     We occasionally see temperatures below freezing here in Phoenix, more 
often in Tucson, and certainly in Flagstaff.  20-50 oil is ideal for our 
climate extremes.  My 2000 Toyota pickup still uses no oil even after 190,000 
miles, and will probably continue to do so as long as I do all the mechanical 
work on it.  If the engine ever gives out I'll have it short-blocked with a 
rebuilt engine from Japan.
