Note that the chart from the VW manual show the largest temperature range
for 15W-40, and that it goes to a temperature just as high as the 20W-50.  I
never even knew that 15W-40 was available until I noticed this in a VW
manual and started to look for it.  Before I started using Mobil 1 in some
engines, I used it in all my vehicles, usually Shell Rotella T.
