    I use the 600 but I am wondering how often it should be changed in the gear box and rear. Or is it good for life.

    600w is a type of oil still sold by Mobil. It is also called steam cylinder oil. It is NOT a "weight of oil".

    "The Mobil Cylinder Oil brand of lubricants represents the earliest lubricant product marketed by our Corporation's predecessor companies. 600W Cylinder Oil was produced by the Vacuum Oil Company in the second half of the 19th century and was a breakthrough product of its time. Continual upgrading and application of the latest base oil and additive technology has maintained this product series as a leader in its application areas. While steam cylinder applications are now less common, the reputation of Mobil Cylinder Oils in worm gear applications remains unmatched among mineral-based products."

    From what I looked at, depending on the chart, 600W is anywhere from about 180 to 240 weight.

    Just from what I've tried, 140 or 250 works just fine and its hard to tell any difference.

    When a kid we had gear oil by 55 gallon drums, 140 and 90 weight. In the old vehicles we used the 140. Never had problems or complaints that I remember. But, then we also kept a grease gun filled with 140 weight for enclosed old u-joints and steering boxes. [ thats actually what the grease fitting on the steering box is for]

    Use the attached chart for viscosities. We've used SAE 250 mineral oils from Lubriplate, SPO 288 or SPO 299, which is supposedly similar to the the 1930's 600 wt. and appears much more viscous than 140 wt. Check out the website for all the products.

    I use the stuff from Brattons and never had an issue. That matters more to me then a few bucks difference here or there.

    I use 250 weight gear oil. I read some time ago that 600W was close to 250 weight oil. It makes shifting easier than the thin oil that some sell.

    I am not really sure, but I bought 5 galons of Meropa 680 12 years ago. Near a lifetime supply for $54. I could not justify the price of what the vendors sell a quart at a time. Seems to work well in the customers cars I have used it in. Alittle stiff in the cold until warmed up but few in this area drive in the winter anyway. Rod

    The disappointing oil results.
    by Dennis
    I got the jug Mobilgear oil delivered to me a couple days ago and decided to clear the bench so I can move on. I would recommend not wasting your money on Mobilgear 600XP 460. It is actually SAE 140. I didn’t notice that before I ordered it. I also had a bottle of Mac’s 600W I bought in the past out of convenience from CW Moss. I had identical measuring cups from the laundry soap bottles that...

    I found a gallon of this in my garage which I must have purchased years ago. Does it equate to 600W oil?

    600W Oil Information
    by Kevin in NJ
    The original oil was called 600W. That is not 600 weight. It is a heavy pressure steam oil designed for straight cut gears which is what is in the A. Of course the oils were changed over time and the curent oil if you wish to buy bulk is call 680W depending on brand. You can also contact the guy selling steam oil and get smaller quantities http://steamenginelube.com

    Bratton's differential, transmission, steering gear oil analysis
    by gdaquilina
    Attached are the analysis for the Bratton's gear oil. Blackstone was not able to answer all of my questions as this speciality oil has additives that are not normally found in other lubricating oils that they test. In a phone conversation with the chemist he said that the oil was doing an exceptional job protecting the differential components and could have gone many more miles than the 15,000 it...

    Changing the tranny oil
    by Jamey E
    Does anybody do or suggest doing the kerosene flush when changing the oil in the transmission? We believe the car currently has the incorrect oil in it, & we are planning to use the 600W

    Recommendations on using 600W Oil - unknown age
    by getgood
    When I bought my '30 Coupe Model a back in January '20 it came with various extras. One of those was a box of (5) 600W bottles of oil (see pictures 1 was opened, the other four appear to be unopened).

    I've been slowly going through the car and inspecting and verifying various systems

    I've finally got the time to get to inspecting the the differential and clutch in about another...

    Transmission and differential oil confusion.
    by Blown Gasket
    I never expected this to happen but trying to change differential and transmission oil has me totally confused. I had planned on changing them today but the 2 gallon jug of oil I have is 90W and I had it for my backhoe. In my mind I kept thinking it was 600W. I know I can buy 600w online at many places plus the Lubriplate oils but what the heck are they. I did a search for 250W oil and at NAAPA came...
