I drive a 2014 ford 6.7. Ford came out with their special
-F1 specification that basically requires over 1000ppm Phosphorus (basically to combat valve train wear).
What would cause my Phosphorus levels to drop from 1183 to 465ppm. First sample was at 7,847 miles on oil and the second sample was 14,544 miles on oil.
My thoughts:
1. Testing error
2. Using a different product to top off oil level
3. Engine consumption
4. Drop out of suspension and removed by the bypass filter.
