuels so that they can be identified. When someone strips the dye out, the chemicals and water used in the process can stay in the fuel. A result that shows missing dye together with a high sulphur level is therefore a strong warning sign.
Bad fuel often shows up in the vehicle or equipment before it shows up in the lab. Common signs include:
If you see these signs, a diesel test can confirm whether the fuel is the cause.
