Post their are things in the oil.....

Yep... some bad and some good... but, this ain't no truck... and its has parts and pieces that are really not likeing each other to begin with...

These are the facts of oil... your not the first to try and keep it clean and save it... for reuse...

the problem is that the other stuff in oil that wears out... like the aditives... which protect your engine... go away... after time.. that is why they want the oil changed on a time or use interval... no filter will bring them back... nor will the filter take the other stuff out...

Aircraft engines are kinda funny ducks.. they work at a higher temp... and yess the water does go away... by boiling off.. but, the sulfer oxides and silicon products stay... your truck uses a parifin based oil... we use ashless... so it won't gum up the insides... as you can't afford to have that happen... so our oil is more detergent orenented... and while it is working it tries to keep the particles from damaging the other parts by electrochemical contact ... for a better use of words... but, the heat does something else... it keeps on building up acids... and that the filter would not be able to take out...

So just because the oil looks clean... it has bad things in it that will hurt mag, alu and steel parts.. that we don't want hurt... the best way to long engine life... change the oil... get new wetting agents, soaps and detergents into it... and get the old acids out.... besides... by the time you finish buying this system... we can buy lots of oil..... as them filter do wear out... and need replacement too...

Nope been their done that... best filter system on a plane is one that goes to 10 microns and stays their... can you imagine the 50 wt oil at 40 deg trying to go thru this bypass filter.. ???... at 100 lbs of oil pressure.. it will make it into something that the manufacture didn't have in mind.... crushing just about anything...

Then their is the libility thing... check and see if they will back you on your application... bet they won't... smile.. matter of fact they probably will tell you to go get lost... as they want nothing to do with the avation industry or owners... and warn you not to use their product on a aircraft engine... yep... been their too....

Actually the screen is about all that you can use... with spin on filters coming along a little later... but, hey here is one.... for you... why not get all the metal particles trapped in the filter... by using magnets.... some actually think the metal particles are the bad guys in oil... and not the dirt... after all your up at altitude and their isn't much dirt... up their... so its got to be the metal particles that are wearing out the parts... smile... big magnets on the oil filter are the answer... or course the compass will always point north at the oil can... smile....

Its a good idea.. just not practicle and clean oil is in the form of new... for aircraft... if it were clean all the time... we wouldn't know what was breaking when we did the oil analysis... etc... but, thanks for the though tho... and the next time you do your annual... take both engine cowlings off the front... and watch the wheel come up under the pan... ya its real close... I have seen the safety wire when done wrong... cut the side of the tire... renerdering it damaged byond use...

So the others... watch the safety wire up their on the pan nut... make sure it goes on the side with the little bend back... not on the bottom... nothing should be lowere than the flat on the pan nut... just a rule... smile... GMAs
