	I'm currently using 20-40(20-50?) petroleum base oil in my
	'77 Chevette, 4cyl, 1.6 Liter engine. (Don't ask why.  It's
	a long story.)  I would like to switch over to a synthetic base
	oil, probably 5-50 or something like that.  Is it safe to do
	this gradually as the car needs oil, or should I drain the engine,
	and put the synthetic in all at once?  Also, any recommendations
	on a good synthetic to use?  I frequently make an 80 mi trip (one
	way) on interstate routes at high speeds.  If I were to make a
	gradual change, it would take a very long time, as the car doesn't
	seem to use up the oil thats in it already.  The level hasn't
	changed since I had the head replaced a month or so ago.
