Diesel Fuel

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.

Lubricating Grease

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.

Lubricating Oils

Gear Lubricant Classification GL-5 (MPL) is multipurpose-type gear lubricant and meets the requirements of MIL-L-2105B.

General Service Recommendations

Fill fuel tank at the end of each day of operation to drive out moisture laden air and prevent condensation.

Check fuel level with dipstick in filler opening.

Metal breathers should be washed in clean solvent and lightly oiled before reinstalling.

Use clean water that is low in scale forming minerals, not softened water.

Add AVSpare Coolant System Inhibitor to coolant. Follow recommendation given on container.

Wipe all fittings, caps and plugs before servicing.
