AllData Editors Note - Ford does not provide a cranking pressure specification, only an acceptable range.

Compression Pressure Limit Chart.:

The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75 percent of the highest reading. Refer to the Compression Pressure Limit Chart.

If one or more cylinders reads low, squirt approximately one tablespoon of Super Premium SAE 5W30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G on top of the piston(s) in the low-reading cylinder(s). Repeat the compression pressure check on these cylinders.
