MIL-PRF-3150E - Medium Preservative Lubricating Oil

We perform lubricants testing by military specification MIL-PRF-3150, which covers a general purpose lubricating oil intended to preserve metals. This grade of preservative lubricating oil identified by Military Symbol PL-M and NATO Code No. O-192. The lubricating oil is intended for the preservation of ferrous and non-ferrous metals and as a general purpose and ordinance lubricant where light loads are anticipated. However, this oil is not intended for the protection of interior surfaces of internal combustion engines.
