I got a little paranoid so I changed the oil to 10w30.  I put the thicker
weighted oil in two days ago yet didn't drive the van until today.  I take
the van to the Mall and back (total of 40 miles) and the oil temp gauge shot
up to 220 degrees.  I had never seen it that high before on the interstate.
So when I got home I changed it to 10w30.  Went back out on the highway yet
the gauge read 200 (in was nighttime and the temperature had fallen a
little).  I attributed the temperature difference not to the viscosity
change, rather the ambient temperature change.  Essentially I wasted 4 good
quarts of free Castro oil.  Live and learn I guess.  I still kept the TDi
oil filter though.
