Most mower engines are 2-strokes, they're designed to burn oil as lubrication basically, it's added to the gas. You don't need to change the oil. Unless it's a 4 stroke engine (unusual due to size/complexity), or you've got a transmission or some other motorized mechanical behavior.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts: 1
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.
- Posts must be original/unique

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report the message goes away and you never worry about it.

As a 2-stroke myself, I can confirm oil for lubrication is not required
Most mower engines are absolutely not 2 strokes⦠they are 99.99% 4 strokes.
Now strim trimmers are maybe 60/40 2s to 4s.
I wouldnt say most are two stroke. In fact most mowers available for purchase at your local hardware store are going to be 4 stroke if not all of them. 2 stroke lawnmowers are a thing of the past. Everyone wants 4 stroke and self propelling now.
Hmmm, I guess that makes sense. It's been a while since I've bought a gas mower, roughly the late 90's/00's hah, been using electric/battery since then.
I never changed the oil in my mower. Never had an issue, except with the power cord getting in the way.
My neighbor had a crazy old Montgomery Ward tiller, I'd guess from the late 60 or early 70s. I borrowed it once and decided to be nice and change the oil in it since I doubted he ever had. Could not for the life of me figure out how to drain the oil without flipping it over... It's ran for this long on old oil, it'll run for a bit longer!
Flipping it over is often the correct way to drain the oil.
I got my lawnmower about 9 years ago secondhand and have never done any maintenance on it. I'm pretty sure that's how you're supposed to do it.
You nailed it
