Gunk engine flush says on the bottle "not to be used with turbo vehicles"? Anyone used the German Moto engine flush on a SAAB?
I read a lot of great things about Auto-RX too, so I ordered two bottles that are still sitting in my garage. Mainly for the fact that I don't want to use until I have time to drop the pan right afterwards. One would think that anything flushed out of the engine will collect at the pick-up screen, so the screen should be cleaned after a flush.
