So that’s a car getting 25 mpg driving 25,000 miles, about 2 years for many. Do they look reasonable for amount of dirt trapped? (Doesn’t explain difference in 2 engines)
I don't really know what "good" looks like. I was posting more as a PSA. I believe my conditions are relatively optimal as I always use good fuel from a reputable marina.
Given how inexpensive the knock-off filters are, and how easy they are to change, I will continue to change the filters 2x per season.
