CM400
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.
If you’re into metal music, Sons of Texas is an underrated band. They’re no longer together, but they put out a couple of good albums.
Also check out Cardinal Black, it’s a blues/rock outfit, and really good.
This is the worst iteration of Pop-Up Video I’ve ever seen.
I asked whatever the first ai image generator came up what this would look like.
