The Craftsman Model 358.351810 chainsaw requires a fuel mixture of unleaded gasoline and 2-cycle engine oil. The specific ratio of gasoline to oil is 40:1. This means that for every 40 parts of gasoline, you should add 1 part of 2-cycle engine oil.
IMPORTANT:
- Always mix fuel in a well-ventilated area.
- Avoid spilling fuel, and keep it away from open flames and heat sources.
- Use only fresh, unleaded gasoline with an octane rating of 87 or higher.
- Do not use E85 or gasoline containing more than 10% ethanol.
- Use a 2-cycle engine oil specifically formulated for air-cooled engines, such as Stihl HP Ultra or Husqvarna XP.
- Never use automotive oil in a 2-cycle engine, as it can damage the engine.
Always follow the manufacturer's recommendations for fuel mixture ratios and the specific type of oil to use. Improper fuel mixtures or the wrong type of oil can cause engine damage.
