I use Seafoam specifically because it's a fuel stabilizer as well as a cleaner that has performed flawlessly in my cars for years.If you run top tier 91+ gasoline and the car is ran regularly then you do not need any type of fuel injection cleaner additive. Now if neither of these happen then it would not hurt to use something especially right after the car has not been run for a while.
Due to the pressure and heat a GDI injector sees there is usually very little buildup compared to older conventional injector types. I've seen em flow tested, cleaned, and flow tested again with very little change in output or spray patterns. GDI injector that has never seen any type of cleaners that is.
What makes you say this?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.....
I am writing in general issues that I had with different cars before. I try to stay away from that.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.
Interesting you say that because I've been using carb/ fuel injector cleaners since 1980 and in every car I've owned. I've never had a fuel related issue with any that I've used and that means pretty much everything you see on the shelf at most auto parts.I am writing in general issues that I had with different cars before. I try to stay away from that.
