Use only distillate fuels (ASTM No. 1 or No. 2 Fuel Oil or No. 1D or No. 2D Diesel Fuel Oil) with a minimum cetane number of 35. Heavier oil is generally preferable because of its higher energy content. Contact your AVSpare dealer regarding fuels marketed in your area.
Use Multipurpose-type Grease (MPGM) which contains 3-5% molybdenum disulfide conforming to MIL-M-7866, and a suitable corrosion inhibitor. NLGI No. 2 Grade is suitable for most temperatures. Use NLGI No. 1 or No. 0 Grade for extremely low temperatures.
Engine Oils (EO)
CD - Use oils that meet Engine Service Classification CD or MIL-L-2104C.
CC - Use oils that meet Engine Service Classification CC, MIL-L-2104B or MIL-L-46152.
Hydraulic Oil (HYDO)
Use EO or industrial-type hydraulic oils which are certified by the supplier as having anti-wear, anti-foam, anti-rust and anti-oxidation additive properties.
Gear Lubricant Classification GL-5 (MPL) is multipurpose-type gear lubricant and meets the requirements of MIL-L-2105B.
