The stated oil change is indeed 3,000 miles however in my opinion this likely has more to do with the engine being newly designed. It would not surprise if this number changes over time,
for two months short of 10 years I drove 150+ miles round trip to work and back .... where was an Elio when I needed it .... at that rate, if they weren't cranked for anything but going to work, I put 3,000+ miles a month on my vehicles .... over the years I've seen the recommendations for oil change intervals bounce around all over the place .... with regular vehicles I've always changed the oil and filter every 5,000 miles .... during the years mentioned above, if the engine didn't overheat, I changed to a 10,000 mile interval with the filter changed at and quart of oil added at the 5,000 mile mark .... all I can say is it worked well for me and I do want to note again that rate I was still changing oil every 3 or so months
