You could also download the compatibility chart from Chestnutproducts homepage - which is a good starting point.

After Pete made the suggestion I did a search and there are lots of articles saying you can use any drying oil, just let it dry for three days to a week before applying the lacquer.
The Chestnut compatibility chart says No to Lacquer on top of Oil but it’s been incorrect before so possibly not a good source of information for this particular technique.
