Modern fuels introduce contaminants that affect performance
Modern fuels, while meeting the required specifications, may introduce contaminants that can affect the performance of your vehicle. Fuel contamination can occur due to various factors, including storage issues, delivery mechanisms, temperature changes, and humidity. These contaminants can lead to vehicle downtime and costly repairs, especially for complex and expensive systems.
The most common contaminants found in modern fuels include particulate matter, debris, water, microbial growth, and incompatible fuels. Particulate matter and debris can enter the fuel during transfer between storage tanks and when exposed to the atmosphere. Water can enter the fuel from storage tanks and condensation due to cooling temperatures. Modern engines require improved fuel filtration technology to ensure that the fuel delivered to the vehicle's fuel system is clean.
Fuel contamination can directly impact vehicle performance. Signs of contaminated fuel include poor acceleration, excessive smoke, decreased fuel efficiency, and engine misfires. In addition, visual indicators inside the fuel tank, such as corrosion, rust, sludge, or mold growth, can signal contaminated fuel.
To address fuel contamination, it is crucial to completely drain the fuel tank, removing all contaminated fuel, water, and debris. Afterward, thoroughly clean the inside of the tank to eliminate any remaining contaminants. In severe cases, replacing the fuel tank may be necessary. Regularly inspecting your fuel tank and maintaining proper fuel storage and handling practices can help prevent fuel contamination and ensure the optimal performance of your vehicle.

Ethanol and carbon are common contaminants in older vehicles
Ethanol, also known as ethyl alcohol, is an additive derived from corn that boosts octane. It was initially introduced to reduce emissions and improve air quality, but modern engines no longer require this aspect of ethanol, and it is now primarily used as a cost-saving measure. While ethanol has environmental benefits and can lead to lower evaporative emissions, it can also produce by-products that build up and clog fuel injectors. This buildup can negatively impact the fuel economy and performance of a vehicle.
Carbon, in the form of carbon dioxide (CO2), is another contaminant that can affect older vehicles. The combustion of ethanol in engines releases CO2, but this is offset by the amount of CO2 captured when the corn plants used to make ethanol are grown. However, the use of ethanol can still result in emissions of regulated pollutants, toxic chemicals, and greenhouse gases (GHGs).
To prevent issues caused by ethanol and carbon buildup, it is important to regularly clean your fuel injectors and fuel system. This can be done by using a fuel injector cleaner, which breaks down deposit buildup and helps prevent new deposits from forming. The frequency of cleaning depends on the vehicle and its usage, but it is typically recommended to use a fuel injector cleaner every 5,000 miles or every other oil change.
By maintaining your fuel injection system and keeping it free from contaminants, you can ensure optimal vehicle performance, fuel efficiency, and reduced emissions.
