As title,
Does anyone ever use engine treatment/injector cleaner stuff ?
Is it safe to use on a Subaru or not / Is there any point in using it ?
What stuff do you use ?

Cheers
Marc.

IMO it has little effect...Probably won't do any harm though.

For a proper job, you should remove the injectors, then have them ultrasonically cleaned + flow tested.

i should imagine it would make more of difference on older cars as the injectors would have more carbon deposits on them.

i had my MY99 done at TSL when it was 4 years old, can't say it felt any better or worse to drive.
