Lucas Hub Oil

[2speed]

I see that Lucas makes a specific oil/additive for truck hubs. There's very little information on it's exact formulation that I can find, but it seems like it has seal swellers in it, and it's also thick. Really thick.


Has anyone used/know anything about it? Is this what Model A vendors are selling as the 600W?

I've used it and am happy with the results. It is heavy viscosity and does not leak out easily.

There is a little bit of information online about this stuff:

https://www.lucasoil.com/product/hub-oil/

and

If the PDS is accurate, this oil is quite thick (85 cSt at 100*C).

Try using John Deere Corn Head grease in place of 600W oil. This grease has thixotropic properties meaning its viscosity changes (lowers) when stirred causing it to flow or circulate. When it comes to rest it returns to its initial viscosity. I use it in my steering box, transmission mixed with 85-140w gear oil, and differential. It eliminates leaks. Go on YouTube and search JD Corn Head grease for more info. You can buy it at JD dealers and Amazon.

There's no information on the additive package in it. Is it like a GL-5 and hard on brass, etc.


When doing long trips I'm trying to simplify my oils, and possibly not having to carry oil with me. Having readily available sources at local auto/truck stores would help that.


Currently 85W-140 seems to be the thickest most commonly available(walmart, autozone, etc).


Does 85W-140 leak significantly out of the transmission?

About corn head grease:
"However, if two greases are mixed, and one has a polyurea-based thickener and the other uses an ISO 220 synthetic base oil, this should not be your main point of risk evaluation. Instead, focus on the cross-compatibility between the two thickeners, the two base oils or the additives in question.
In regard to the compatibility with other lubricants and machine materials, there are several important factors you should consider when selecting a grease. The thickeners should be your first concern, as most are not compatible. This is especially true with polyurea-based thickeners, which are not compatible with most other thickeners. Even two types of polyurea-based thickeners used in two different greases may be incompatible. Therefore, when switching from one grease to another, you should always verify that the two greases are compatible by checking with the manufacturers and/or having a laboratory perform grease analysis compatibility testing."
