Here in New England the oak door sill of an outside door takes a beating. Mine are scuffed and need refinishing. But what’s the best waterproofing for them? I want something that sinks in and doesn’t swell the sill so the door will be too tight.

I like a few coats of 1/3 boiled linseed oil, 1/3 spar varnish, 1/3 mineral spirits. Repairs easy with just an oil touch up.

Spar varinish works but only for a few years.. you have to periodically renew it. If you really want it to hold up use a paint instead.. one intended for flooring..
If you'er considering paint Benjamin Moore has an Alkyd Porch and Floor enamel that's pretty durable stuff. They also have a latex version which I have no experience with. If you want the woodgrain to show Sphere's treatment should work as well as anything. Regardless of your finish choice I'd consider a wood threshold/doorsill a routine maintainance item when you consider the foot traffic, abrasion from door seeps and dirt, exposure to rain, snow, ice etc.

This is what you need, and in a small quantity for doing just the exterior sills of your house.

It is a moisture-curing exterior urethane, tough as nails, and I have used it, and only for your exact application.
Available from my cousin's fine company, Woodworker's Supply. Google "woodworker" and you will find them.
