A friend told me he puts fuel injector cleaner when he gets his oil changed. I talked to my uncle that knows quite a bit about cars and he said it is not good for the car. Can I get some help on this? If it's not harmful to the car. Is it bad to put in a wrx? I bought a bottle but was unsure if it's safe and safe with a turbo?
Can anyone give me the correct answer if I should or shouldn't use it?
