Pressure washers are essential tools for cleaning surfaces like driveways, patios, vehicles, and more. Among popular brands, Troy-Bilt pressure washers stand out for their durability and performance. However, to ensure optimal functioning and longevity, it’s crucial to use the right type of gas. This article explores the types of gas suitable for Troy-Bilt pressure washers, the impact of fuel quality, and tips for fuel management. Whether you’re a homeowner or a professional, understanding the proper fuel requirements will help you get the most out of your equipment.
Understanding Troy-Bilt Pressure Washers
Troy-Bilt manufactures a range of pressure washers with various cleaning capacities, measured in pounds per square inch (PSI) and gallons per minute (GPM). These machines typically feature small gasoline engines that power a water pump, creating high-pressure water jets for cleaning tasks. To keep the engine running efficiently, the choice of fuel is paramount.
Types of Gasoline Suitable for Troy-Bilt Pressure Washers
Unleaded Gasoline (Preferred)
Troy-Bilt pressure washers are designed to run on clean, unleaded gasoline with an octane rating of 87 or higher. Here’s what you need to know:
- Octane Rating: A minimum of 87 is recommended, but higher octane gasoline can be used if specified by the engine manufacturer. High-octane fuel prevents engine knocking, particularly in high-performance engines.
- Ethanol Content: Ensure the gasoline contains no more than 10% ethanol (E10). Ethanol attracts moisture, which can cause corrosion and lead to difficulties starting the engine or reduced performance.
Premium Gasoline (Optional)
While not required for most Troy-Bilt engines, premium gasoline with a higher octane rating can be used if desired. However, it does not necessarily improve performance or longevity unless specifically stated in the engine manual.
Ethanol-Free Gasoline (Ideal for Longevity)
Ethanol-free gasoline is highly recommended for small engines if available in your area. Without ethanol, the fuel minimizes moisture buildup, preventing potential corrosion and carburetor blockages.
Specialty Fuels
Pre-Mixed Fuels: Available at hardware stores, pre-mixed ethanol-free fuels are designed for small engines and are an excellent choice for occasional use.
Recreational or Marine Gasoline: These are also ethanol-free and can be used in your pressure washer, but they are often more expensive.
Why Ethanol Content Matters
Gasoline with higher ethanol content (such as E15, E85, or Flex Fuel) is not recommended for Troy-Bilt pressure washers. Ethanol is a biofuel derived from corn or sugarcane that absorbs water, which can lead to:
- Corrosion of metal components in the fuel system.
- Separation of fuel layers, creating a gummy residue that clogs the carburetor.
- Decreased engine efficiency, as ethanol contains less energy than pure gasoline.
Always check the pump label to ensure the ethanol content does not exceed 10%.
Fuel Additives: When and Why to Use Them
Fuel additives can enhance the quality and stability of gasoline. Here are some commonly used additives and their benefits:
Fuel Stabilizers
If you store your pressure washer for long periods, fuel stabilizers are essential. They prevent gasoline from degrading and forming varnish or gum, which can clog the carburetor and fuel lines.
Cleaning Additives
Some products clean the fuel system by removing deposits from the carburetor, valves, and injectors, ensuring efficient performance.
Moisture Removal Additives
These additives help absorb moisture that ethanol might attract, preventing rust and corrosion.
Best Practices for Fuel Storage and Handling
Use Fresh Gasoline
Gasoline has a shelf life of about 30 days. After that, it begins to degrade, forming gums and varnishes. To avoid problems, always use fresh gasoline or treat stored fuel with a stabilizer.
Store Fuel Properly
- Use a clean, sealed, and labeled container designed for gasoline storage.
- Store fuel in a cool, dry place away from direct sunlight and heat sources.
- Avoid keeping fuel for more than three months unless stabilized.
Drain the Fuel System After Use
For seasonal storage, it’s good practice to run the engine until it uses all the fuel in the tank and carburetor. This prevents stale fuel from gumming up the system.
Inspect and Clean the Fuel System
Regularly check the fuel tank, filter, and lines for signs of dirt, debris, or corrosion. Clean or replace components as needed to maintain performance.
Steps to Refuel Your Troy-Bilt Pressure Washer Safely
Turn Off the Engine: Ensure the pressure washer is completely turned off and has cooled down to prevent accidental ignition.
Use a Funnel: To minimize spills, use a funnel when pouring gasoline into the tank.
Avoid Overfilling: Leave some space in the tank for fuel expansion. Overfilling can cause leaks and damage.
Clean Up Spills: Wipe away any spilled fuel immediately to prevent fire hazards.
Secure the Cap: Ensure the fuel cap is tightly closed to avoid contamination and evaporation.
Common Fuel-Related Problems and Solutions
Engine Won’t Start
- Check if the fuel is fresh and contains no more than 10% ethanol.
- Inspect the carburetor for clogs caused by old or contaminated fuel.
- Clean or replace the spark plug if necessary.
Engine Stalls or Runs Rough
- Drain and refill with fresh fuel.
- Use a carburetor cleaner or additive to remove deposits.
- Check the air filter for clogs.
Fuel Leaks
Inspect the fuel lines, tank, and cap for cracks or damage. Replace faulty components immediately.
FAQs About Fuel for Troy-Bilt Pressure Washers
Q: Can I use E85 or Flex Fuel in my Troy-Bilt pressure washer?
A: No, E85 or Flex Fuel contains up to 85% ethanol, which is not compatible with small engines.
Q: Is it okay to use fuel with an octane rating higher than 87?
A: Yes, higher octane fuel can be used, but it does not significantly enhance performance unless specified in the engine manual.
Q: What happens if I accidentally use stale gasoline?
A: Stale gasoline can cause starting issues and gum up the fuel system. Drain the tank and carburetor, then refill with fresh fuel.
Conclusion
Choosing the right type of gas for your Troy-Bilt pressure washer is crucial for maintaining its performance and longevity. Always opt for unleaded gasoline with an octane rating of 87 or higher and an ethanol content of no more than 10%. For optimal results, consider using ethanol-free gasoline or treating your fuel with stabilizers to prevent degradation.
By following proper fuel management practices and adhering to the manufacturer’s guidelines, you can ensure your Troy-Bilt pressure washer runs smoothly, efficiently, and reliably for years to come.
