The Purify Fuel Inc (PFI) Team deeply mourns the loss of our Chairman, John Campbell.

John was instrumental in the creation of PFI and its success today. In addition to guiding the growth of our company, he led the Science Committee which helped build the integrity of our product and its applications.  His deep understanding of the issues came from his 47-year career at Caterpillar, Inc where he gained his knowledge of the properties of engines and where he was known for his integrity and honesty.

The PFI Team extends our condolences to John's family and many friends who will miss his wisdom and grace.
