We will be happy to furnish you with all letters, names, and phone numbers of these customers upon request.

"...After about 20 hours, the bypass light came on. [The filter element] was full of iron particles... At exactly 5.5 hours the light came on again! I pulled the screen to find it full of metal for a second time... This time I pulled the engine and took it to the shop for breakdown. [The mechanic] estimated that I had 5 to 15 minutes before engine failure! Without your wonderful ADC system how could I know what was to happen? Answer: I wouldn’t have!...I am most grateful to you for providing this system that adds so much peace of mind when flying... THANKS FOR SAVING MY AIRPLANE AND/OR MY LIFE! -H.N.

"...After a few months I noticed that I would get a faint light from the bypass warning light...One day I asked my AME about it, he looked at the screen and determined that it was particulate matter from the camshaft! I have been using an oil analysis for the last several years and no high levels of cast iron ever showed up. Due to the effectiveness of your filter, and the ease with which the contaminants can be observed, I was able to plan remedial action...I’m very glad I purchased your oil filter." - R.J.

"The filter has become one of the few insurance policies I can depend on...With everything running strong through about 130 hours and no hint of a problem, the filter’s bypass light came on at 18 hours into the next oil change. Then 15 hours, then 12, then 8 1/2 and at the end of the next 4 hours the engine went back to the overhauler. Again, up to this time there was no hint of a problem with performance or otherwise. A tear down revealed not only the culprit—a valve guide had worked loose—but that the engine had been protected completely...Without the [ADC] filter we would have been buying another engine about now. The way I see it, my return-on-investment was about 1200%. Thank you. -M.M.

"I am an A&P mechanic for the FAA...I have had an extensive opportunity to observe and use the ADC filter system...I have found this filter system to be far superior in performance [to] any other product on the market today. In one case, the oil bypass light prevented an impending engine failure. Upon immediate landing and disassembly of the filter, EXTENSIVE amounts of metal were found on the micron screen. SURELY FURTHER FLIGHT WOULD HAVE BEEN FATAL...I personally believe that each production aircraft should have an ADC oil filter system installed as original equipment...The ADC filter system is a sound investment for the future of your engine. I highly recommend the ADC Filter System to any aircraft owner. It works! -R.B.

"...Two hours into the flight, still at full throttle, the oil filter bypass light came on, twinkling at first, then on solid...I removed the screen to find nearly a half teaspoon of metal fragments...Engine was no longer airworthy ...This called for a remajor of the [engine] at 214 hours since last...With all my thanks to ADC’s Oil Filter there was no bearing scoring what-so-ever!! I would not have known of the trouble without the oil bypass warning light until the next oil change which could have been too late to save the internal bearings, and the possibility of in-flight engine failure...I thank you for making these oil filters available to the aviation community and highly recommend that all aircraft have one installed." -J.S.

"I can say that the filter system has lived up to all of your claims and has surpassed our expectations. We have noticed lower engine oil temperatures, increased oil capacity and cleaner oil between changes...the cost savings alone have been enough to pay for the kit in the first 200 hours of operation!...The ADC Oil Filter System is by far the best on the market and I would highly recommend it to all R-22 owners, and for that matter to all owners of general aviation aircraft." -D.M.

"I want to thank you for developing the ADC filter and chip detector...the chip detector light came on and in a few minutes so did the bypass light. On the ground, I found that the ADC filter was heavily loaded with metal particles from the piston. The engine was checked and found to have no other damage and little metal in the case...the ADC filter was able to remove the vast majority of the metal and kept the engine clean enough to keep on running...The price of the ADC filter more than paid for itself in protecting the engine, and keeping me from an off-field landing...YOUR FILTER NOT ONLY SAVED MY POWERPLANT, IT ALSO SAVED ME!!" -M.H.
