WebApr 18, 2024 · Multi-viscosity oils extend the operating temperature range while still maintaining proper viscosity. However, they have relatively poor thermal and shear stability resulting in shorter useful life. A good alternative is synthetic oils, since they have good temperature viscosity characteristics. Synthetic oils are covered in Chapter 2. WebSep 28, 2009 · If when you remove the piston (damper) from the dash pot, you know, unscrew from the top and pull it up you can feel the suction for the first quarter inch or so all is well.
