We sell only the highest quality compass oil available today. It is designed for Ritchie compasses but is compatible with most oil filled compasses. It is important to note that this compass fluid may not be compatible with some compasses, especially compasses that were originally alcohol-filled. The very early fluid-filled compasses made from around 1860 were filled with an alcohol and water mixture. Compass oil was not commonly used until the 1940's. If there is any question about what type of compass fluid is needed please contact our repair department.
