No Yes, quest is enchanter specific. Don't give up so soon! Considering an EQ developer created the item and most likely used a gas powered vehicle to get to work to do it, Yes.
They live primarily in California, how can we be certain they don't commute on a bicycle built for two? I think we need dev input to nail this one down.
Given the location of the SOE Daybreak headquarters, even if the dev's chosen method of transportation was a bicycle (single or tandem), said dev would likely need to fart somewhere along the commute to (or from) work. Therefore, since methane gas (which is a primary component of flatulence) is considered a hydrocarbon... the answer to your original question should still be a "yes".
