What You'll Learn
Larger fuel injectors don't always increase fuel mileage
It is a common misconception that larger fuel injectors will increase fuel mileage. While it is true that larger injectors can lead to more power, this does not necessarily translate to improved fuel efficiency. The relationship between fuel injector size and fuel economy is complex and depends on various factors.
Firstly, it is important to understand that bigger injectors do not always result in more fuel being used. The amount of fuel sprayed is determined by the injector pulse width or "on" time. For example, a larger injector running a shorter pulse width may spray the same or even less fuel than a smaller injector with a longer pulse width. Therefore, simply increasing the size of the injector does not guarantee increased fuel usage or decreased fuel economy.
However, it is true that larger injectors can provide more power, which can indirectly lead to improved fuel efficiency. A more powerful motor doesn't have to work as hard, and as a result, you may not need to press the throttle as hard in certain situations. This reduced throttle usage means less fuel is being sent to the motor, leading to potential improvements in fuel mileage.
That being said, the benefits of larger injectors on fuel economy are not always significant, especially when upgrading from a set of injectors that are already in good working condition. In such cases, the existing injectors are likely already operating efficiently, and switching to larger injectors may not yield noticeable improvements in fuel mileage. Additionally, the quality of the injector being installed is crucial. Modified or remanufactured injectors may have worn-out parts that are not working efficiently, which could potentially lead to a drop in fuel mileage despite the larger size.
In conclusion, while larger fuel injectors have the potential to improve fuel mileage in certain scenarios, it is not a guarantee. The actual impact on fuel economy depends on various factors, including the condition of the existing injectors, the quality of the new injectors, and driving habits such as how heavily the accelerator is pressed. Therefore, it is important to consider the specific circumstances and not assume that larger fuel injectors will always result in increased fuel efficiency.

Injector on time and pulse width can affect fuel usage
Injector pulse width and "on" time can have a significant impact on fuel usage. Injector pulse width refers to the amount of time the injector is open and spraying fuel into the engine. The longer the injector stays open, the more fuel is delivered to the engine.
When discussing injector pulse width, it's important to distinguish between large and small injectors. Large injectors, such as those found in high-performance engines, have a higher flow rate and can deliver more fuel with each pulse. In contrast, small injectors found in standard vehicles have a lower flow rate and deliver less fuel with each pulse.
The injector pulse width can be adjusted to control the amount of fuel delivered to the engine. For example, when an engine is idling or running at low speeds, the injectors will operate at shorter pulse widths, resulting in shorter spray times and less fuel delivery. On the other hand, during high-performance driving or when the engine demands more fuel, the injectors will operate at longer pulse widths, delivering more fuel to meet the engine's requirements.
It's worth noting that the relationship between injector size and pulse width is not linear. As injector size increases, the operation becomes more complex, and the fueling can be subject to larger errors in the low injector pulse width (IPW) range. This is why it's crucial to have a basic understanding of modern fuel injector technology before making any adjustments.
Additionally, the quality and condition of the injectors play a significant role in fuel usage. Upgrading to premium injectors with all new parts can improve fuel economy, as they perform optimally and efficiently. However, simply increasing the size of the injectors may not always result in better fuel mileage. It is recommended to assess the condition of the existing injectors and consult with experts before making any modifications.

New injectors can improve fuel economy
Upgrading from old, worn-out injectors to new injectors with all new parts can lead to an increase in fuel economy. New injectors perform optimally and efficiently, with improved spray patterns and better fuel atomization. This means that the engine can more precisely control the air-fuel mixture, resulting in more efficient combustion and improved fuel mileage.
However, simply increasing the size of the injectors may not always lead to better fuel economy. While larger injectors can be tuned to run with less pulse width, spraying the same or less fuel than a stock injector, the tuning capabilities are limited by the mechanical abilities of the injector. Therefore, the benefits of larger injectors may be offset by other factors, such as the condition of the previous injectors and driving habits.
The quality of the injector is also important. Some companies modify and test used injectors, but the working parts may still be worn out, leading to decreased efficiency and fuel mileage. It is recommended to install new stock-sized injectors if your current injectors are worn out, rather than upgrading to larger injectors solely for the purpose of improving fuel mileage.
Additionally, maintaining the cleanliness of the fuel injectors is crucial for optimal performance. Over time, the engine's throttle body can collect debris, leading to a rough idle and decreased fuel economy. Regular cleaning, either through the use of fuel injector cleaners added to the fuel or professional cleaning services, can help maintain the efficiency of the fuel injectors and improve fuel mileage.

Worn injectors can decrease fuel mileage
Upgrading to fresh injectors, such as Premium Reman Power Stroke Injectors, can improve fuel economy by ensuring that all parts are new and functioning optimally. However, simply increasing the size of the injectors may not lead to better fuel mileage if the previous injectors were already working efficiently. It is important to note that the benefits of larger injectors can be limited by their mechanical abilities, and tuning adjustments may be required to maintain good fuel mileage.
The quality of the injector is also crucial. Some companies modify and test used injectors, which may have worn-out parts, leading to decreased fuel efficiency. It is recommended to opt for new stock-sized injectors if your current injectors are worn out, as they will improve fuel mileage without compromising performance. Additionally, excessive acceleration, such as performing burnouts, can significantly impact fuel mileage, regardless of the injector size or condition.
In summary, while injector size can influence fuel mileage, it is more important to focus on the condition and quality of the injectors. Worn injectors can decrease fuel mileage, and upgrading to new, efficient injectors of the appropriate size can help improve fuel economy. However, it is also essential to consider driving habits, as aggressive acceleration can counteract any gains made by upgrading injectors.
