Anyone have any experience using fuel additives in their SVX? I noticed KC sells a Red Line "fuel system cleaner" for $4.25, wondering if it was worth trying?

Honestly? Well, these fuel additives are okay... but they really only make minor differences in the way the car feels. If there's some dirt on the injectors, then it's pretty good at cleaning it off... but there's a point at which the dirt gets so caked on that it can't be flushed without doing some major work. Honestly... you probably won't notice a LOT of difference... or any at all for that matter... but a couple of bucks might be worth it for peace of mind.

That's more of what I was worried about. Not so much being able to feel a performance difference but keeping things clean and avoiding major work. Thanks for the feedback.
