I've never really looked at the DFI oil to know. AND... unfortunately... a quick internet search didn't turn up anything on the oil type and rating. (just the normal fluff on "Superior-bla-bla" crap) I do know it says that its not for use in TC-w3 engines.
My personal feeling is that it will be fine... but until I see a label with what the oil is... I don't know.
Since TC-w3 oils are widely available... I would just stick with a synth, or semi-synth TC-w3 of whatever brand you like.
