🌲 CHAINSAW OWNERS — SOMETHING TO KNOW ABOUT YOUR FUEL THIS YEAR! ⛽️
At Knowles True Value, we want to help our customers understand something that can affect the way your chainsaw runs this fall.
⚠️ 2026 has seen an unusually early transition to winter-blend gasoline.
The EPA issued a special waiver on August 20, 2026, allowing the transition to winter gasoline to begin September 1st, earlier than the normal end of the summer fuel-control period.
🔧 Why does that matter to your chainsaw?
Winter gasoline is generally formulated to be more volatile than summer gasoline. In a 2-stroke chainsaw, changes in fuel volatility can affect:
• Starting characteristics
• Throttle response
• Idle quality
• Fuel vaporization
• Carburetor mixture behavior
• How the saw responds under load
If your chainsaw seems to be behaving differently than it did earlier this summer — harder starting, different idle, hesitation, or a change in how it pulls under load — fuel can be one of several things worth considering.
That doesn’t necessarily mean there is anything wrong with your saw. Fuel formulation, temperature, storage, oil mix, carburetor adjustment, and the condition of the saw can all play a role.
🌲 Before you start adjusting your carburetor, bring your saw by Knowles True Value and let us help you figure out what’s going on.
We want to keep your equipment running right, cutting strong, and ready for the season.
