Depending on the lawn mower I use 3/8" ratchet that fits into the square plug in bottom or a good adjustable wrench.
Hope this helps

what grade of oil on this engine
For a Craftsman Platinum 7.25 lawnmower, you typically need about 20 ounces of oil for a complete oil change. It's essential to check the owner's manual for the specific model to confirm the exact oil capacity, as it may vary slightly. Always use the recommended oil type for optimal performance.
Depending on the model of the Craftsman lawnmower, there is either an oil plug underneath the deck of the mower which needs removed to drain the oil or the lawnmower needs tipped on it's side to allow the oil to drain out through the oil cap area. Once oil has drained you will want to refill the oil until the dipstick registers "full".
You need to have a special filter wrench to do it, which is a cup-type as opposed to a band-type. Filter is cartridge not spin-on.
Use an open end wrench.

It means some type of routine service is required, usually oil change.
Commonly 30W of SG or higher rating
Using 2-stroke oil in a lawnmower is not recommended unless the mower is specifically designed for a 2-stroke engine. Most lawnmowers operate on 4-stroke engines, which require a different type of oil, typically SAE-rated motor oil. Using 2-stroke oil can lead to improper lubrication, increased emissions, and potential engine damage. Always consult the owner's manual for the appropriate oil type for your lawnmower.
