I've removed old car oil from both cast concrete flags/slabs and some sort of natural stone using the method below but not specifically teak oil from slate.

Wipe off excess oil with dry cloths
Smear biological clothes washing liquid over remaining stain
Cover with a bowl or plastic sheet or similar and leave for 2 or 3 days
Method only works well if liquid is kept moist
If liquid dries out, spray gently with water to re-moisten but don't flood it
After 2 or 3 days, wipe away liquid and wash area with water (hose or brush). You won't need to scrub - the detergent has already done the job, you're simply washing away detergent residues.

Obviously, do this only when dry weather is forecast unless you can lift the slab and clean it under cover.

I've used this method many times on a driveway and it always works really well even on oil that's soaked in. Beware though that the treated patch may end up much cleaner (and therefore lighter in colour) than the surrounding area.
