POLARIS Laboratories® Helps with Quad Z Requirements

POLARIS Laboratories® is prepared to help its customers meet EPA NESHAP regulations that began on October 19. The Quad Z regulation requires an oil change on spark ignition reciprocating internal combustion engines (SI RICE) unless fluid analysis can prove the lubrication meets EPA thresholds. 

HORIZON®, the company’s award-winning application, is capable of analyzing sample data and sending an alert to customers when the fluid exceeds the Quad Z thresholds. This alert is necessary since the EPA only allows two days of operation after fluid analysis identifies an exceedance. Violations of the rule could result in $25,000 fines.

In addition to Quad Z analysis, customers will receive POLARIS Laboratories®’s exclusive maintenance and reliability recommendations based on the sample’s metals, contaminants and fluid properties. These recommendations help customers prevent equipment failure, increase uptime and save money.
