Prevent Car Engine Contamination

If you regularly maintain the diesel engine of your vehicle, you can ensure smooth, efficient, and reliable performance for several years. Common regular maintenance includes changing the engine oil and oil filter, fan belt check and replacement, timing chain replacement, and engine recalibration at prescribed time periods and mileage, whichever comes first. Companies such as provide these filters for your 4WDs and light commercial vehicles.

Check Your Diesel Fuel Filter Too!

Often, however, forgetting one maintenance check up is one that could compromise engine performance or, worse, damage the engine to the extent that could create a larger expense. The effects of this failure are not as immediately apparent, but when you notice it, the damage is extensive.

This maintenance activity is simple: Check the diesel fuel filter of your vehicle’s engine for excessive contamination. The fuel powering a diesel engine often has contaminants like dirt, scale, rust, and even water. When these enter the engine, they could clog up its fuel injector and carburetor.

The main source of these impurities is the fuel tank which corrodes over time. Another source is bio-diesel, which is gaining popularity because of its fuel system cleaning properties. While it is beneficial to the fuel system, it introduces more contaminants that tend to clog up your engine’s fuel filter faster.

A clogged up fuel filter allows less fuel into the engine than needed, resulting in decreased engine performance. When the contaminants themselves enter the engine, however, one result would be an inefficient burning of the fuel which leads to higher-than-allowed smoke emission and increased fuel consumption.

Checking for excessive contamination of the fuel filter should be done as often as your oil change schedule, and replacement using a diesel filter kit should be done once it is determined that the filter is already clogged up. To be on the safe side, change your filter once every one or two years.


An ounce of prevention is better than a pound of cure. You need to maintain your vehicle regularly. Whenever you have your maintenance check ups, make sure to check your fuel filter. It could spell the difference in your engine’s performance.
