An old friend, who has worked on 50's cars for years, (he's 78), says to fill my new steering box with STP, because it will stick to the gears providing better lubrication. Thoughts???

I have used STP oil additive in the steering gear boxes in old cars for years, it works great and is very slow to leak out. I always set the can of STP out in the sun for awhile to warm it up and make it more easier to pore. I then put a small funnel into the fill holes and slowly pore the STP into the gear box.. I check the fill level several times to make sure the gear do is not to full. Pep Boys sells a product called Motor honey that is very thick and quite similar to STP. Several of the old car guys recommend a product made by John Deere, Corn Head Lube. I thing it is a very thick lube that reputedly works very well on leaky steering gear boxes. I like the STP,Motor Honey because I can pick it up anywhere. Bill 36 5 win delx cpe

I've been using John Deere cornhead grease for years... no drips and it is designed to stay where it is needed. Mike "Kube" Kubarth

STP is a motor oil additive and may not provide the lubrication needed in the high pressures of the worm and roller gear box. STP makes a gear oil additive, but I don't believe that it is sold in this country. Corn head grease has EP additives and would probably be a better solution to the leaking gear box than STP. The best solution is to rebuild the steering box with new bushings,bearings and seals and then use the proper grease. As an aside, just because you are old and worked on cars does not make you an expert on lubrication. I am in my mid 80s and worked with both mechanicals and electronics for most of my life. Lubrication is a specialty in most companies that make products that move and have friction components. Just because you used something and observed no bad effects doesn't ensure that someone else using that product will not have bad results. A lubrication engineer will test the product under different conditions and examine for wear and deterioration after each test. Tom This message was edited by TomO on 4-3-18 @ 8:04 AM

TomO is right. STP is not a lubricant. It is a Viscosity Index Improver, meant to be added to oils to raise it's viscosity. Like changing from 20 weight to 30 weight oil. You need an oil type lube in the gearbox, and there are several to choose from, most in the 90 weight range, or even higher. BT

Ford specified "EP" lube (extreem pressure) STP does not fill the spec.

I use this lube specifically designed for vintage steering boxes....also helps stop or slow down common leaks. Penrite Steering Lube, Australian product but available here in USA from Restoration Supply. Here is a link: https://www.restorationstuff.com/ecommerce/index.php?main_page=product_info&cPath=111_112&products_id=710&zenid=b632ie6mohp3eanrj56sjpspm2

I agree with using Penrite. I bought my '34 roadster in 1996 and it had (and still has) tubular steel headers on it. The driver side header nearly touches the steering box so there is no room for a heat shield. The box always leaked and made a big mess, especially after long drives until I filled it with Penrite. My bottle came with just a standard lid so it took a long time to fill the box but now I never need to add any fluid or clean up the mess.

Penrite seems to be a better choice than corn head grease when you look at the vague specifications. It is a semi-fluid while corn head grease is a soft grease. Both claim to have similar lubricating, corrosion, EP and temperature properties. Tom
