The Phil oil works well but in the cold winter might be a bit thick. Your Mobil 1 will also work well: the detergents will not affect it at all. Lighter oils do tend to leak a little faster from the interlocking metal seals so you might have to top up more frequently. I made my own from a can of Mobil synthetic turbine oil with a small dose of some synthetic rear axle oil I added for EP additives. Works great, but not economically practical unless you're lubing a LOT of bikes.
