After reading 'DJohnsens' remarks, one is left to ponder who is right and who is wrong in this debate,
Perhaps breathing engine and apu oil fumes is completely harmless and safe.
Perhaps the many reports of pilots suffering from headaches, dizziness, nausea, sore eyes, fatigue etc., after breathing in these fumes, are simply the product of a 'sensitive type' pilot, someone who has a vivid imagination, a troublemaker.
Perhaps when Exxon conducted safety tests of their Mobil Jet Oil on some laboratory hens and found it to be safe, aircrew should be satisfied, with this unbiased report.
Perhaps it's just a coincidence that some of the ingredients of Mobil Jet 2 are to be found in Sarin nerve gas, insecticide's, Gulf war personnel.
All I would say to anyone reading this thread, is to be aware and informed of the very real dangers of 'fume contamination' and don't just ignore it.
