Wanting to get to know my plane better (and save some money), I decided to change it myself.
The mission had three objectives:
1. Do the job without going to get help from the FBO guys;
2. Do the job without making a mess;
3. Get the job done without any leaks.
That said, I was careful. To prevent spills on the ramp, I went out and got a 4'x4' piece of cardboard and put it under the front wheel to keep any drips off the ramp.
Then I started.
Step 1. Start engine and run it for a couple of minutes to heat oil.While engine turns over, go get wrench for filter from car.
Step 2. When half way to car, realize that plane is leaving because you did not set the parking brake. Chase plane across ramp, stop it, and hope that no one at the FBO or in the tower saw that. Taxi plane back to parking spot, set parking brake, and go get wrench from car.
Step 3. With engine warm and turned off, find drain plug on bottom of engine block.
Step 4. Congratulate self for not spilling single drop of oil, even on cardboard. Cut safety wire from filter and
Step 5. Pour half quart of new oil into new filter, lubricate filter gasket with oil, and
Step 6. Get filter into place, tighten down, and safety-wire it into place. Admit to self that safety-wire job looks like a special-needs kid did it blindfolded, but at least it's tight.
Step #7. Start engine and run for 60 seconds. Check for leaks. Do happy dance when you realize that there are none. Yay! Look over to FBO to see if anyone saw happy dance.
Step 8. Clean up mess, which by now includes oil on tarmac, oil on plane wheel pants, oil in hair, on face, arms and shirt. Change shirt.
Step #9. Update engine log to reflect oil change. Make note to self to get price for next oil change from Airframe and Powerplant shop across field. Whatever they charge for the job, it's gonna be worth it not to have to go through this again.
But it's done, and it's done reasonably well. Objective #3 was accomplished.
