Extraordinary Service Makes A Huge Impact
L. Farr, Non Destructive Testing Group, Metal Producing Industry

“We have been very pleased with the services provided by TestOil. The same day analysis is extremely important to our operations. There have been several incidents when the test results have been critical in analyzing issues with a component and receiving them so quickly was vital to our program. The great service provided by the customer engagement team has been extraordinary as well. For instance, in the last couple of years we have had a multi-million dollar expansion at our location. This brought hundreds of new oil sample components to our program that needed to be added to our database. With help from Ashley and Jessica at TestOil, we were able to add everything quickly.”

TestOil has served this customer since 2008, processing nearly 70,000 samples for 25 different locations. They are a global leader in lightweight metals technology, engineering and manufacturing. The world’s third largest producer of aluminum, the company has corporate headquarters in NYC.

TestOil is a Company That You Want in Your Corner
C. Dean, Sr. Reliability Specialist, Power Industry

“I have been a continuous customer of TestOil since 2002. In that time I have worked for 2 different companies that both used TestOil for testing of the lubricating oils. Both of these companies have benefited tremendously by consistent quality and a very quick turnaround of our test results. TestOil is a company that you want in your corner. With a wide range of tests available to solve your problems. In my opinion their biggest attribute is the unmatched customer service. From the customer service department, to the analysts in the lab, TestOil always comes through for us. I recommend using TestOil for your oil analysis – you will not be disappointed.”

Customer testimonials

"We have used many different oil analysis labs, but they strictly provided a service to us. We never considered our lab a partner, until we started working with TestOil. We have a great relationship with several of their analysts and can call them if we ever have issues or questions. This had made a huge difference in the way we approach and solve problems."
