Anyone ever used it on their engine. I wanted wash the engine. I planned on getting some simple green but I let the parts guy sell me on the B52. I finally read the directions in order to wash it today. There's a warning on the back that says avoid contact with aluminum. I know the pistons are, is there anything else?

 

yes your innercooler tubes,im sure theres more,just cant remember right now.



EDIT:turbo,turbo pedestel.Others will chime in.

 

turbo, turbo pedestal, fins on you cooling system, IC tubes... who knows what else. I don't think I'd use it. I used Simple Green and with a little elbow grease it worked really well and I wasn't worried about it damaging anything. Make sure to cover your air cleaner, power steering pump, alternater and fuse box.
