[Farmall] Farmall H Questions,

Castrol is good but Pennzoil and Quaker state are paraffin based oils which 
 I don't recommend for anything especially in cold weather when you don't 
get the  engine up to full operating temperature..

With  respect to possible rings sticking, I'd suggest putting an once 
or two of  Rislone in each cylinder and letting it set a day or 
so.  I've done  this on several tractors and compression can 
improve.  Lots of smoke  for a few minutes so be kind to your neighbors!

With respect engine oil  -- 10 - 40  detergent (Pennzoil or Castrol 
usually) has worked well  for me irrespective of the amount of 
deposits present.  The removal  of "crud" has never been too 
impressive in my admittedly limited  experience.  The oil has darkened 
fairly fast but no big chunks or  filter plugging has occurred.

If memory serves correctly, Karl Olmstead  tows his F-12s (and 
others?) around for a short while with diesel in the  crankcase for 
initial "crud" removal.  Maybe Karl could comment on  this.
