Spray gun to spray motor oil

I use a pipe rigging that was used at a shop I worke3d at for spraying down old machineary with cleaning fluids many yrs ago . The way it's made is take 1/4" pipe , use a Tee , a couple 8" nipples connected to the Tee so you have a straight thru effect . Then use a about 3' of hose with a 1/4" nipple pushed into the hose connected to the 3rd threaded hole of that Tee . Last is an air connection to fit your air line screwed onto the one 8" nipple . Drop the end of the hose into a bucket of old oil & spray away . You will need to attach some weight to the end of the hose in order to keep the end in the oil for suction . Works for me !! HTH ! God bless, Ken
 
If you have compressed air try this: I had a cheap
sand blaster attachment which we put a piece of tube
on the suction side and held a small container of
oil up to it and operated the trigger. Worked a
treat for oiling all our baler and forage harvesters
etc. Needed to paint an awkward and heavy water
pressure cylinder one day and tried it with a tin of
paint instead of oil. Did an astounding job and
FAST!
 
get a airless power painter ,, like the wagner , or similar ,,worx great for me ,,I thin the oil with diesel fuel if its cool or frozen ,,
 
I used a garden sprayer it was patheticly underpowered

I keep my wagner 1/2hp airless full of diesel when not in use

but picked up the smaller Wagner Paint Crew to accomplish said task. The features sounded great: 3/8 HP
at a yard sale

filll it with bar oil from tractor supply or walmart

really really works well
 
I have spray gun that looks like a small pressure washer. It has two hoses going to it from compressor and one from a 5 gallon container of oil. The container that holds oil has an air line to it with 10lbs. pressure to help push oil to the gun.
 
Never tried spraying oil with a paint gun. Paint guns you have to hold vertically so that would be a problem holding it horizontally.

It may be possible to use a spray gun and attach a plastic hose to the metal rod that goes in the paint cup.

If you are using a think oil, it may work. If not dilute it with mineral spirits. The paints I use are oil based and I cut it with mineral spirits.

Should work if oil is clean.
 
I use new 20 weight non-detergent oil with STP. If it gets to heavy I put a space heater near enough to warm the oil. NEVER use diesel to cut oil who wants that damn diesel smell every time you get in your truck.
 
I heard of a on old timer that sprayed used motor oil on the underside of his cars/trucks everytime he changed the oil. His cars/trucks lasted for 20 years.

Just do not let the tree huggers see oil dripping off your truck or they will call the EPA.
 
I just let the leaky valve covers cover the bottem side of the truck with oil. I fyou go fast enough the rear bumper gets coated too.
 
Why do you want oil under your truck? I have old vehicles and I'm always fighting to get the oil cleaned off the underside. For me there is nothing worse than getting covered in oil trying to repair and maintenance a vehicle.

As a painter I do know something about spraying. Either an airless sprayer would do it or a conventional sprayer connected to a pressure pot.
 
There is such a thing as a siphon tip for a blow gun. Tip screws onto the end of an air blow gun and has a hose to stick in a can of oil. I have one I used to use for the manure spreader.
 
I use a 3M body Schutz gun but they don't give them away .
You can find a look alike for far less money .
 
Easy as pie. Go to Harbor freight and buy the hand held sand blaster gun. It has a plastic bottle that screws on to it. Holds about one quart. Works great and just don't spray the rubber lines or disk brakes.
 
I went on Ebay... There I got a "Shutz Gun" undercoating gun with 2 spin on bottles.. I can take out my tail lights in the bed and reach the front of the bed with no problem.. I lay down a couple of sheets of rolled plastic back the truck over it and spray my hearts content with half tranny fluid and boiled linseed oil.. Runs out for weeks on end.. then roll up the plastic and dispose of it.. Done....

Don't live in the rust belt, eh?
 
No, I live in north Texas. If rust was an issue though I believe I would use an automotive undercoating rather than oil. Oil will mix with dirt and eventually hold water under it.
 
That's an expensive option that has it's own pitfalls. If you start with a brand new vehicle that's never seen salt it works pretty good. Otherwise you're sealing the salt in. Trust me, those of us in the rust belt have several million lifetimes of experience fighting rust. Oiling the underside and inside of doors, frames, etc works pretty good for the cost of used oil and a little labor.

Now, if I wanted to know about A/C in a car, someone from Texas would be the kind of guy I'd listen to!

Growing up in Corpus Christi some of us in the well servicing sprayed burnt oil (used crankcase oil) & diesel on the underside of our rigs and pickups annually after a thourough cleaning. Then we'd immediately drive them over dirt roads and right-of-ways so the dust would cake in the oil. Sometime a 2nd layer was added. Once undercoating came along we pretty well stopped doing it on the pickups but the rigs continued to get it. And if you ever were the one to get to climb under the rig and clean the old homegrown undercoat off you'd discover what a fantastic job it did. On the gulf coast it was not unusual for those driving an older vehicle in those days to watch the stripes of the road roll on by where a floorboard once set.

[b:ccf5cbcea2]jeffcat[/b:ccf5cbcea2] - I took your advice and got this exact gun. Looks like it will work great. What do you recommend using to clean out the spray nozzle tip after spraying the oil? Thanks for a great tip!
 
Okay, I just used this sprayer today. Don't think I need to do anything with it in particular after finishing. Just poured the remaining oil back into the jug, wiped the sprayer down and hung it on a peg in the garage.



In case anyone wanted to see what this looks like. I paid just under $25 at Harbor Freight. Added a $2 quick-release adaptor and was good to go. This is exceptionally fast and easy to use. HIGHLY recommended!
