Use regular Stihl 2 cycle oil. You mix it 50:1.
The Stihl MS 460 Magnum chainsaw requires a gas-to-oil ratio of 50:1 for its fuel mixture. This means you should mix 2.6 ounces of Stihl 2-cycle engine oil with one gallon of gasoline. Always use high-quality, unleaded gasoline and ensure proper mixing for optimal performance and engine longevity.
The Stihl MS250 chainsaw requires a gas-to-oil mixture ratio of 50:1. For 5 liters of gasoline, you would need to mix in 100 milliliters of 2-stroke engine oil. This ensures optimal performance and lubrication for the chainsaw’s engine. Always use high-quality oil specifically designed for 2-stroke engines.
32:1 or 40:1 with high quality 2-stroke oil mix would be fine. http://store.chainsawr.com/
