Makes sense.

The other night I noticed that Widman has updated his Oil for Corvairs paper and now is a little more generally about flat tappets and includes more on High Temperature, High Shear viscosity (HTHS). Limited comments about specific oils but Dr Charles should look at page 24.

He has also added a paper on oil for Minis (real minis) which is worth glancing at just for its introduction to gear oiling.
