If you ever need to refill or top off the fluid in your Ritchie compass, the manufacturer recommends Isopar L, an odorless, colorless, refined synthetic fluid. Its low viscosity promotes quick swinging. Won't freeze or boil off at temperatures from -40º to 200º F., and it may be mixed with the mineral oil already in compasses made before 2001.
- Sold by the pint or the quart

If you wish to refill the compass using Odorless Mineral Spirits you will need to make sure you purchase 100% Paraffin based Odorless Mineral Spirits. Other types of Mineral Spirits will damage the compass…"
