Now that I think about it, it was probably before the pandemic. 🤔
Genuine question as I haven’t actually thought about this, how does that work when you don’t have a winter? Where I live it doesn’t get below 40° ever, or above 85°. Those are literally the overnight low in Feb, and midday high in Aug/Sep. Do I still need to drain, or just treat it like changing the oil in my car? I.E.: Every 6 months or 3500 miles, whichever comes first.
Like u/possiblylinux127 said, any time you’re not going to use it for more than a month or two, it’s best to drain the fluids. Oil is less important than gas, and you can leave gas in it as well if you add a stabilizer to it.
Personally, I wouldn’t use gas stabilizer for more than one season, but I know many who use it every year with no problem. Just make sure you run the motor with the stabilizer for a few minutes before you store it so the gas in the carburetor doesn’t gum up.
As for oil, I tend to only change it when it looks darker than a piece of burnt toast I’d still be willing to eat. I know that’s vague, but it’s how I do it.
Ideally, you should be using nonoxygenated gas for your mower, in which case stabilizer is unnecessary. The ethanol is what gums up carbs.
