Thanks for the info George.I have never talked to anyone about this
before.I got the idea one day and just tried it and it seemed to work
fine for me.Even on a 15 degree day,the oil would almost boil if you
left it in over 10 min. or so.I change my oil every 20 hrs. so I figured
that it would be okay.After your post,I think I will reconsider,Jim
