anyone here ever use that seafoam stuff?

6MT

It's snake oil. I've sold that junk for almost 20 years now. I'll never use it. Here's a good example of why.... I had the rep come in to show us this stuff. He said that it would completely clean fuel injectors. So he tried it on my manager's Tahoe. After he was finished, the engine wouldn't start. Fault codes from the ECU read misfire on all cylinders. So we cleared the codes and waited an hour. Tried again to start it..... nothing. We had to change the spark plugs and clean the now fouled injectors with our professional cleaner in our shop.

There is one good thing about SeaFoam though..... it will clean the bugs off your bumper really well.

to me that seems like your manager had something else wrong with his tahoe beforehand as i have used seafoam on both my previous V6 altima and my current 4 cylinder cobalt and never and i mean NEVER do that to either of the cars i have used it on. Alot of V6 altima owners on the nissanclub forums will swear by it too as it does a good job of cleaning out the carbon deposits in the engine from using cheap gas so in my opinion it is a fairly worthwhile product, but as for using it on a 370Z engine who knows what effect it may have if any.
