From Marc Haibec website.
Anti-Drainback Test Results
The filters were removed from LT5 engines 8 hours after shutdown. The oil to weight
ratio is the weight of the retained oil expressed as a percentage of the total weight of the
filter and the oil. The testing was performed with Mobil 1 10W-30 oil. Mobil1 10W-30
oil weighs .94 ounce in mass per fluid ounce of volume.
Filter. Weight when new. Weight after 8 hours. Retained oil weight. Oil to weight ratio.
PF970 14oz. 25oz. 11oz. 44%
PF970C early 15oz. 18oz. 3oz. 17%
PF970C late 15oz. 20oz. 5oz. 25%
PF970C blue 14oz. 22oz. 8oz. 36%
Bosch 3401 13oz. 22oz. 9oz. 41%
Mobil 1 207 17oz. 21oz. 4oz. 19%
Recommendations
The old blue PF970 was the best performer in this test. However, it is no longer available
from AC-Delco. The Bosch 3401 and the blue PF970C filters are about equal with very
good anti-drainback performance in this test.
