And they're quieter! God I wish my neighbors all had electric mowers. Sometimes it seems like they're invited to all the zoom meetings I attend.

If you never mow and grow insect friendly lawns...you wont ever have to buy a mower...fuck lawns.

My next mower will probably be a lawn service

I expect they do need lubrication from time to time. I just bought an electric mower this year and it's pretty low power, so I predict that any amount of additional friction in the system is going to be too much.

I've owned a car like that. Drove that thing for years until the driver's side door fell off and I parked it.

I'm not sure you can even buy a two stroke lawnmower. Snowblower, maybe.

Yes, you need to have oil mixed with the gasoline in a two stroke, because the area under the piston (where the crankshaft is) creates the vacuum on the upstroke to draw in the next fuel charge. Lubrication of the crankshaft bearings, then, must come from oil that is in the gasoline, either by premixing it, or from an oil injection system.

A four stroke, on the other hand, uses the top of the cylinder, above the piston, to draw in the next fuel charge through an intake valve, and the area underneath the piston is bathed with oil. Over time, that oil (including its additives) breaks down and loses its lubricity, and must be changed for fresh oil.

Never seen a two-stroke mower...

Look at buddy over here with the 1960s lawn boy

Most lawn mowers are 4-stroke.

Only for some engines. Make sure you read the manual and the cap.

I also solved mine but by never changing the oil.

Sharpen/replace the blade. It's cheap and easy to do, and it will cut like a brand new mower.

Also, this is a PSA that you should sharpen your shovel. Makes digging way easier.

Flipping it over is often the correct way to drain the oil.
