[AT] oil for old engines

There is a reason for not using high detergent oil in an existing old 
engine. In a newly cleaned old engine today's oils are fine, BUT, by woeful 
experience don't change engine oil from a non-detergent to new detergent oil 
without cleaning the engine up first. By that I mean removing all the 
parafin and crud residue coating the inside of the block.  I didn't and the 
end result was an oil pan full of sludge, plugged oil pump and loss of a RD7 
cat engine.
Delo ate up whatever it found and there was lots of it. Every oil orfice in 
that engine was plugged.
My two bits
