Consumer Reports Shares The Lawn Mower Maintenance Mistake You Don't Want To Make

On the surface, a lawn mower seems like a pretty basic appliance. You start it up, cut the grass, empty the bag, and tuck it away. Done, right? Not quite. Whether you're hauling the lawn mower out for the first time in the spring or pulling it off after a few weeks, there's one maintenance mistake Consumer Reports wants you to remember: changing or topping off the oil.

Why is this lawn mower maintenance task so crucial? Changing the oil is key to keeping it running at peak performance for years to come and helps prevent mower damage. It's generally recommended to change the oil annually, but Consumer Reports recommends checking the oil levels at the beginning of the mowing season, even if you did so when preparing for winter.

What happens if you run the mower that's low on or has no oil? "Running it for a minute or two is unlikely to cause damage," Mike Visconti, Consumer Report's director of lab operations explains in Consumer Reports' article. "It could lead to problems, though, if you use it to cut for more than a few minutes." These problems include overheating, warping, or even engine failure, meaning it's absolutely worth taking an hour or two to top off or swap out your lawn mower's oil.

The first thing you should do when checking and refilling your lawn mower's oil is always to check the manual. Always. Each machine is created differently, so following the manufacturer's instructions will help ensure your mower keeps buzzing for a long time.

However, there are some guidelines to keep in mind through the process. First, the oil itself is your best gauge. Use the dipstick to check the level and consistency. If it looks dirty or has scraps floating in it, it's a sign you need fresh oil. Next, it's much easier to drain the oil if the engine is slightly warm, so turn your lawn mower on for a brief moment, then turn it off and unhook the spark plug to make sure it doesn't turn on inadvertently. Spread a tarp outside, then remove the drain plug and let the oil run out into a designated oil pan or other safe container. Once it's empty, replace the plug and add new small engine oil. Check your manual for exact specifications. Check the dipstick to make sure the oil is at the right level before starting the mower. The best way to dispose of old lawn mower oil varies by where you live. Check with your local waste and recycling center for details.

Checking the oil isn't a one-and-done task. It's important to keep an eye on the level and consistency throughout the mowing season. Your owner's manual will have more details, but plan on checking in on it every few weeks or so to keep your mower running smoothly.
