Advance Testing Lab, oil testing Lab for the last 42 years. Our business is located in MAYA PURI INDL AREA PHASE 1 , NEW DELHI-110064, right next to Cleveland. This allows us to be in close proximity to the large companies that have testing Lab there. Some of these large companies test their oil onsite there when they have a problem or a problem with their existing oil. It's just good for them to know that you are available if they have a problem.
