Does your lawn mower sputter and cough? Does it refuse to start even after you’ve checked the fuel? A good fuel additive can be a lifesaver for your trusty mower. This guide will help you pick the best one.
What to Look For: Key Features of Great Fuel Additives
Performance Enhancers

- Lubricants: These keep moving parts well-oiled for less wear and tear.

You’ll use fuel additives in a few main ways. If you store your mower for the winter, a stabilizer is a must. It prevents fuel from degrading and causing starting problems in the spring. For older mowers or those that seem sluggish, a cleaner additive can help remove built-up gunk. This can make your mower run more powerfully and efficiently. Some people use additives regularly to keep their engines in top shape. This is like giving your mower a healthy diet.
