[Vwdiesel] Non-diesel oil in diesel engine

[jon]

I just changed the oil on my diesel vanagon, and did a bonehead thing: I
put non-diesel rated oil in. I looked at the Shell jug, and it was not
C-whatever rated. I change my oil so much, I tend to buy cheap oil. But, I
do (usually) make sure it's Diesel rated.

So, any thoughts on what I should do? Drain some, and add a quart of
Amsoil SAE30 diesel? :-)

Thanks,
Jon
