- Reduce the cost of the fuel. Adulterants can be cheaper than the actual fuel, so adding them to the fuel can increase the profit margin for the seller.
- Increase the fuel's performance. Some adulterants can improve the performance of the fuel, such as by increasing the octane rating or the lubricity.
- Change the fuel's color or odor. Adulterants can be used to change the appearance or smell of the fuel, which can be useful for disguising the fact that it has been adulterated.
Some common adulterants include:
- Water. Water is the most common adulterant used in fuels. It can be added to fuel to increase the volume of the fuel and thus reduce the cost. However, water can also damage the engine if it is not removed before use.
- Alcohol. Alcohol can be added to fuel to improve its performance. However, alcohol can also lead to corrosion and engine damage if it is not properly blended.
- Gasoline. Gasoline can be added to diesel fuel to increase the octane rating. However, gasoline can also damage the engine if it is not properly mixed with diesel fuel.
It is important to be aware of the potential for fuel adulteration and to take steps to protect yourself from it. This includes:
- Buying fuel from a reputable source. It is less likely that fuel purchased from a reputable source will be adulterated.
- Inspecting the fuel before use. Look for signs of water contamination, such as a milky appearance or the presence of sediment.
- Using a fuel stabilizer. A fuel stabilizer can help to prevent the formation of gum and varnish, which can be caused by adulterants.
If you suspect that your fuel has been adulterated, you should stop using it immediately and have it tested by a qualified mechanic.
