Hi:

I'm buying a used boat with GM 350 gas engines. Any suggestions on
which fuel to use, regular or premium unleaded? Any thoughts on using
after market gas additives?

You aren't going to get any significant performance advantage with
higher grades of gasoline, so regular is the way to go. Not to
mention cheaper.

As to additives, for regular use, the new Sta-Bil - I add it every
time I gas up. The new Sta-Bil formulation has an ethanol stabilizer
in it (I think ithey came to an agreement with E-Zorb) and while phase
seperation hasn't been the problem it was predicted to be, water in
gas can be a problem - I'd use the Sta-Bil at every fill or when you
add gas. I add it to everything here from the two stroke garden stuff
to the lawn tractor.

As to other additives, don't waste the money.

Phase seperation hasn't been a problem, you can't be serious. Their's
been many an engine, outboards even more so, that have had all kinds
of problems, and phase seperation has been identified as one of the
biggest problems. Check with BoatUS, ethanol has been nothing but a
problem. If we're luck they will keep it out of marine diesel.
