I have a 2014 Santa Fe that can't have the check engine light shut off unless the engine is taken apart and the carbon cleaned out of it. This is a problem with GDI engines. I can't afford to have the engine cleaned every time the light comes on in this vehicle and the new accent I just got. It's not covered under warranty. Can I run non ethanol fuel to help reduce carbon build up until I can afford to get rid of these vehicles? Thanks for any input.
