I agree. I run 30W in mine. That is what was around when these engines were designed. Synthetics in a newly rebuilt engine slow down the break-in period. Also, make sure the crankcase is not overfilled.

For what it's worth, when I worked for Ford, 1 quart of oil consumption per every 1,000 miles was considered normal on a car still under warranty.
