Because I'm not "all there" upstairs. I keep the filters after use in their original little boxes and I mark the boxes too. I keep the air filters as well, and I also keep the crush washers from each oil change.Originally Posted by 04.SPT.WRX
The receipts go in a file in the house and get marked with the install date and miles also. The used parts go in the garage up in the rafters where nobody will notice then and discover my secret. I figure if my motor explodes they'll have a more difficult time saying "well you didn't change the oil!"
That's a good idea, thanks!I mark my filters 1 2 3 4 so I can see how many turns to tighten.
