Here is what one of our competitors says about their Separator vs the Airwolf Separators
(For the sake of discussion, we are assuming "Other Separators" means Airwolf Air Oil Separators)

The Truth
  1. Keeps oil at the full mark.
 They say we must start out 2 qts low to avoid a  quick blowout. Nonsense. Airwolf lets you fill your oil up to the top of the dipstick if you want to. What's a "quick blowout" mean anyway?
  1. Seperate all the oil from the air & water, None to filter.
 They say we filter out some oil from the reduced oil supply, remix it with air & water to emulsify it into sludge. Not possible for the competition to separate oil from water.  One chamber inside their unit and one 1/4" drain line. Defies the laws of physics. In addition, the statement "none to filter" makes no sense whatsoever. We have no idea what in the world they are talking about. While they like to make vague statements Airwolf backs up the truth with facts. Their small can condenses the steam boiled off the oil and puts it right back into the engine. Airwolf refuses to do this. as moisture is what rusts an engine. We heat up our AirSeps to above 212F. No water is condensed.  Only the oil is captured The water vapor [steam] goes right out the bottom of our heated AirSep V goo [emulsified oil] to form in places like the inside of the rocker covers.
  1. With full oil, engines run cooler cleaner, better
 They say starting out 2 qts low and blowing continuously lower, engines run hotter and not as efficiently Really? Engines with full oil run cooler? No shoot Sherlock. Airwolf Airseps allow you to fill up the oil to the top mark on the dipstick. We wouldn't have it any other way.
  1. Blowby is part of good lubrication but only if a separator can keep the oil level full.
 They say we do not control blowby, do not separate, & do not keep oil level full. We do not know how they make this stuff up. Blowby is caused by leakage around the scraper ring on the bottom of the piston. While some blowby is found in all engines, it is definitely not a part of good lubrication. Excessive blowby is more a sign of worn rings and/or tired cylinders. No one can control blowby. What we do is manage the blowby which is capture the oil the gets by the rings and stick it back into the engine. Our opinion is that you don't replace cylinders until you are not making power. Blowby is a cosmetic issue that Airwolf can easily manage.
  1. Leaves your plane's belly clean
 They say we continue to make the aircraft bottom dirty. Nonsense.  Our AirSeps are 180%  to 500% larger than theirs which allows us to capture far more oil than they ever dreamed of. Great marketing statements but lousy execution by Brand "X"
