I suggest you to use high octane fuel and replace your fuel filter frequently. Injector cleaner is a fuel pump killer plus is going to damage every rubber parts like hoses, seals, etc.....

What makes you say this?
I've never heard of this and you'll get more damage from ethanol in your fuel than any purported damage from fuel injector cleaner. 🤷🏼‍♂️🤨

Hyundai's have no fuel filters to change unless you're describing the screen filter in the tank attached to the fuel pump. That's only replaceable when you pull the fuel pump from the tank.

I am writing in general issues that I had with different cars before. I try to stay away from that.
