Fluid Analysis Testing

Fluid analysis is one of the most useful and important, proactive maintenance support programs available. As you perform scheduled maintenance, fluid analysis allows you to see what’s happening inside your engines and machines and predict potential problems before they become major failures.

Foley Fluids Lab is located in Bensalem, PA. We utilize the industry’s latest technology to analyze over 150,000 oil, fuel and coolant samples each year, with most results available the next day if received in our lab by 11 a.m.
