Guest bobgould Posted November 27, 2013 Share Posted November 27, 2013 I am woking on a 1928 Chevy truck the manual calls for 600 weight in rear end and transmission, I was wondering if 85/140 weight could be used instead. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted November 27, 2013 Share Posted November 27, 2013 You can still get the 600 oil. Old Ford suppliers and vintage oil companies have it.Modern oil is not a good substitute. Link to comment Share on other sites More sharing options...
Larry Schramm Posted November 28, 2013 Share Posted November 28, 2013 Some of the modern oils can attack the bronze in different assemblies. There is a thread that talks at length of the reasons not to use modern oil. You can buy GL-1 600 wt gear oil but it usually comes in a minimum of a 5 gallon container. I know, been there own one.

TexasJohn55 Posted November 28, 2013 Share Posted November 28, 2013 Larry, don't any of our modern (50's on up) differentials have brass or bronze in them? John Link to comment Share on other sites More sharing options...

Larry Schramm Posted November 29, 2013 Share Posted November 29, 2013 Here is what I use. It is from a company called Lubriplate. I use the 600wt oil in my transmission gear box.http://www.lubriplate.com/Online-Store/Late-Model-Rear-End-and-Differential.aspxThere might be some brass/bronze in some later axles, but I am not aware of any brass or bronze. I just know that I have been told by many persons including lube companies that old cars should use a GL-1 axle lube of the same wt as recommended by the manufacturer. The GL-1 does not have any additives that can attack the brass or bronze.Just what I have been told my many and it makes sense to me. Link to comment Share on other sites More sharing options...

Buffalowed Bill Posted November 30, 2013 Share Posted November 30, 2013 John, I can't speak authoritatively regarding differentials, although some of the worm gears on the cars used a brass worm which would if subjected for period of time would be affected, but the overdrives used on cars of the 30's, 40's, 50's and 60's do use brass and should be of special concern.
