I was supposed to do an oil change on a 1997 or 1998 Civic today and when I removed the drain plug there was no oil to drain! Not even a drop. The oil light was not on when I pulled it into the shop and the engine sounded as it should. Installed a new washer and snugged up the drain plug. I removed the oil filter which felt heavy (full) and hardly any oil came out of that either. The little that did come out did not look like oil but more like tar. Put the 3L or so that it calls for and sent it on it's way. I could not believe what I had just witnessed.
