Fuel additive

Does anyone use fuel additive in addition to the premium gas?

I run a can of bg44k through a tankful
and put 6oz of Seafoam through the
intake manifold just before each oil
change every 5,000 miles.

I occasionally add some Lucas Octane booster when it's rally warm and dry in the summer to help avoid super knock.. Cleaners don't really do anything since with direct injection the fuel in injected directly into the combustion chamber skipping the valves.
