In order to run a gas chainsaw
, you need to mix 2-stroke oil with 89 octane or higher gasoline to make your chainsaw fuel. The recommended mixture for optimal performance is 50-to-1 gasoline to oil for all two-stroke engines.
If you don't want to waste time and leave bad fuel in your chainsaw, you can use Husqvarna Pre-Mixed Fuel which gives you better saw performance. Pre-mixed fuel also stays fresh for years so you don't have to waste fuel by emptying your tank after each use.
