The propane industry is committed to maintaining the highest quality fuel possible. This PERC program offers as-needed testing of fuel samples to help marketers ensure this consistent fuel quality.

A fuel sampling program run by Southwest Research Institute (SwRI) is accepting fuel samples from marketers for testing. This thorough expert analysis can help marketers rule out fuel quality as a factor in equipment performance issues. In the rare case that fuel variations play a role, SwRI will provide marketers with a detailed report and use the information gained to further strengthen the propane industry’s ability to ensure the highest level of fuel quality.
