For what it's worth, my BIL is an "A&P" (Airframe & Powerplant) mechanic. He uses Amsoil, changes it every 15k with a filter change every 7500.

I know I must be stupid....but I see this allot....(changing the filter BUT not the oil....) and I can understand why...
BUT I honestly would love to know how to pull that trick off without having oil run down my arm past the elbow and up to my armpit....
Just curious...
