If I went down to 320 that would make it easier for the motor but would there be a danger then of oil getting passed the shaft seals?

Any woodworking machine that's used tends to accumulate wood dust everywhere,
and that soaks up any oil just fine:-)

FWIW, this planer:

has a gearbox in the bottom for the feed, with a filler cap and a little
dipstick. I was giving it a little TLC (for the first time in many years), and
checked the oil level, and it was bone dry. It had been run like that in a
production setting, for very many years...

I'd consider flushing the gearbox, i.e. running it with a cheap(er) oil and no
load, and then draining that once the crud has come loose, and only then fill
the "good" oil.
