Q&A: Fuel stabilizers for outdoor power gear

Consumer Reports News: October 20, 2010 06:16 PM

I’ve heard about the need to protect your power equipment by adding fuel stabilizer. But is it okay to add stabilizer to gasoline containing oil, for a 2-cycle engine?

All gasoline-powered engines, including two-cycle, benefit when you add fuel stabilizer to the gas. This is true even if the oil you’ll mix with gas for a two-cycle engine includes some stabilizer, as many do.

It’s best to add the appropriate amount of stabilizer to the gasoline first before adding the correct amount of two-cycle oil. We recommend you add the stabilizer to the gas in its can before fueling up.
