Mobil Delvac in a 5KCSTQ?

[Alex Kowalski]

Hi folks,

I'm wondering something as the winter approaches.  Normally I use Mobil 1 in
my 5KCSTQ but because we recently got our turbodiesel truck with its
replacement engine running, I wondered if anyone had ever used Mobil Delvac
Super 1300 in their Audis?  It's truck oil, but it's a bit less expensive
than Mobil 1 and we can buy it in bulk.  It seems to me that any oil good
enough for a high-capacity turbocharged diesel engine in a truck *might* be
a good choice for use in my Audi.  And it could cost me a few dollars less
per change.

Any thoughts?
