Miles Lubricants MSF1559005 Compressor Oil 1 gal Bottle SAE 40
One-gallon bottle of SAE 40 compressor oil with ISO 150 viscosity for rotary compressors
- SAE 40 viscosity suits high-temperature rotary compressors
- ISO 150 grade matches OEM fill specifications
- Diester base oil resists oxidation and deposit build-up
- Viscosity index 118 keeps film strength stable across temperatures
- Flash point 502 °F adds safety margin in hot-running units
Product Identity
Miles Lubricants MSF1559005 is a one-gallon bottle of SAE 40 compressor oil formulated for rotary compressors. The fluid uses a diester base stock and carries ISO viscosity grade 150 with a viscosity index of 118. It is supplied new and ready for industrial maintenance use.
Suitability
This oil suits operators of rotary compressors requiring an SAE 40 diester lubricant with a flash point of 502 degrees Fahrenheit. It is not food grade, so facilities needing NSF H1 registration should look elsewhere. Buyers needing a different viscosity grade or a synthetic hydrocarbon base stock should select another product.
Deciding Specification
The SAE 40 viscosity grade combined with ISO 150 and a diester base oil determines compatibility with specific rotary compressor designs. Viscosity measures 150 cSt at 40 degrees Celsius and 16.6 cSt at 100 degrees Celsius. Confirm these values match the equipment manufacturer's recommendation before purchase.

Questions about this item
What viscosity grade does the 1 gal bottle of Miles Stratus D compressor oil carry?
The oil is rated SAE 40 and ISO 150, with a viscosity index of 118 and measured viscosities of 150 cSt at 40 °C and 16.6 cSt at 100 °C.
How do I install this compressor oil and what step is commonly missed?
Shut down and depressurise the rotary compressor, drain the old diester-based fluid completely, then refill with the 1 gal bottle to the sight-glass level; the step often missed is a full drain before adding the new SAE 40 oil.
When will this diester-based compressor oil need replacement in a rotary compressor?
Monitor the fluid condition and change it when analysis shows viscosity drift from the 150 cSt baseline, acid-number rise, or after the compressor manufacturer’s recommended service interval.
