Saturday I noted that my Gravely tractor was leaking oil pretty badly at the
oil filter (Kohler twin).  I tried tightening it a little and made it worse,
so I decided to go ahead and change the oil and filter even though it only
had 20 hours since the previous change.  The filter is very hard to get to
with a conventional oil filter tool so I had been using oil filter pliers.
To make sure the mounting base wasn't nicked or something, I took off the
exhaust system to get at the filter.  I drained the crankcase and took the
old filter off and very carefully put on the new one.  I then proceeded to
pour 1 and 1/2 quarts of oil in to the engine.  There was no reading on the
dipstick so I poured in another quart- still no reading and I know it
doesn't hold that much.  I looked down and there was the drain plug sitting
where I left it when I took it out.  Oh well, I've never done that on a car
so I guess it could have been worse.  To make a Studebaker connection to
this story- my 1962 Studebaker-Packard Gravely Model L holds five quarts of
oil (single cylinder Gravely-built engine with pressure oiling and an
automotive filter).
