The recommended fuel oil mixture for the Homelite HB390 leaf blower is a 50:1 ratio of gasoline to 2-cycle engine oil. This means that for every 50 parts of gasoline, you should add 1 part of 2-cycle engine oil.
Example:
- For 1 gallon (3.78 L) of gasoline, add 2.6 fluid ounces (76 mL) of 2-cycle engine oil.
- For 5 gallons (18.9 L) of gasoline, add 13 fluid ounces (380 mL) of 2-cycle engine oil.
Mixing Instructions:
- Start with a clean, empty gas can.
- Add the required amount of 2-cycle engine oil to the gas can.
- Slowly add gasoline to the gas can, shaking it gently to mix the oil and gas thoroughly.
- Make sure to use fresh, unleaded gasoline with an octane rating of 87 or higher.
- Do not use E85 or gasoline that contains ethanol higher than 10%.
Always mix fuel and oil in a separate container before adding it to the leaf blower's fuel tank. Never mix fuel and oil directly in the leaf blower's fuel tank.
Note:
Using the correct fuel oil mixture is crucial for the proper functioning and longevity of your Homelite HB390 leaf blower. Always follow the manufacturer's recommendations and use high-quality fuel and 2-cycle engine oil to ensure optimal performance and prevent engine damage.
