After bearing with the nasty manual transmission on my 2012 forte, my wife and I decided to trade it on new Kia Soul Base. What is the common experience with newer GDI or Hyundai GDI engines? This is my wife's car so it will mostly see short trip city driving. Should I go with a severe service interval of 3750 on conventional? Or should I use a full synthetic at 6 or 7k miles? It would probably take more than 6 months to put 6 or 7k on it. She commutes 6 miles round trip a day to work and we take some long drives on the weekend.
Plus carbon build up, is this of the past now? I read that timing has been altered so the intake valve wont get gumped up.
