I used to change my oil in my truck per season, and whatever I dumped went into the lawnmower for that season, as did the used filter.
That mower is now 11 years old, and the engine still hums, powers still there, the cutting deck rotted away, but it still hauls a 6 ft tractor trailer full of limerock when the road washes away.

I do the same thing. I've been using spent 0w-20 and pennzoil HM 5w-30 after it leaves the truck and my push mower still runs as good as the day it was bought and its in its 5th year.
I'm not gonna knock super tech at all. It's great oil whether it's in a vehicle or yard equipment
I have seen riding tractors and push mowers run exclusively on everything from used HMMWV 15w40 to used Turbine oil out of a tank, to simple CLP gun oil.
Most of the time the mowers didn't die due to the fluids, but to inexperienced city raised spoiled kids that never mowed a day in their life, apparently, some people believe Diesel, JP8, and kerosene can go into a lawn tractor.
I've gone to classes for B&S engines, ive rebuilt quite a few in my old barracks room while still in (Some even for other units ive never even been a part of)
Awards were great, but when another units CSM talks to your unit and you get days off, worth it in my opinion.
If you run 0w30 or thicker in your vehicle, theres no reason not to reuse it. Mower oil has less detergents than PCMO, additives and detergents wear over time in your engine, some to the same exact spec as NEW mower oil.
Use it with confidence. If its a Briggs with a filter, normally your Purolator 20195s, fram 3600s (and others that use fram numbering) will work. not always but mostly.
