Any utility in used motor oil?

Is there any utility in saving used motor oil from diy oil changes? I know heating oil companies refine that stuff.
motojesus@reddit
mix in a little diesel , grab a paint roller and pan, and roll it on any trailer bed made of wood, do it once a year.
Jugzrevenge@reddit
Put some diesel in it and coat fence posts or wood that may rot.
Sigurdyr@reddit
Curious as i've never handled diesel, do you add diesel to help thin the oil out temporarily to help it penetrate deeper into the wood?
Funny if so, cuz I was reading a research paper about preserving wood this way and they essentially just assumed it was hillbilly superstition that diesel would help somehow. Scientists are so dumb sometimes.
For instance you can find tons of papers about the Asian tradition of blackening ones teeth, apparently people who do this will tell you its to prevent rot and strengthen the gums. Yet even among those researching it it was viewed purely as self mutilation and it took quite a lot of digging to find that recently somebody finally studied the effect this had on steptococcus mutans in vitro and durr hurr it worked! I'm def gonna try this soon, thinking i'll just do my rear molars so i don't look gross

I just pour the oil on straight, am I gay or is that fine
Sigurdyr@reddit
I've read on reddit somewhere that if you brush it on on a nice warm sunny day it'll absorb right in and supposedly never leach out. I've also found a couple research papers about brushing it on hot followed by soaking it in cold oil helps it to penetrate better. just spent way too long trying to dig them up, coulda swore it was bookmarked
Mala_Suerte1@reddit
Straight oil works fine.
Opening-Future3991@reddit
What about gay oil, askin for a friend
Mala_Suerte1@reddit
Are you melting down gays to make gay oil?
Opening-Future3991@reddit
No I boil them and then put them in a presser
Ashley_Sophia@reddit
I hope you identify as gay. It makes your joke 1 million times funnier. Hahahaha you rock! 🍻♥️🌈🦄

Change it late enough and its full of diesel anyway
MarzipanOverall5803@reddit
It depends how you’re putting the oil on the straight
Electrical-Title-698@reddit
I believe the diesel is only to thin it out a little bit

Out of curiosity, what should the ration of each in this mixture be?

Sigurdyr@reddit
One method of rust prevention i've seen on youtube is getting the metal hot then dipping it in used oil or various other things to blacken it. I've seen a handful of research papers about refining used oil and it never sounded incredibly complicated.
Some mention flocculating contaminants out with sodium silicate, but sodium sillicate will total an engine from what i've read so i'd steer clear of that.
Cute-Consequence-184@reddit
Old farmers trick is to add it to sand and when you bring your garden tools in, shove them into the sand to get all the damp dirt off. It kept them from rusting. They could also just be stored in the same all winter with the metal soaking up the oil.
Miss_Anne_Throwpick@reddit
I was just coming here to say the same thing! I've got a couple old cat litter buckets full of sand and old motor oil in my shed with various tool handles sticking out of em. Motor oil for the head, mineral oil for the handles. Shovels, axes, adzes. That and a whetstone keeps 'em pristine
Cute-Consequence-184@reddit
Not too many people do this these days but it works so well.
How else would your tools last 50+ years.
Ashley_Sophia@reddit
We just buy more and herein lies the problem, no! 💖
Cute-Consequence-184@reddit
Absolutely the problem. And most of the garbage these days will not lest half as long as the old, used tools already 50+years old.
Sporesword@reddit
Who else here instinctually thinks 50 years ago is around 1930-1950?
HonestMeatpuppet@reddit
YUP! 50 years ago my grandfather was storming the beach in Normandy. He died 33 years ago at the age of 71 but I SAID WHAT I SAID 😂
Cute-Consequence-184@reddit
LMAO 🤣🤣🤣🤣, ME!
No-Comedian3768@reddit
Especially the Harbor Freight stuff made in China...
Miss_Anne_Throwpick@reddit
Some of my tools are that old, if not older! I have a few of my granddad's yard tools and hand drills that are still in perfect shape, minus where the metal's worn down a quarter inch or more from use. Some of 'em look like they could've been HIS granddad's tools!
Cute-Consequence-184@reddit
I buy them used and stick them in the sand for a few weeks then go back and start in with the navel jelly for any leftover rust then hit with wire brushes then sharpen again and then back into the oil.
I get lots of old tools cheap because no one knows how to deal with rust.
Miss_Anne_Throwpick@reddit
Naval jelly! I do pawn shops and yard sales for a lot of my tools, but how have I never heard of naval jelly before? I've always used a wire brush and some PB Blaster for the minor rust, and a redneck electrolysis setup for the really bad cases. That's how my uncle restores old wood stoves for a living, but it's a lil bit electrocute-y if you're not careful.
HonestMeatpuppet@reddit
“Redneck electrolysis setup” 😅 Found a 125lb Peter Wright anvil at a yard sale that must have been used as a lawn ornament for 30 years. It looked pretty gnarly to say the least. Got a storage bin and filled it up with water and washing powder. 12V battery and a couple of cheap dinner forks later and she was as good as new.
Cute-Consequence-184@reddit
So get some navel jelly, it works wonders
No-Comedian3768@reddit
Try vinegar, it does the trick too!
Wilson2424@reddit
I love a good vinegar soak for old rusty axe heads
InconspicuousWarlord@reddit
Forgive my ignorance, but wouldn’t that leave oil on your tools when you’re gardening, and therefore leave oil in your garden where you grow things to eat?
No-Comedian3768@reddit
if you have another bucket with sand, no oil, stick the tool in before you work in the garden, all residue will be gone and your organic garden will keep you healthy as a fiddle
Ashley_Sophia@reddit
OMG thanks for sharing. All this old knowledge is getting lost.... 🍻
enginenotfound@reddit
My dad used to stain the deck with it
No-Comedian3768@reddit
Slippery when wet??
enginenotfound@reddit
Not once it gets settled in. It had a cover over it so never exposed directly to rain except the edges
Finkufreakee@reddit
Fire stater when you're burning trash.
grayson101@reddit
Tons of people use it for firearm lube
Dangerous-Kick8941@reddit
I save some up every now and then, add some pump gas to thin it out. The gas also allows a lot of the sludge and stuff to drop out. I add that 5 to 10 gallons at a time to my tank and fill it the rest of the way up with pump diesel.
Open-Host300@reddit
I saw a YouTube video where a guy made a burner to heat his garage. I don’t remember the details but I’m sure you can find it
Chestlookeratter@reddit
Depending if you have neighbors you could make a pulse jet to burn trash or heat water for steam. Could get an oxygen generator off Amazon then combine that with the oil spray and run a hit or miss motor or a diesel genset. Could also mix it with acetone and use it as undercoating and metal protection on farm equipment
Sporesword@reddit
Find an old diesel engine to throw it into, it's fuel now.
GarthDonovan@reddit
There was this machanic I knew of that heated his shop all winter long with used motor oil from all the "free" oil he got from oil changes. Converted an oil furnace. Apparently, it burns a lot hotter, so you need a sacrificial metal plate that needs to be changed from time to time. probably saved him 10s of thousands in heating bills over his career..
Poor man's pressure treaded lumber. Fence posts, drill a small hole on an angle a few inches up from the ground line and fill it up with oil and cap it with a wood plug. Coat the fence. A family member did the fence coat used motor oil a diesel. You wouldn't know it wasn't a store bought stain until he said what it was
Jose_De_Munck@reddit
You can feed old diesel engines with that. Sure, you need a filtering of the metal particles, and some cleaning and dilution with regular diesel, but it makes a great post SHTF fuel. Non electronics sissy diesel engines of course.
woodslynne@reddit
lots of ppl use it in chainsaws here for the bar oil. Wears out the bar and chain faster I would think I don't cuz they cost too much to replace but....Y.Good for starting fires. I'll use some to burn brush when it's just too wet.You could prob. trade it. Besides gas will run out then chainsaws will be useless.
WittyTree3760@reddit
I coat my utility trailer with used oil. I wait for a three day dry window so it can bake in. NW Florida is pretty hard on pressure treated wood but the oil coating does help. It is a little slippery if it rains for about 2 weeks.
dh1@reddit
This is what we do. Just take an old mop and slop it onto the trailer wood deck to keep the wood moist and oiled up.
incruente@reddit
Some people filter it and burn it as a fuel; search for "black diesel". It can also be used as a fuel for things like metal foundries.
MrHmuriy@reddit
I am sure that without modifications such fuel will work only in low-tech diesel engines, such as the Lister engine, and even then I am not sure that modern synthetic motor oils are suitable for this. And to use waste motor oil, as well as waste vegetable oil in engines of old cars, such as the Mercedes W123, additional equipment is installed on them.
Dangerous-Kick8941@reddit
Synthetic burns fine in my 5.9 Cummins.
kkinnison@reddit
Nope
just get it recycled. far better for the environment
LtDangley@reddit
You don’t like everyone’s idea of spreading it out in the ground? You must be one of them people that like healthy food and water
kkinnison@reddit
Yep good way to poison your ground water. Had a neighbor do that and we recorded him dumping it on the side of the road and get got fined.
AshamedCareer7007@reddit
Wonder if you can lubricate garage door springs or will it gunk it up
mczplwp@reddit
I used to add used motor oil to my #2 heating fuel. Never hurt a thing. With 2 vehicles it was maybe 10 gallons a year
RealTeaToe@reddit
As well as still being a hydrocarbon that will produce oodles of joules if burned, it can be used as a rudimentary sealer for wood.
No-Comedian3768@reddit
Too much pollution when you burn the used oil. There are other uses that don't put your health at risk.
RealTeaToe@reddit
Totally agree. It would be wiser to just make a wood gassifier, but that does take a modicum of skill.
hysys_whisperer@reddit
Much better as a sealant than being burned.
The additive packages include a lot of rather nasty stuff if burned.
RealTeaToe@reddit
Agreed. I've been wondering if I should start trying to snatch up old ass trailers and fix em up for some side money. Used oil sealer is a good step to doing it cheaply.
LilacBreak@reddit
I use it to start brush fires when its wet out
Mysterious_Touch_454@reddit
Ants and other crawlies dont like oil, since it melts chitin. Use that how you want.
caveatemptor18@reddit
Pour in snake holes and light it.
angry-software-dev@reddit
It's useful, but at what quantity are you willing to store it "just in case".
I find I have 3-4 gallons at a time between I bring it back to the auto parts store for processing.
I personally don't like the idea of dumping it in the ground I'm growing food and pulling water from -- and you're dumping it if your soaking posts in it, using to clean your garden tools, dumping on gravel driveways, etc...
A waste oil burner is fine too, but only if generate enough waste oil to make it useful.
wtfredditacct@reddit
I keep mine in a barrel, next to a torch, above my portcullis. Really helps deter those damn kids selling girl scout cookies... they're a problem and I have no self control when it comes to thin mints

Always keep it piping hot so it's ready when unexpected guests drop by! 😆
Temporary_Muscle_165@reddit
I recommend some chickens. Add a layer of feathers after. Those little girls are gonna get what's coming to them.
Excellent_Condition@reddit
Wait, do you stick the feathers to the invaders with the chickens still attached? Instructions unclear.
It seems like a good deterrent but a waste of chickens.
Temporary_Muscle_165@reddit
Good point. Keep the chickens, and buy some feather pillows. Throw just the feathers at them after the oil, unless you decide on flaming oil instead of boiling. Burnt feathers stink.
Deciduous_Dan@reddit
Just remember it's highly carcinogenic, so while using it for a fence post, isn't it an issue you want to avoid getting it on yourself. Also something like chain oil is a bad idea because you get covered in a mist of it .
alienfister@reddit
Bar oil and light duty things like that
antbtlr82@reddit
If you are going to do this I recommend putting it through a filter first. Metal chunks even tiny ones will tear up the worm gear. Source tree guy who has seen that mistake made a few times.
Many-Crab-7080@reddit
I have seen it settled out then used in diesel generator as a 10 parts Oil 1 part Petrol mix
Cowboy_Buddha@reddit
Some cities collect it to use it to heat their buildings. City I used to live in had a collection dumpster just for this purpose.
MrHmuriy@reddit
Here people use waste engine oil to heat their detached garages or workshops in winter, burning it in specialized burners and boilers (for example, De Dietrich GT-series boilers)
wortcrafter@reddit
Knew a guy, McGovern type, who built his own heating system which used old oil. Unfortunately when he passed his kids replaced it, none of them knew how it worked.
Actual-Money7868@reddit
You can use it as a fuel oil for a oil burner or to run a mechanical diesel engine.
Search waste motor oil WMO
hysys_whisperer@reddit
Rerefiners distill it to get the metals based additive packages out before burning. That stuff will (ironically) cause some pretty nasty deposits in a boiler if you burn it. Also the exhaust is hella toxic.
Actual-Money7868@reddit
You can use a centrifuge to seperate out the water and the heavier stuff in the mix.
In terms of metal additives Idk, if it's aerosolised properly and ideally preheated it'll combust pretty cleanly in terms of smoke.
I'm sure there's home based solutions.
hysys_whisperer@reddit
I'd much prefer to just use it as dustnet
Actual-Money7868@reddit
You spray it on to your property ?????
hysys_whisperer@reddit
There are commercial dust control products made from the same cuts as motor oil.
https://www.hollyfrontierspecialties.com/en-us/productline/dca-dust-control-agents
Note that agricultural spray oils are also the same heavier than diesel oils, used for an organic pest control to provide a barrier between pests and organic foodcrops.
Actual-Money7868@reddit
That is wild, I've seen water sprinklers/sprayers being used
hysys_whisperer@reddit
The benefit to mineral oils is that you only need a once per season application, because those oils don't evaporate that fast.
Actual-Money7868@reddit
What about vegetable oil? Id feel more comfortable spraying that than mineral oil.
Actual-Money7868@reddit
I hear ya
Gingerfry21@reddit
Idk if it’s right or not, but my old school farmer grandpa uses it for chainsaw lube
mrfixdit@reddit
If you have a large space and large tank full of used oil, a waste oil burner is great for heat!
drowninginidiots@reddit
My FIL would dump it in a 55 gallon drum without a lid, then stand wood fence posts in it. When you needed a post, pull one out. No having to go out and buy pt posts. Sometimes they say there for years before getting used.
A rancher friend used to change their oil on the dirt driveway. Let it spread out and soak in. Great dust control.
Since neither of those things are typically acceptable anymore, you can get heaters or boilers that will run primarily on waste oil. Probably not practical for the small quantity you’re probably talking.
Excellent_Condition@reddit
It's not something I'd do in general, but especially if I'm growing food on my property.
I don't want that to wash into my garden, my water supply, or to wash down to the neighbors.
deathsleaze@reddit
It (legally) does NOT make the best fence "paint" I've ever seen, it lasts longer and gives it a beautiful stained wood look. So remember to NEVER use it as paint. (It's great as paint, but you didn't hear that from me.)
SoCalSurvivalist@reddit
You can make an oil lamp and burn the used oil in it. It's really sooty, but it'll still give you some light.
No-Animator-3832@reddit
Used to see it poured a quart at a time into diesel trucks fuel tanks or pour a half quarter or so on alignment before you throw it in the wood stove

For hobby blacksmithing, it's good for quenching tool steel for things like knives and axes.

Good for keeping dust down on driveways. Just ask Russel Bliss....
It's a lubricant for things that you constantly coat. We used it on chains and other things of the like. Waste oil burner isn't a bad buy if you have alot of it coming in.
