Technical STP for Steering Box Lube?

That has absolutely nothing to do with putting STP in a steering box but since you brought it up you're saying they got fined by who exactly?

A great deal of claims get made everyday without any validation. As we all know most of the "mechanic in a can" products are pretty worthless but, a few of them can be useful at times.

Wow, I didn't know that a 2023 dollar is worth 80.4% less than a dollar in 1978 but 17 years later that 2023 dollar is only worth 50.1% less than a dollar in 1995? That's very interesting!

 

STP to Pay $700,000 for Its Ad Claims

STP is a viscosity modifier.. thats all it does. Its what its desined to do and thats all. Its to put in old engines with excessive bearing wear to maintain a working oil film an improve flagging oil pressure. Which it does quite well.

 

Thanks for the link but, I'm not subscribing to the Washington Post to read it. I did find more info directly from the FTC for a better understanding of the claims made. The reported claims are irrelevant to this thread.

There are appropriate lubricants engineered for steering boxes. STP oil treatment is not one of them.

 

Yep, Lubriplate #105****embly lube - done the same in several vehicles I've had with acceptable results.
Surprisingly, living in a rural agricultural area I'd never heard about the use of corn head grease until I read about it here on the HAMB. Never too old to learn, are we?

 

I do not have a clue if STP would be a good choice for a steering box or not, I also don't have any information into how much the dollar is worth from then to when, I do know that eggs ain't cheap though. As to STP I personally found one area it excelled in, and that is burnouts. Rub some of that***** on just about any tire on any car drop the hammer and it is the coolest smokey burnout.

 

I didn't realize that a steering box required such specific lubrication standards I guess if it's more than 3 turns lock to lock, you need high zinc content (high performance steering boxes only)

 

Once again, the question and thread goes OFF THE RAILS.

 

Well...STP is pretty slick stuff

 

Yea. And people always trying to re-invent the wheel.

 

In 1963, a Santa Clara friend bought a new over the counter 327 shortblock from Courtesy Chevrolet (San Jose)
He was advised by the parts mgr. (Maurice) to add a can of STP to oil for break in.
Friend did this, and during 'break-in' spun a con rod bearing.
Maurice warranted the engine, and the second one was identical! Break-in spun another con rod brg., when he returned the 2nd engine Maurice said he had to have a meeting with his General Mgr.
He provided a third engine(!) but said, "This time omit the STP..."
True story.

 

have only taken a few steering boxes apart but have use cv joint grease to refill with good luck it is thick enough to stay put but can move around a bit when anything moves and it is very slick and obviously quite a good lubricant this opinion is worth every penny you paid for it

 

Zombie thread season is lasting longer...

 

STP (Stone Temple Pilots) Vaseline

 

People just never seem to remember that one of the "slickest" lubes that can be put in a steering box is,
carbon tetrachloride. (C cl 4) The only thing is, it evaporates in just a few weeks so is not really practical.
Common beef lard works very well also but goes rancid after 6 months and smells bad, but it can be had free many places.
The point is, there are MANY brands and types of "lube" that will work despite your personal and political views
and no one will ever know what is best if you do not take time to scientifically test the problem. Beyond that, it is all random talk. The main fact here is, there are certain things that REDUCE STEERING EFFORT and there are many things that just keep the parts from rusting and work mediocre.

 

I’m stupid.
I’ve got a few shop manuals and use whatever it says.
The message board experts say things from axle grease, 90-140 gear oils, 600w, stp, 0/00, JD cornhead and combinations of all those stated.
With great testimonials.

 

Or 20w50 racing oil

 

Curious as I never used it, but does the JD cornhead grease need to be packed in? And if one were to change it, will it drain out?

 

Yep, you need to pack it in. No, it's not gonna drain. You'd have to scoop it out but really, why would you ever have to change it? I used it cuz a lot of guys have recommended it, seems to be a good consistency and it's cheap.

 

^^^^^ Many others available via other suppliers as well. https://www.grainger.com/product/LUBRIMATIC-Grease-Gun-Injector-Needle-41AA40

 

Was just thinking of “why” as well. Can’t answer though.

 

Well, just think about all those millions of people who get stranded on their daily commute because they didn’t know enough to put cornhead grease in their steering boxes.

 

Why on earth would you ever do something crazy like that?

 

That’s what was told and have in my box.

 

There are some on here that would have us believe they have captured & possess all the knowledge in the universe !

 

Man this corn head***** is as popular as that corn hole game lately. Lucky me I've only ever had to rebuild 1 but refilled a couple in my day. Long ago someone gave me some***** he called 600W but it seemed thicker. I had to scoop it in or warm it real good and let it flow. Smooth operation, no grinding or galling, no leaks. But then again Packard boxes are pretty superior to begin with.

 

I bought a 1965 Comet brand new. Had a graphite type grease, never had to add or did it leak. Somewhere around 135k miles.

 

I’d like to use corn head but cleaning out the chassis grease I put in mine after I found it empty a month after I bought my car isn’t go into happen.now if it’s possible to open a drain and force it out … that would be different.

 

They were fined by the Federal Trade Commission, twice and for the same reason.

Re-math your math:

90W-140 and 600W are nearly the same thing. One is an SAE rated oil, and the other is an ISO rated oil.

Two different scales, yet close enough to interchange.

 

Its what i started useing in the my model A but 7 tooth are notorious leakers and the relativley small fill volume meant constantly refilling it. I now use a self leveling steering box semi-fluid grease (silimar to 00 Grade) designed for vintage steering boxes. Now no more leaks.
