Not obvious. There are other options. Oil, kerosene, citrus solvent, etc.

SORRY, I'M A NEWBIE, I didn't find Shimano instructions on how to lube the hub properly for wet climate. Instead, I found instructions on Sheldon Brown's and Aaron's Bike Repair websites. Not everyone is as experienced as you are!

Shimano Nexus SG-8R20 8-Speed Internally Geared Hub with Roller Brake
This hub was ridden less than one year in Seattle. Neither the shop nor Shimano used enough grease and oil for NW weather.
...
Unfourtunately, the only way to fix this hub is replacement. The hub shell bearing races were badly pitted. The hub functioned, but with a very loud rumbling noise.
2013 Update: Current Shimano production adds ample grease for most fair weather users. However, in wet climates we still recommend an initial weatherization/overhaul at 1000 miles. After that, every 3000 miles or 2 years is fine. Daily commuters should have their hub overhauled once a year regardless of milage.
Internal Gear Hub Service
I'm a daily commuter in
damp and rainy Irish weather. I don't want to risk having to buy a new hub after riding few years with cheap manufacturer's lubrication inside the hub.

Dan, thanks. I thought doing
this will ensure that the parts where grease didn't get to, will be 'washed' by this oil...

My hub is
SG-8R36, how to check if it's the base model?
Could you please comment the photos that I published? I didn't find anything strange inside, except oil together with grease made a weird coloured mixture and marine grease around outer bearings on non-drive (left) side became grey (but around opposite bearings is still green...).
