  • This 600 Weight Oil Is Necessary For Many Early Fords
  • It Is Nearly Impossible To Find Locally
  • It Saw Use In Differentials, Transmissions, And Steering Boxes
  • Will Not Attack Brass Or Bronze Parts
  • One Quart

The lubricant used in the early days of motoring up into the thirties was a very heavy clinging type of lubricant known as 600 W Oil. In viscosity it is very much like today’s S. A. E. 250 Gear Oil but is easier on soft metals.  It was used in differentials because full floating rear axles were not in general use, and allowance had to be made in the seals to allow the axle to move up and down as far as a quarter inch. To prevent the oil from leaking at the wheels the lubricant was made to cling to the gears.  The same principle applies to transmissions and steering boxes.  

In today's cars the seals can be made to fit very closely due to better engineering and materials, therefore lighter weight lubricants are used.  The main causes of oil leaking at the rear wheels are worn seals or bearings, but over filling and/or using a lighter weight lubricant than recommended can also cause leaks.  This 600W oil comes in a quart bottle, and it contains no additives that could attack brass or bronze parts. Using this weight lube will help eliminate oil seal leaks.

TIP: Leave rear axle 600W 3/4 inches below filler opening; overfilling is the main cause of rear axle leaks.
