Olive oil with a drop of lemon juice is fine for sealing wooden worktops in kitchens. i sue it on my beech counters. However, for external use, teak oil is best as it absorbs and preserves well without making a crust and is easily cleaned up in spring.
I like the golden glow of my teak table but it's too big to take under shelter so it gets left out all winter in temps down to the late -20sC. last year, I was fed up of doing the annual spring clean with the sander and oiling it so I spent extra time giving it a coat of special wood preservative with a pale grey patina an dthen sealed that with a special coat of protector.
Lo and behold, these too products are not good down to -28C and have flaked off or grown algae so I've had an even longer job sanding it all off and have gone back to feeding with teak oil. Next spring will be the last so I know it has a good seal of oil and then it can age with grace and go a natural silvery grey.
