Howdy, Boys:
Based upon a recent thread on this forum, I went into the NAPA store to get some GL-1 90 wt for the ol' Super H. The fellows there said, "Oh, no. You do not want that stuff. It is old fashion mineral based."
I replied, "Well, I have buddies who know old tractors and they say GL-1 is the right stuff."
Said they, "No-no-no. You will be much better off with this here GL-3-4-5 80w-90. It replaces that old GL-1."
I think they are well meaning, but wrong. Please re-verify for me that GL-1 (mineral based or not) is the correct lube for the H. It is the "mineral based" part that threw me....
Thanks.

This is from Pennzoil's website:

[quote:56d533783f]The extreme pressure (EP) additives in most gear oils contain sulfur-phosphorus compounds that

can be corrosive to certain �yellow metal� components, if present at levels higher than

recommended by the equipment manufacturer. �Yellow metals�, such as copper and brass, are

found in transmission synchronizers.[/quote:56d533783f]

GL-1 does not contain extreme pressure additives (At least Pennzoil's doesn't according to their website).

I was wondering, I used the 85W140 oil (IH Brand)GL-5 in my H. Is that ok?

Gear lube came from squarshed dinos?
Poor Barney! Maybe you guys should be using the synthetic GL. Save the Dinos! third party image

Mike,

Was it really more expensive for you to try the GL-1 rather than a GL-3/4/5?
When I went looking around for prices, I only found 1 oil that was a GL-5 (it was the Accell brand, available at Advance Auto Parts, some TSC stores) that was cheaper than Napa's price for the GL-1.
I ended up paying 39 dollars a pail at NAPA for the GL-1. The accell was $33.33 a pail, and the next closest deal I could find was $54 a pail for a GL-5 lube.
Your mileage may vary, but hopefully you can get what you want.
I myself bought the straight 90 weight after the advice from folks here on the forum, and the difference it made to my wallet.

Yes, I didn't lie; it really was more expensive. O'Reilly's had GL-3-4-5 for $33+, and Auto Zone had it for $32+.
The only place that had GL-1 was NAPA at $41.
(All prices for 5-gal quantities.)

GL1 is the "old" gear lube for which the Farmall transmission was designed. GL2 is the same stuff with some anti-corrosion/anti-moisture additives. GL3, 4 and 5 are the same stuff but with EP (extreme pressure) additives. These lubes are intended for worm and spiral bevel gear sets which operate under sliding and extremely high tooth loadings.

It's alleged certain EP additives can be corrosive to "yellow" (brass) transmission parts (bushings, cone synchronizers, etc). Also they may cause increased tooth wear in relatively lightly loaded straight spur and bevel gearsets such as are inside old Farmall transmissions.

However GL3 and higher oils will probably work fine in an old Farmall. (Fresh GL5 will certainly be better than the 50 - 60 year old oil and water mixture usually found in these things!) However given the choice I'd opt for the GL1 (or GL2) lube that these transmissions were originally designed for.

I am not a gear lube expert but I have tore down and rebuilt literally hundreds of worm gear style gear reducers. Every one of them that I have taken apart has had "yellow " components namely the worm gear. The worm itself is usually steel. I doubt that EP additive would be harmful to the very component that it is there to protect.

Just to add, I heard the same story on another color tractor, and bought the universal multi-weight oil and promptly put it in. The next thing I know my clutch is sticking. It took a while for me to connect the two, but finally figured it out. I drained the oil, put GL1 in it and while it took some time the clutch stopped sticking. No doubt my front tranny seal was shot, but held pretty well with the old oil in it until I ruined my clutch with the new oil. Lesson learned, and if those old tractors lived with GL1 and water in them for over 50 years they will likely work fine for another 50 with new GL1.

Well, that's it then. I'm going with the GL-1. Thanks. mike

Not to tell my age but I was taught in grammer school that oil came from the dinosaurs that died. I remember smelling the 90 wt as a kid and thinking "they stunk". I.ve not looked too hard around here but all I've bought is GL-3, 4 or 5. It may be an improvment over GL-1? Is there any chemical engineers on this site? That's not into dino popo? David.

GL-1 will work but I have used the later multi purpose gear lube for at least 40 years and it works fine too.

Mike, we have run GL-1 90 weight in all our old Farmalls, some since new and no problems yet with tranny or differentials. Not saying it is any better than any of the other oil, but it works just fine. If it was good enough in 1947 and many thousands of them are still working, I don't see how it could be to bad.

Me neither, George. And, since it is mineral based, it may be that it is more friendly to the old seals in the transmission and differential than the new stuff. Thanks to you and Allan for the verification that it is okay. It costs more than the new, but I am going with it.

Mike,

When those old tractors were built and the manuals published, many parts of the country didn't even have electrical power, running water or paved roads.

That's why any heavy oil of today's vintage will work just fine.

Heck, ya can even butcher a pig, melt down the lard and she'll run on it. :>)

I am of the opinion..that IF today's lubes were available in the 40's and 50's when these machines were built, the design engineers would have specified their use. But, they weren't.

I agree with the rationale that if the lube worked for 50-60 years, it must be OK. Empirical evidence proves that point. I also tend to believe that what is currently available (the newer stuff) is also just fine.

I don't buy Hy-Tran for my old Farmall SA. It gets ATF and it works perfectly. I don't go looking for that nasty old yellow grease that was popular back in 1953, but use what's on the shelf today. I don't run straight 30W motor oil either..it gets HD 10W-40. The gasoline is unleaded regular as opposed to leaded gas. Guess what? It runs just fine. Nothing has fallen off, seized, or blown up. And if it does....I'll attribute it to 54 years of wear and tear before I will to the modern lubricants.

Yep,

That's what I like about the old stuff. It was built to do a job, not to run a certain amount of time and then wear out so that it has to be replaced.

Ya can't kill this old machinery with a big stick and it just can't be improved upon. :>)
