Neutra 131 or Seafoam?

[GimmeTorq]

Could these products be harmful to fuel system/engine components in the long run? I'm worried about rubber seals, fuel injectors, etc.

Seafoam: http://seafoamsales.com/pdf/trans_tune.pdf

I'm want a safe product that I can use regularly as preventive maintenance, to keep both engine and fuel system internals clean. From reading this forum, these seem to be the most trusted and effective, but I'm worried about long term effects. All opinions are welcome.

Thanks

Is 131 Neutra suitable for cleaning an automatic transmission? What dosage? How many miles before flushing? Any other instructions?

Bob would be the first one to tell you when you
clean transmissions it goes without saying you have clean the seals completely as well as metal parts. Transmissions develop seal leaks thats one of the things Auto-Rx does stop leaks.

I use Lucas upper cylinder lubricant regularly. I have talked to people who have used it for years and never had a clogged injector or rough running engine related to carbon or fuel system problems.

I have looked at my spark plugs after using the Lucas UCL and it does seem to burn very clean .
