Product Description

Mobil 600W Super Cylinder Oil is a premium quality, heavy-bodied lubricant made from thermally stable base stocks. It is designed to reduce the build-up of harmful deposits caused by the high operating temperatures of steam cylinders. This chemically stable oil protects against rust and corrosion, provides good film strength, excellent lubricity, and resistance to oxidation and foam.

Mobil 600W Super Cylinder Oil is compounded to maintain adequate lubricating and sealing films in steam cylinders and resist water washing. Compounding also enhances its load-carrying abilities.


Mobil 600W Super Cylinder Oil is recommended for the following applications:

  • Splash-lubricated enclosed worm gear sets operating at moderate to high speeds and temperatures.
  • Steam cylinders, couplings, bearings, and the break-in of compressor cylinders.
