Problems You Might Encounter Running Biodiesel

Jul 13, 2018


Welcome to Grafco Electric, your trusted partner in the biodiesel industry. In this article, we will discuss some common problems that individuals and businesses often encounter when running biodiesel. We understand the technical complexities and challenges associated with biodiesel operations. Our expert team is here to offer you comprehensive solutions to ensure smooth and efficient operations.

1. Fuel Quality

Biodiesel fuel quality is a critical factor that can greatly impact the performance of your engines. Problems can arise when the fuel contains impurities, such as water, sediment, or contaminants. These impurities can clog fuel filters, fuel lines, and injectors, leading to decreased engine efficiency and potential engine damage. Grafco Electric provides high-quality biodiesel fuel solutions, ensuring that your engines receive clean and pure fuel, minimizing the risk of experiencing fuel-related issues.

2. Cold Weather Performance

One significant challenge when using biodiesel is its lower cold weather performance compared to traditional diesel fuel. Biodiesel can solidify or gel at low temperatures, affecting its flowability and causing starting problems or reduced engine power. Grafco Electric offers innovative cold flow improver additives specifically designed to enhance the cold weather performance of biodiesel, preventing gelling and ensuring optimal engine functionality even in extreme weather conditions.

3. Oxidation and Stability

Over time, biodiesel can undergo oxidation, leading to the formation of harmful compounds and degradation in fuel quality. This oxidation process can be accelerated by exposure to heat, oxygen, and light. The result is increased acidity, gum formation, and sediment build-up, which can adversely affect your engine's performance and longevity. Grafco Electric provides advanced fuel stabilizers and antioxidants that help prolong the shelf life of biodiesel, preventing oxidation and ensuring fuel stability.

4. Fuel Contaminants

Contaminants in biodiesel fuel can lead to various engine problems. Water, for example, can cause microbial growth, corrosion, and fuel system damage. Additionally, contaminants like dirt, rust, or particles can clog fuel filters and injectors, obstructing fuel flow and causing engine performance issues. Grafco Electric offers comprehensive fuel filtration systems and solutions that effectively remove contaminants, ensuring clean and pure fuel delivery to your engines.

5. Compatibility with Engine Components

While biodiesel is compatible with most diesel engines, certain engine components may require modifications or upgrades to ensure optimal compatibility. Common components that may be affected include fuel hoses, seals, gaskets, and certain types of rubber materials. Grafco Electric specializes in providing customized solutions to address compatibility issues, offering a range of compatible components and materials specifically designed for biodiesel applications.


In conclusion, navigating the challenges of running biodiesel requires careful consideration of fuel quality, cold weather performance, oxidation, fuel contaminants, and compatibility with engine components. Grafco Electric is your trusted partner in the biodiesel industry, offering comprehensive solutions to help you overcome these problems.
