Berryman's B-12 Chemtool, is it safe?

I have seen this stuff mentioned a few times, mainly at the "Bob IsThe Oil" Guy forums.

Is this stuff safe for the Nissan's fuel system? Car is a stock '92 S13 with over 211,000 miles. Thanks.

isnt that stuff like the knockoff version of Seafoam?

uhm, maybe because they don't drive Nissan's! Not many of them at least.....especially 240's. What's good for one car may not be for another, ya know?

I'm thinking about trying it before an oil change, and when I plan to do some substantial driving, so I can hopefully work it through fairly quickly and not have it in my car too long. It seems to be fairly safe, but I just wanted to make sure. I plan to run it in my gas tank and possibly do some other various cleaning with it, but mostly in-tank as a fuel system cleaner.

Thanks for the feedback.

*Edit* mrmephistopheles, could you elaborate a bit for me please? Like what did you use it for and what did you notice as a result? Thanks I really appreciate it!

I used that before not on a 240 though. That thing rocks (b12). Use in a very outdoors area. Not in a garage with the exhuast facing out the open garage door trust me. When I did this before in a gas station shop, so much smoke we cleared the area. But afterward the car felt 1000x better. This was like at least 8 years ago. Not sure when seafoam came out, but Berryman been out for a long time.

I used it on my blazer. I know it's not a 240, but I don't see why it would hurt a stock 240. Best fuel system cleaner I've ever used.
