Pure Oil Technologies, formerly Eye of the Tiger, LLC, is a family-owned business with 59 years of combined experience in providing superior service and customer satisfaction.

During our extensive time in the field, we have learned that by adopting a comprehensive equipment maintenance program, companies save boatloads of money in repair costs and also reduce downtime from equipment being offline.

Contamination of oil is the number one killer of mining and construction equipment. With a regular oil change, you only get 60% of the oil, only 60% of the contamination.

Pure Oil Technologies specializes in oil cleaning and drying services. We offer on-site oil analysis, system cleaning and oil filtration and we can do it in the time it takes to complete a regular oil change.
