Hello grease experts,
I'm new in this forum and this is my first post. I start direct with my general question.
Can I mix grese with oil to lower the NLGI rate?
I need some NLGI 0 or 1 grease with base oil viscosity 100...220 . The grease will be used in bicycle internal gear hub. I need small quentity e.g 0,4kg cartridge. Unfortunatley NLGI 0 and 1 greses are coming in 18 or 150kg packages.
I'm a little bit confused.
1. The lubrication experts completely refuse to do that E.g look at article in machinery lubrication "stop pumping oil in bearing grease". The authour is contributor in this forum too

2. The OEM is mixing old grease with oil. Look at http://www.shimano.com/publish/content/g...oadFile.html/07)%20Maintenance%20Oil.pdf
I want to switch from OEM products to Mobil products. They are cheap reliable and open. They gives plenty of specification and test data /e.g. ASTM D..../
In contrast to Japan made deeply keep in secret OEM - Shimano nexus grease and oil. Secondary I don't like the grinding noise from low viscosity OEM base oil.
.I want to mix Li complex PAO based MOBILITH SHC 100 NLGI 2. and Mobil SHC 100 oil. I have both .
They mix together quite easy and base oils looks to be the same. I need such a grease for my hobby - bicycle with internal gear hubs. It is closed but not sealed construction from 3-4 planetary gears needle bearing on satellite gears and 3 ball bearings for the wheel axis. The whole gear has 130mm diameter and it rotates between 0...400 tr/min. The gears can be completely disassembled and degreased.
The OEM manufacture Shimano offer the following lubes
1. Shimano nexus grease - Seems to be NLGI1 or 0, The base oils seems to be light. I suppose lower than 100. Price 15USD/60gr.
2. Shimano mantainance oil - once per 5 year you have to dunk the complete gear in this oil. Price 100..150USD/ 1l.
Completely disassembled internal gear hub is available here.

What do you think can I mix them?

If needed, I'm ready to provide additional information.
