How often should I use a Subaru fuel additive?
Subaru vehicles are known for their reliability and performance, but like any car, they require proper maintenance to keep running smoothly. One common question Subaru owners ask is how often they should use a fuel additive. In this article, we’ll explore the purpose of fuel additives, their benefits, and how frequently you should use them to maintain your Subaru’s performance.
What Is a Fuel Additive and Why Is It Important?
Fuel additives are chemical compounds designed to improve the quality and efficiency of your fuel. They can help clean your engine, reduce carbon buildup, and improve fuel economy. For Subaru vehicles, using a fuel additive can be particularly beneficial in maintaining the health of the fuel injectors and combustion system, especially if you frequently drive in stop-and-go traffic or use lower-quality gasoline.
How Often Should You Use a Subaru Fuel Additive?
Subaru recommends using a fuel additive periodically to keep your engine running at its best. Here are some general guidelines:
- Every 3,000 to 5,000 miles: Adding a fuel additive during your regular oil change interval is a good practice. This ensures that your fuel system stays clean and free of deposits.
- Before long trips: If you’re planning a road trip, using a fuel additive beforehand can help optimize fuel efficiency and engine performance.
- When using lower-quality fuel: If you’ve had to fill up with gasoline from an unfamiliar or lower-quality station, a fuel additive can help mitigate potential issues caused by impurities in the fuel.
It’s important to note that overusing fuel additives can be counterproductive. Always follow the instructions on the product label and consult your Subaru owner’s manual for specific recommendations.
Benefits of Using a Fuel Additive
Regular use of a fuel additive can provide several benefits for your Subaru, including:
- Improved fuel efficiency: By cleaning the fuel injectors and combustion chamber, additives can help your engine burn fuel more efficiently.
- Reduced engine deposits: Additives help prevent carbon buildup, which can negatively impact engine performance over time.
- Enhanced engine performance: A clean fuel system ensures smoother acceleration and better overall performance.
- Prolonged engine life: Keeping your fuel system clean reduces wear and tear on critical engine components.
Choosing the Right Fuel Additive
Not all fuel additives are created equal, so it’s important to choose one that’s compatible with your Subaru. Subaru offers its own branded fuel additive, which is specifically formulated for their vehicles. Alternatively, you can opt for high-quality aftermarket products from reputable brands. Look for additives that are designed to clean fuel injectors and improve fuel economy.
Conclusion
Using a fuel additive is a simple and effective way to maintain your Subaru’s performance and longevity. By incorporating it into your regular maintenance routine—every 3,000 to 5,000 miles or as needed—you can enjoy a smoother ride, better fuel efficiency, and a healthier engine. If you’re unsure about which product to use or how often to apply it, don’t hesitate to consult your trusted auto service provider or refer to your vehicle’s owner’s manual.

Frequently Asked Questions
How often should I fuel injection clean my Subaru?
We may recommend that you bring your model in once a year for a cleaning, but when in doubt, it's always best to speak with one of our service providers for exact information pertaining to your particular Subaru model.
Should I use fuel injector cleaner regularly?
There is no set answer as to whether or not fuel injectors need periodic cleaning that will apply to all cars and all situations. But using a Top Tier gasoline with the occasional bottle of fuel-injector cleaner should work to keep your injectors clean, and perhaps even to cure some mild rough-running issues.
Does my Subaru really need premium gas?
If you drive a Crosstrek, Forester, Outback, Legacy or Ascent, your vehicle is designed to run on 87 octane, or regular fuel. Performance Subaru models – the WRX, WRX STI and BRZ – have a premium fuel requirement, but even with those vehicles, check your manual for information on which fuels are appropriate.
Can you put too much gas additive?
Can fuel additives damage your vehicle's engine? Yes, if you use them improperly or use them too much.
How often should you use a Fuel Additive?
So, how often should you use them? It's recommended by manufacturers to add fuel injector cleaner to your vehicle roughly every 1500 to 3000 miles, or as often as every oil change if you're using top-tier fuel. However, this guidance isn't one-size-fits-all.
Do subarus need fuel injector cleaner?
While fuel additives can offer benefits, they are not always necessary for every Subaru owner. Consider using fuel additives when: You have an older vehicle with carbon buildup or fuel system issues. You plan to store your Subaru for an extended period.
Can you put too much fuel additive?
Too Much of a Good Thing Can Be Bad
If you're losing lubricity, don't over-treat. Adding too much of a lubricity improver can react with other various contaminants already in your fuel to cause a different fuel problem—clogged filters.
How long do Subaru injectors last?
50-100k miles
Subaru fuel injectors have been know to last much longer than 50-100k miles. There is no service interval at which the injectors "need" to be replaced as part of any maintenance schedule.
When to add Subaru Fuel Additive?
Subaru recommend the use of their Fuel Additive every 6,000km to help reduce combustion chamber deposits, therefore reducing the engines octane requirement.
What are the cons of fuel additive?
While these additives enhance fuel performance, quality, and safety, some have potential downsides. For example, ethanol can cause material compatibility issues in older vehicles, while metal-based additives like MMT and ferrocene can increase particulate emissions and spark plug fouling.
