This document summarizes the results of a test of the VITO oil filter system and Oiltester at Rosati's Pizza Pub. The test was conducted over 11 days in July and August 2015 across Rosati's 3 fryers. Key results included increasing the lifetime of the oil to over 11 days in one fryer and 4 days in the heaviest used fryer, saving over 50% on oil costs. Using the systems also improved food quality and taste, reduced cleaning time, and identified a faulty thermostat. The return on investment for Rosati's to adopt these systems was calculated to be 4.5 months.
