Engine Longevity

["Charles E. Whitney" <clncrew@erols.com>]

Hello All,

What is a good average life expectancy (in miles) of our dear T-3 motors
if kept stock and well maintained at factory specs?

Next, my '67 Square has the stock motor, dual carbs......  It has been
well taken care of by the one PO (as attested to by the dealer stamps in
the owners manual) AND myself.  It has 64K miles and has used 1/3 quart
of oil over the last 3K miles.  Is that usage low, typical, high?

Thanks,

Charlie
'67 Square
