Av8 Posted November 15, 2014 Report Posted November 15, 2014 Install quickdrain - but don't leave a piece of hose connected to it between oil changes - vibration etc. will wear it out and cause leaks. I typically fly the plane, then hangar, drop cowls and start the oil draining - leave it overnight. Come back next day and swap filter, add oil, fly again. I like the soda bottle and other ideas - I just bend the box that the oil filter comes in to create the same thing. I've only changed oil on my J twice - but haven't disconnected hoses etc. like pictures above - less you take apart the fewer opportunities to put it back together wrong... Quote
ryoder Posted November 25, 2014 Report Posted November 25, 2014 My mechanic charged me 55 labor and 4 dollars per quart to change it but I "helped". Quote
RobertGary1 Posted November 25, 2014 Report Posted November 25, 2014 this won't work for everybody but will for those who have a hangar. fly the plane to get the engine hot open quick drain and adapt a hose to let the oil drain go home come back next day most of the oil will have drained and the filter will be cold spin the filter off with one and put a paper towel under the filter with the other one a few drop but no spill I can attest to this one. Also, if you don't let the drain sit open for a good 60 minutes you are missing a good amount of oil. The first 90% comes out right away. The last 10% comes out amazingly slowly. There also is very little reason to change the filter every time. The filter should be good for 50-100 hours. An oil change without the filter (and a quickdrain ) can be done very simply. -Robert Quote

You must have some data from testing the condition of a 50 hour oil filter. I'm very intrigued, please share.... Quote
MB65E Posted November 25, 2014 Report Posted November 25, 2014 The break down of the filter element due to heat cycles doesn't occure till around 50hrs maybe more. The glue and paper where it attaches to the edges of the canister can brake down after that long. Personally, If I only have about 10 hrs on the oil but 3-4 months have gone by, I just dump the oil on a calander cycle and continue to run the filter untill at least 25 hours have past. This way, there is always fresh oil. Side note, I pulled the filter (Fram 8081) on my wife's X3 after 1 year on synthetic oil.... The glue was completly shot and the filter element was just floating around the canaster. Still in somewhat of the same shape, just not attached to the edges. Might do less than a year on the next filter. Best, Matt Quote
jetdriven Posted November 25, 2014 Report Posted November 25, 2014 Fram filters are known to have crappy internals. One filter for the Ford 5.0 mustang has a cardboard "X" instead of a spring behind the element for a bypass relief. when you cold start it, the cardboard crushes and the filter comes off the threaded side of the can, effectively not filtering anything. I ran my Honda Accord 33,000 miles on one synthetic oil change and a Mobil 1 filter. it looked pretty much clean inside the filter and the oil came back form blackstone as "serviceable" EDIT: Here it is. Car has 90K now. uses a quart in 10K miles as it did new. oilreports.pdf Oh, shoot. It has 90K that's another 36K miles. Time to change the oil again 1 Quote

Very few pilots get 50 hours out of their oil. 20 is probably common but 10 is very common too. No need to throw out a filter at a 10 hour oil change. -Robert Quote

Thanks for clarifying Quote

Tires are pretty inexpensive too in aviation terms. You could change all 3 at each annual as well. And some do. -Robert Quote
