I've tried seafoam in the fuel tank, and maybe i'm just fooling
myself, but i thought it produced a better result than most
additives. truly seemed to have more pep on acceleration.
next time i change the fuel filters, i'll throw some in there.

used it only once so far on an oil change so it's too early to
tell on that. but i think it might be a good alternative to say
using engine flush simply because the quantity seems more
reasonable.

now, whether it's good or bad for the engine -- who knows?
