TF2 for me too. Which reminds me, I need to buy some more as I have recently dribbled the last of a 1ltr bottle, bought a fair few years ago, into the smaller squeezy nozzle bottle I use for applying it.
I have covered many, many thousands of miles on different bikes (MTB/hybrid commuter/best road bike) in all conditions and always found this oil does the job. Also pretty cheap when bought 1ltr at a time -

Bottle has changed a bit since I last bought some
It doesn't have an offensive smell?
