We were often asked this question by new owners in my days as a salesman for
S-T. With mineral oil being the only one available and with what the factory
(curiously) said was "considerate use" - meaning you didn't continuously 'red
line' the rev counter - oil consumption was anticipated as being one pint per
1000 miles at about 60,000 miles and always on a 20W/50. By that stage, the
piston rings would be less effective and the valve guides would be approaching
their life end. You'd certainly have been facing a full rebuild by 85,000.
These days with modern lubes and still using the latest spec mineral lube with
full oil and filter changes at 3000 mile intervals, I'd be looking at almost
doubling the figures above. My own 2500 injected engine was using less than
1/2 pint of oil per 1500 miles by the time I sold the car at 84,000 since the
rebuild - and most of that oil loss was from a pinhole leak on the front crank
oil seal which I never did get round to sorting.
