Frequently Asked Questions

What is the purpose of an oil separator in the fuel system?

While technically part of the PCV system, an oil separator (or catch can) prevents oil vapor and blow-by gases from re-entering the engine's intake manifold. This keeps the intake tract clean, especially in direct-injection engines, improving efficiency and preventing carbon buildup.

How often should I replace my automotive fuel filter?

The replacement interval varies significantly by vehicle. Generally, gasoline filters should be replaced every 30,000 miles, while diesel filters often require replacement more frequently, sometimes every 10,000 to 15,000 miles, due to the critical nature of diesel fuel cleanliness.

Are fuel saver devices effective?

The effectiveness of plug-and-play fuel saver devices like the one listed (B0G2LP2QP6) is often debated. While some users report minor improvements in MPG, results can vary widely based on the vehicle type, driving habits, and the device's specific technology. They are generally considered a low-cost experiment rather than a guaranteed performance upgrade.
