Reclaimed Oil for push mower.

Mostly excellent scores, except for the Valvoline synthetic blend at 17.99. When Kirkland full syn is on sale, it is 15 and change.
Regular price of the Valvoline Premium Blue diesel rated oil is close to $30.

Kirkland is same as Supertec - Warren makes both.

I use Supertec - Warren is good to go but nothing special.
 
My Simpson pressure washer with a Kohler engine has two drain plugs, one on each side -

But the oil in the pump never gets changed - has no drain plug.

I am not suggesting you don't know what you have - but that is strange - what model do you have?

Mine looks like this. Except it is 3,300 PSI

Mines cobbled together with a rebuilt high compression gx390, go-kart intake, ignition advanced about 8 degrees and a 4.4gpm pump.
 
Oops I did it again. I've sequestered a special oil catch pan for car and truck oil. I use it, wipe it off put it in a trash bag to keep any dust off it, it only catches car and truck engine oil. A pressure washer blast around the drain plug to further reduce contamination and I use my dirty catch pan to catch the oil from unscrewing the oil filter.
Since it's lawnmower fixing season again, been using my used car oil to top off and flush the oil in neglected mower engines.
Can't beat free 99 a gallon oil when it's only going to be ran for maybe 10 minutes.
 
Bought a ford explorer from my wife's brother. Needed an oil change. Man that oil was black. Not suitable for reuse.
Went straight into the "combustion grade" oil jug.
 
I doubt it....😀
Been working on mowers since I was 12 years old, it appears most people don't change the oil in their mowers until there's something wrong with it.
Most of the mowers that do get the oil changed their owners take it to a small engine repair shop and they do it.
I've got a nice garage kept Craftsman 48 inch, Briggs v twin 24hp riding mower with 202hrs on it, i don't think they ever changed the oil, probably only added oil when the low oil shutdown kicked in. That engine is toast.
I'm pretty sure I sold blades to them 3 years ago and the oil was bitog black and barely on the dip stick then.
 
My dad gave me a 4 stroke LawnBoy that consumes oil and needs topped off before each use. I can top it off and check it a week later and i swear the level has gone down. (No leaks on the ground.)

I’m starting to use used oil in it. 🤫
 
Well I found 2 more uses for my reclaimed oil. My second oldest air compressor I got used some time around 2011 got full of water. It normally stays on my big trailer and a recent storm blew the cover off enough to expose the air compressor pully. Well I guess the shaft seal is a gonner because it's got a bunch of water in it.
I drained everything out I'll refill it with reclaimed oil run it and dump it as many times as it takes till it comes out clear with no water.
I actually want detergent oil for this because it will try to emulsify the water and flush it out faster.
I'll take it apart and see if I can find a new oil seal seal later. Hopefully there's a number on it. But I need it today.

2nd new use. The rear diff oil came out of my BIL ford explorer opaque brown.
Filled it up with reclaim oil, drove it easy for 9 miles and dumped it, as opposed to filling it up with $10 worth of my cheapest clearance gear oil. Now I can save the clearance gear oil for my brush shredder and makes it less likely, well 2qt less likely I'll have to buy gear oil at full price.

I'm working on generation 2 reclaim oil. More on that later. It will involve actual testing beyond that of the testing I do when I test most of the oil changes that come out of my wife's car.
 
Reuse used oil? Lets rinse and reroll those condoms also, they look fine.:ROFLMAO:
Yeah I'm using it as flush oil.
Reclaimed oil saved 44oz of new compressor oil or pcmo flushing out my air compressor that filled up with water, then saved 2qt of gear oil flushing a ford 9'' that had opaque brown metalized oil in it and about a quart filling and flushing out a lawnmower that had metallic bitog black looking oil in it. So that's at least gallon of new oil it saved me just this weekend. It's also one gallon less waste oil to have to deal with.
If I'm only running it for 5 to 20 minutes and dumping it what's it going to hurt?
 
We make a few hundred gallons of flush oil a month at work. Everytime a different product is pumped through a line, about 5 gallons is written off for flush.

Like I fill a 15w40 tank and next is a 0w30 tank, line is flushed. Or in some trucks only have 1 pump so might be pumping ATF, then engine oil, hydraulic oil, etc.

Anyhow, it provides me with heat. I've never considered using it in anything.

When I helped out at a small engine shop I fixed DOZENS of oiling systems on saws that people decided running used engine oil for bar lube made sense.
Not only would it plug everything in the oil system or kill the pump, but fling everywhere and plug the cooling fins, and eventually seize the engine.

Maybe if it was filtered and some sort of tackifier added it'd be ok. But the proper oil is $10 a gallon and most don't use but a gallon or 2 a year anyhow.

I've been using really old SA rated 30wt, 40wt, first edition SL rated 10w-30, first edition SM rated 30wt and really old ATF mixed with any of those oils during the winter for years now. Most recently I've added 2.5 gallons of ancient SH rated 30wt oil to bar oil stash.
For right now my saw bar oil and break in oil is just really old but still virgin motor oil. At the moment I have plenty of it and I'll probably use it all in saws mostly and new engines and it will be gone by early next year unless I discover more.
It flings everywhere because the pump is actually able to pump enough of it and keep the bar cool.
Project farm did a test of saw oils. The motor oils and repacked motor oil as saw oil did the best.

When used oil clogged everything up I bet they used oil that ran down the dirty oil filter and ran down the dirty oil pan and into an even more dirty catch pan that had nasty oil from lawnmowers, differentials and whatever dumped out of oil filters in there too. Probably didn't even try to filter it then wonder why it clogged up their saw.

My reclaimed motor oil starts off by cleaning around the drain plug. I pull the drain plug let the first half quart or so of oil fall into the dirty oil catch pan, then catch the oil I want to save in an oil jug that only ever had new oil in it prior to that moment.
But what about the oil that comes off the oil filter? Straight into the dirty catch pan with the combustion grade oil, don't even try to save what runs down the filter or what was in the filter.
Since stuff settles out of my cleanest reclaimed oil I dump the last half quart into my combustion grade oil jug, or that reclaimed jug gets marked to be combustion grade.

I used to use used motor oil for my chainsaw way back in the day until my Stihl dealer yelled at me for doing that and have been using chainsaw bar oil ever since.

If care is used to keep it clean... like not grabbing a drain pan that got 1/4" of goo, leaves and dead bugs it'll work, but it makes a mess.

Couple that with average Joe running the chain to way, way, way beyond dull so the saw is doing 13k rpm for 5 mins making 1 cut, an even bigger mess.

My processor Lunesta bar with hydraulic oil from its hydraulic system. Works fine but needs pressure washed every few hundred hours from the mess.
 
I guess I can't really see the point of reusing oil in a push mower that takes maybe 20 oz.
The savings just aren't there and the amount of effort involved certainly outweighs any savings involved in using this inferior product.
I'd file this one under either the penny wise and pound foolish or the false economy index.

I'm using it as will it even start and flush oil. The thing that happens at least every week is I get a mower in. Idk if it even starts and it's really low on oil. So do I dump perfectly good oil in a possible junk mower that might not start or free used oil?
Then say it does start and runs long enough to get warm I dump it and refill with used oil to test it out for a bit and see if it's even worth keeping. That's the flush.
I could put fresh oil in for the flush but as soon as I start again it's blacked out and I'd still end up changing it again.
This way I only put new oil mowers that I know are good.
My mowers get new oil.
Also used reclaim oil to flush out an air compressor that was full of water.
Then used it to flush out a rear diff that had opaque brown metalized oil in it for who knows how long.
Most of all I have less gallons of used oil to get rid of.

When they burn up I bet that what usually does it.
