RE: (ET) rear end oil change

For cold weather Mobile synthetic transmission oil is a must! It should
be 80 or 90 weight. Using 10/40 engine oil you might have a problem with
the thin oil leaking out of the case and seals. For sub zero use 10/40
might be ok. I noticed a big difference in performance with temps in the
low 40's using the synthetic oil.

Any new oil is better than old/low oil!

Mobil makes a transmission version of their synthetic oil.  It is
'lighter' (lower viscosity) than most 
transmission oils, but does NOT 'break down' into the component parts
like a blend, so the viscosity 
does not rise significantly over time.

Mr. Landis can answer for himself, but his controller uses set point to
determine whether to charge or not.  
As battery temperature changes, and as the cells equalize, the voltage
will change and the set point will 
be passed.  The charger will indeed cycle a number of times.
