Claim 0:
1. A method comprising:
flowing a first lube oil into a crankcase of a reciprocating compressor, wherein flowing the first lube oil to the crankcase comprises:
storing, by a lube oil reservoir, the first lube oil; and
flowing the first lube oil from the lube oil reservoir through a tubing network connected to the crankcase;

flowing a second lube oil to a plurality of cylinders of the reciprocating compressor, wherein flowing the second lube oil to the plurality of cylinders comprises:
storing, by a cylinder lubricator oil reservoir, the second lube oil; and
flowing the second lube oil from the cylinder lubricator oil reservoir to a cylinder lubricator that is connected to the plurality of cylinders;

measuring a liquid level in the cylinder lubricator oil reservoir; and
flowing, based on the measured liquid level, at least a portion of the first lube oil from the tubing network to the cylinder lubricator oil reservoir through an intermediate flowline connecting the tubing network to the cylinder lubricator oil reservoir, wherein flowing at least the portion of the first lube oil from the tubing network to the cylinder lubricator oil reservoir through the intermediate flowline comprises flowing the portion of the first lube oil through at least one of a pressure regulator or a restriction orifice installed on the intermediate flowline, thereby reducing pressure of the portion of the first lube oil flowing from the tubing network through the intermediate flowline to the cylinder lubricator oil reservoir.
