[SEL] Non-detergent Oil--The Rest Of The Story

[Jim Kirkes]

About ten years ago the list nearly went to war about 
weather non detergent or detergent oil should be used in 
old engines.  Some holding that the engines were designed 
for use with non detergent oil, others stating that it was 
foolish to use old fashioned oil and engine life would be 
prolonged with detergent oil.  I see that opinions have not 
changed much.

Rick & Dave:

Methink that in the days these engines were working for a 
living,
they probably ran hotter and with leaner mixtures than now, 
when
they are retired.

Also, back then, I kinda think that they were torn down
periodically to remove carbon and other clag left by the
non-detergent oils of the time.

Nowadays, running rich and cool and without the benefit of
detergent additives, carbon is likely to build-up in ring
grooves, causing ring binding.

I could be wrong here (and probably am) but that's my 
opinion,
worth exactly what you paid for it.    :-)
