I have used 29gx1/2" pins for oil based test. It injects quite easy, on account of the narrow diameter of the syringe barrel.
Now, where the difficulty arises, is loading the syringe. Drawing up the oil takes a long time. To get around that, one loads into a standard 3ml syringe, and then carefully "back-loads" the slin pin. Sounds tricky, but it's actually quite easy. Just be careful when you reinsert the plunger, as you need to simultaneously invert the slin pin, to allow the air bubble to rise to the needle end, so that you don't lose some oil in the process...
