Hello there,

I don't think it is effective thats why I don't use it on my fuel injected car.
I could recommend to look for a shop which is equipped with a pressurized injector cleaner just like Carbon Clean before. We used to have an equipment like that when I was still working with Powerasia- Automechanika. Better to have your car tuned up with shops equipped with diagnostic scan tool. I could recommend shops just in case near your area.
ty sir, baka may marecommend po kayo sakin within las pinas area. may nakita din ako ultrasound injector cleaning ba yun sa goodyear servitek? maganda din ba yun?
