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. Tim
