Hi Scotty and All,
Ive seen your videos and started using royal purple fuel injector cleaners on my 93 Camaro and it's running better. Recently I noticed my wife's chevy spark w turbo has been accelerating slow and it has ran smoother after I've used the cleaner once in my last refuel. Should I use it again on its next refuel and how often can I use it? And how often is too often that it'll damage any car?
Thanks in advance!
Well the only thing it hurts is your wallet. You don't need to keep cleaning them. Maybe once a year or something
