IMO use 0W30 if you never track/ drive really hard for long. 0W40 if you'll put the engine under stress and really heat it up.

Once a year before the oil change I put Techron through all our cars. Carbon is more likely to build up in cars that do mainly city mileage; am not sure if that applies more so to short commutes.
Tell me more about the ELM237. do you have to have a laptop in the car or you can view it from your dash/phone/nav?
