Have an older IH stalk chopper, model 60, 1000 RPM pto. The gearbox has a very slow leak and was wondering if a small amount of STP would work ok in it. The older 80w-90 would be ok to use but not as easy to find in some areas and some of it seems thinner than it used to be. 140w is even harder to find lol.

Alan I had an older fellow tell me they used to use straight STP in final drives on bulldozers. They would be out on a job and tear up a seal in the final drive. If they had STP in there they could finish the job before they had to head for the shop. He said he used to buy it in 5 gallon buckets. wouldn't know why it wouldn't work in a small gearbox.

I have a John Deere rotary cutter and when the seal got to leaking I used STP, I did notice that it would foam,don't know if that hurt it any, finally I had new seal installed.
When the old seal was leaking I shot the gearbox full of grease and it would last aboot 10 hours of use.

I've heard people say that they could tell when it was used in an engine because there was sludge sticking to everything when they tore the engine down.
But with an engine contaminants are being sucked in and added to the oils when ever it is run. A gear box is a sealed unit and does not take in or create contaminants from burnt fuel.
I think you'll be fine using it in a gear box.

James uses cornhead grease in a few pieces of our equipment that have leaks around the seals. I don"t know the weight (80, 90, or 140, ect) but it has helped. So far we have not needed to replace the seals.

corn head grease or cotton spindle grease
both are 00 grease and will work just fine
good luck

Lubriplate (the white grease) in a squeeze tube #105 at most auto parts stores for about 3 bucks. It's primary purpose is an engine rebuilding pre lube but works great for leaking seals on gearboxes. I use it on my older mowers and on my '63 Ford steering box. Between 140 and #2 grease viscosity.
If your gearbox doesn't have a self venting plug go to the auto parts store and get one. It allows the pressure in the box to remain at ambient and helps to prevent leaks.

Does anyone even know what STP really is ? It might be made by bees.

In a plant I used to work at they would add it in jacquard drive gearboxes that were overheating and leaking. They did run cooler and leaked a little less. That was years ago.

Curious as to where you might be located that you can't find 80-90W or 140W? As stated below, any auto parts store should have both in stock. Tractor Supply has both in stock. Any farm supply store that sells oil will have both in stock.
As to the STP, it certainly won't hurt anything and may help slow the leakage a bit. I expect that corn head grease would be a better solution.
STP works great as a case resizing lube for reloaders. Check out a tube of RCBS resizing lube and compare it to STP and they look and feel identical. It costs about one tenth in the STP bottle that RCBS gets for the stuff in that little tube.

STP ( Specially Treated Petroleum) has been proven to be a hoax. Nothing more than a viscosity index improver.

Something that says on the label that is reduces leaks. Some additives swell and soften the seals to limp an old tired machine a little farther.
Somebody should have a link to a MSDS list soon.

Corn head grease came out partly because the stalk roll seals in Deere corn head gear boxes were letting 90wt get by and they needed something thicker in them to stop the leakage. The gear boxes are high speed and you know what happened when all of the 90wt leaked out. Your gear box is moderately high speed and a seal leaks a little. Corn head grease is the perfect fit for you.
Getting off the subject a bit, I always wondered why IH corn head gear boxes could hold 90wt OK but Deere's could not. The gear boxes are darned near identical, in fact there was a patent infringement brought on by Deere over it. We used to run a Deere 843 head and a IH 1083 corn head side by side on identical combines. 80-90 went in the IH gear boxes and corn head grease went in the Deere. Both heads were speeded up to the max and run 6 MPH. Both brands needed to have the gear boxes topped off with about the same amount of lube in about the same amount of hours.

Lucas will work a lot better and it helps the oil really stick to the gears if you open up a gear box or transmission that's had it in it you can rotate the gears and see how the oil sticks . Corn head grease works well to

I bought a 2 gallon jug of 85w140 for my mower gear box from a farm and home store last year. Was a good price too.

Just inject a large amount of "Corn Head Grease" and forget it...
STP is the best thing (in the Winter) on a Semi 5th-wheel..slicker then anything you will find..

Sure..that was an old trick used in leaking transmissions years ago...just add a little Brake Fluid....won't last long but long enough to SELL it...

I did in my '69 K20 Chevy because had a broken tooth or two. STP is 200 wt, and it worked great. The only problem with it was on cold winter days until it warmed up and thinned out, it was very hard and slow to shift. If you are running a trans cooler though, I wouldn't do it.

I don't believe that about sludge in an engine. The local Ferguson dealer and mechanick was also a pilot and owned his own plane. You know the rulls require more maintainance than normal usuage. He said that with STP he would get 200 more RPM's out of the engine and on that plane that made it like a different unit instead of being overloaded all the time as compaired to without. You deffinatly don't want sludge or anything else in an engine to cause problems when you are a thousand feet in the air.

Extra lube on the gears just makes for more heating and pumping losses to push the lube out of the way. The actual oil wedge the gears ride on is only a few microns thick.
We monitored the bearing temps on the class II DC to AC MG sets. When greasing the open bottom of the bearing housing allowed excess grease to work it way out . The bearings would run warmer for several hours after greasing until the excess lube was pushed out from between the balls and races.Into the catch cup below.
