What is the GM fuel filter change indicator measuring?
Is it based on an alogarithm of operations, or actual sensor measurements of filter performance?
Algorithm I believe, like the oil change is calculated. I’ve had fuel limps in the 50-60 percentile before, so it’s not volume used or pressure related.
