Hmmm. I've never treated any fuel in any of my lawn equipment and never had an issue starting them.
My push mower is a Honda that is easily 20 years old and starts on the first pull EVERY time. It's due for it's 10 year oil change. Plug change? Maybe another few years. Walmart mower? I'll pass. Tractor, chainsaw, weedwacker, leafblower, never an issue with any of them.
I must be walking around lucky.
