Comparison Guide: CT500 vs FN608 Fuel Injector Cleaner & Tester

The fuel injector is the “heart” of the engine’s fuel system. It precisely sprays atomized fuel into the cylinders to ensure complete combustion and smooth power delivery.

However, over time, deposits such as gum, sludge, and carbon can accumulate inside the injectors. As a result, fuel injection may become uneven or even blocked. This can cause various engine issues, including vibration, unstable idling, poor fuel atomization, reduced combustion efficiency, higher fuel consumption, weak acceleration, and even starting difficulties.

At this point, a professional fuel injector cleaning and testing machine becomes essential. It not only helps diagnose injector performance but also effectively removes internal deposits, restoring proper fuel spray and bringing the engine back to its optimal condition.

In this article, we will compare two popular models — AUTOOL CT500 and AUTOOL FN608. By understanding their differences in functionality, application, and performance, you can more easily determine which one best suits your specific needs.

Summary

The CT500 fuel injector cleaner and tester is ideal for small workshops and individual car owners. It focuses on affordability and practicality, supports up to 6 injectors, covers daily testing needs, and offers great value for money.

In contrast, the FN608 fuel injector cleaner and tester is positioned as a high-end professional tool. It supports up to 8 injectors, features a heating function for cleaning fluid, a dual-pump design, and a wider voltage compatibility range. It provides greater flexibility and efficiency, making it perfect for large repair shops and professional technicians.

Overall, if you value cost-effectiveness and basic functionality, the CT500 is an excellent choice. However, if you seek high performance and professional-grade testing, the FN608 is definitely worth the investment.
