A scroll compressor comprising:
- a non-orbiting scroll member and an orbiting scroll member each having a base and a generally spiral wrap that extends from said base, said spiral wraps inter-fit to define a compression chamber there between, wherein said non-orbiting scroll member and said orbiting scroll member each comprise a microstructure having graphite nodules, and said non-orbiting scroll member and said orbiting scroll member are radially and axially compliant relative to each other;
- and
- an ether-based lubricant that coats at least a portion of said non-orbiting scroll member and said orbiting scroll member, wherein said ether-based lubricant has a viscosity between about 1 cSt@40° C. and about 140 cSt@40° C.
