Traveller Universal Tractor/Hydraulic Fluid

[TSO]

And if goes back to the old saying, "Oil is oil. NOT!"
Different additive packages make the difference!
I once owned a truck that used ATF in its 4 speed manual transmission.
Many years ago (early 80's) I used ARCO Graphite motor oil in all my vehicles, but since Atlantic-Richfield pulled their products out of Louisiana, I use Castrol in all my gas burners and Shell Rotella T in the tractor.
People swear that gasoline is different by brands, so is motor oil!
There is a brand of cheap oil sold at the $stores that states on the back label, "Not for use in modern engines built after 1934(?)."
I know a guy that thought "oil is oil" and topped off the engine in his riding mower. Ten minutes later, O
out came the piston rod through the case.
The culprit? 80W90 gear oil!
Oil is different because of the different additives used during its production.

That's rather silly...

Of course 80w90 is different than say 5w30. I'm certainly not advocating that "oil is oil" and I don't think anyone else is either.

Hi TSO,
Oh no, I never thought or stated you said that! Its just that there are so many people out there that will say that. It has been very recently pointed out to me that "antifreeze is antifreeze, NOT!" And it was explained why, and I agree with his reasoning.

When you travel to different parts of the country, isnt the ***air*** different?

Good fortune!

Most people don't realize it, but 80-90w gear oil, and 30w engine oil, are the basically the same viscosity, at room temp. So is hydraulic transmission oil. This fact upsets some people, but if you do your research, you will see it's true.

The viscosity varies slightly, depending on the brand. But, they come in around 30w, on the motor oil scale.

The difference between them, is mostly the additives. Same with a cheap oil vs, a good oil.

The gear oil scale is NOT the same as as motor oil, giving people the impression it's heavier, because it's 80w. It is not. Pour them side by side, you can easily see this.

The 80-90w lawnmower engine story doesn't sound right. It's hard to get an engine to throw a rod in ten minutes, even if you drain all the oil out. Plenty of YouTube video's to illustrate this. If it indeed happened that way, it was ready to throw the rod anyway.

Gear oil is of course entirely wrong for that application, but, it's still lubrication.

I didn't stand there and time it with my watch. I was going on the word of my neighbor, when he asked me to fix it. I asked him what had happened, and that's what he said. I guess it could be said that "I quoted my neighbor." Next time I will use quotation marks and give the proper credits.
Haha!

Good fortune!

Sorry Scott. Not doubting you. Just doubting the story.

Especially, when said, he just topped it off.

 

[w1ebb]

Its all good. In fact, he is not "my friend" but rather a neighbor I put up with. He is a bit of a loud mouth and thinks he knows everything, but can't fix a thing. I had to put a short block on that mower for him.

Good fortune!

TSO has the calm, cool and best - basis comment. I agree 100%.

Are you saying hydraulic transmission oil and atf are more or less the same viscosity or weight? Because my previously mentioned S-10 with 4.3 and 4 speed wouldn't hardly shift gears when I changed fluids in the transmission. I wasn't paying attention to what came out and put straight 30 wt in it. Dadgum thing took a long while to get where it shifted easily again. That transmission required atf to shift smoothly and easily. If the two fluids are approximately the same weight and viscosity, the additives package in the atf made the difference, because it was formulated to be different. Is that right?

They used fiber lined synchronizers on later model manual transmissions which why atf is recommended. Another plus to using atf made them easier to shift in cold weather. The atf is formulated different because of the fibers used in the transmissions.
