Hi,
Did you see the posting on rings yesterday? If had a good explaination
as to oil useage, ring combinations, and RPM. A lot depends on the RPM
you're running your engine at. If you're staying down in the 3000/3500 RPM
range ( who is...) your consumption should be less than if you're doing a
lot
of 4000/4500 RPM freeway cruising.
Actually, if I remember correctly, most of the vehicles designed in the
60's used a quart of oil per 1000 to 2000 miles of normal driving. My
'72 B, bought new in '72 used a quart every 1500 to 2000 miles, which is
about what you're seeing.
IMHO, don't worry about it.
Harlan.
