Star-Tron or Sta-Bil Marine

Both claim to stabilize the ethanol in the fuel. However, that Sta-Bil claims to also lube the internals to prevent rust from forming from the water suspended in the fuel. Anyone using the Sta-Bil? I have been using the Star-Tron, but bought a bottle of the Sta-Bil yesterday, I bought the marine formula. Opinions, thoughts? What say you?

I use Sta-bil Marine formula and have had no fuel related problems in the 200 Zuke, 70 'Rude or 25 Yamaha so far.

we reccommend startron, but have and sell both

I use Star-Tron. It says that it reverses the effects of E-10. I have not had problem with anything that has a motor and gas stored in it. That includes my riding mowers, push mowers, generator, boat in dry dock, boat in my garage, wifes scooter, etc.
