If you haven't changed `org-latex-compiler' (globally or in the Org buffer using a keyword), it's using pdflatex. >> 3.

This variable is used to identify LaTeX fragments when calling `org-latex-preview'. All subsequent checks involve the org-element api, but for reasons I can't recall at the moment the initial search is via a regexp. Karthik
