I have a Hyundai Accent, fuel injector cleaner haven’t been put it in for over 20xxxkm. My gas mileage was starting to get horrible so I went and got some Gumout high mileage and accidentally put the whole bottle (rated for 72L) in my 32L tank. I filled it up from empty. Will this cause any damage to my car? Thanks.
It damaged your wallet. Gumout HM has 1% of PEA, the cleaning agent. Redline has up to 50%.
