replacement oil

[Guest bobgould]

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.

You can still get the 600 oil. Old Ford suppliers and vintage oil companies have it.

Modern oil is not a good substitute.

[Larry Schramm]

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.

Larry, don't any of our modern (50's on up) differentials have brass or bronze in them? John

Hi,,,Pretty sure Don Lang,,,model T parts ,,Ashburnham Ma

carries 600 in qt cans,,,Google "model t parts" should

come right up,,,Hes a full time,,full service model T supplier

That his business,,

AS backup,,,If you have any Stanley Steamers in the neighborhood

they usually use it in the cylender lubricator,,

There is also grade 1000,,,and 1500,,hi superheat oils,,not compounded,,

Perhaps someone can elaborate here,,,,

Here is what I use. It is from a company called Lubriplate. I use the 600wt oil in my transmission gear box.

There 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.

There is a place in west Boylston,MA (modelaparts.com) called Tam's that also carries 600 oil $7 per quart and $26 a gal.

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.

Bob,

One place you should know about if you have a '28 Chevy is "The Filling Station." It is the best source for new chevy/GMC parts and they have 600 wt.
