My girlfriend has a 2012 kia Forte ex. NON gdi. I'm aware of the tsb and have been using the oem filters. I believe oem spec is for 7500 miles though. I've really been wanting to get a fram ultra with either m1 ep or Castrol extended to get closer to 15k miles. My girlfriend isn't good about letting me know when it needs changed so I want to be able to go for a while if it happens. Would you think there will be an issue with running a fram ultra instead of an oem?
