MG was more tolerant of oil consumption than we are today. "Sipping" could
mean 400 miles to a quart, once upon a time. Have you determined that the
oil is passing the rings, or coming down past the valve stems, or not dripping
from seals or pan or other connections? I am sceptical that on this newly
rebuilt engine that it's rings or cylinder problems. My MGB has almost a
thousand miles since its spring time oil change, when Brad Penn 20-50 (the
high ZDDP stuff) was put in, and there has been only the slightest drop on the
dipstick. I am suspicious of troubles, as it does not seem to be burning
enough. How did the LR guy bore cylinders other than round?Bob

Yes! Ok, I've had my 62 mga engine rebuilt 3 times by "experts". The current
iteration seems solid - put a couple thousand miles on her. But she sips oil
modestly. The guy who did the machine shop work for my 59 Land Rover told me
that most machine shops and rebuilders machine the cylinder walls wrong.
They make the cylinders round instead of slightly oval toward the bottom of
the stroke which considers the pull and push rotation of the driveshaft and
connector arm. Seems reasonable to me.
So the question. Should I increase the viscosity of the oil to allow less
oil burn, and/or, go to synthetic which won't burn off?
Also by now, I'm figuring she has finished running in and plan to change
oil/filter.
