Oil freezing?? Not on this planet. Oil may get extremely thick but won't freeze except for tar oil which is used in making asphalt. This I'm sure is as someone else said is for legal reasons i.e, EPA. Remember if the EPA had its way racing, track days and V8 engines would be out lawed, they don't believe in fun!
