At Harold's Used Auto Parts Inc in Philadelphia, PA, we know that fuel contamination is one of the priciest and most problematic issues that may plague a diesel engine. There are a variety of issues that cause contamination in fuel. Knowing these issues will help drivers become aware of fuel contamination and hopefully prevent these issues. 

Particulate Contamination - From rust to microscopic debris, anything in diesel fuel besides diesel fuel is generally a bad thing. Even the tiniest debris can destroy an engine - the enormous pressures flowing through injector pumps and fuel injectors make for a dangerous equation when the debris is added to the mix.

Water Contamination - Water in your fuel system is bad news. It prevents lubrication, which is destructive to moving parts with very specific tolerances. It also causes poor running conditions and has even been known to cause injector tips to explode if the conditions are right. Another issue is that water can freeze inside of lines and components during winter conditions.

Old Fuel - Diesel fuel goes bad over time. More specifically, it begins to degrade, and that will contaminate the fuel system. From lubrication issues to sludging effects and more, bad diesel fuel is an issue that must be dealt with effectively.

Microbes - That’s right, living organisms in the fuel tank can cause contamination. If water is allowed to settle in the tank, microbes will flourish in the layer where diesel fuel and water meet, feeding off of elements in the fuel as it mixes with the water. These microbes also generate sludge, which will clog lines and filters and damage fuel components. Symptoms of fuel contamination There are some symptoms of fuel contamination to watch out for. Engines that run poorly or erratically, when mechanically everything is fine, are possibly subject to fuel contamination. Clogged filters and sludge in the lines is a sure sign of contamination. Injectors, pumps, and other components wearing or failing prematurely is also likely the fault of something that has contaminated the fuel.

What To Do About Contamination - Most importantly, don’t ignore it. It takes very little contamination to destroy an engine, and the chances of just running it until the contamination is gone are slim. Even if you manage to burn through the contaminants, there’s a good chance irreversible damage will be done in the process.

It’s a good idea to consult our professional technicians on the matter - sometimes the system can be flushed, or a fuel contamination kit may be needed to correct the issue. No matter your repair or maintenance needs, our technicians have you covered. For the best diesel and fleet service shop in Philadelphia, PA call or stop by Harold's Used Auto Parts Inc today.
