Petroleum lubricants alone cannot meet all of the low and high-temperature performance requirements of military aircraft. A new diester type synthetic grease is promising as a low-temperature aircraft lubricant. A silicone grease has been found to give unusual performance in high-temperature bearing tests. New synthetic oils have been developed for aircraft instruments. In testing synthetic lubricants, it will be necessary to modify the standard test methods used for petroleum products and in many instances to supplement them with additional tests suitable to the particular synthetic. In the future, military aircraft lubricants will Be required to meet an even wider temperature range of operability. Synthetic lubricants offer promise in achieving the desired wide range. One of the more immediate developments in the use of synthetic oils may be their use as blending agents for petroleum oils.
