Not really. Veggie oil is used to make biodiesel. They are chemically different.

Biodiesel won't cause blue smoke. Blue smoke it oil being burned. So you have oil getting in the the cylinders and burning. I second the valve stem seals, but I can speak about the turbo seal.

I have the same problem and figured it was the valve stem seals, so I will be watching this one to see if it could my turbo seals.
