Aerospace lubricant refers to the use of aircraft and ground airport equipment lubricant that comprises aviation transmission system oil, aviation grease, and aviation engine oil. Choosing the most suitable lubricant for space mechanism includes a choice of most functional and lightweight lubricant. This is because additional costs are incurred for each pound in total weight added during aerospace operations. Furthermore, using heavier lubrication would only cause considerable financial significances on top of possible technical or mechanical concerns
