Diesel owners Question

My 03 Duramax has had the fuel filter changed a couple times I think. Although the thing is a POS it still runs fine. I changed the primary fuel filter twice in the 5 years and 100,000 miles I owned my '11 King Ranch. If you get dirty fuel, a filter can clog within a very short period of time regardless of whether it was changed yesterday or 50,000 miles ago. I own about 20 diesels and as a rule they get fuel filters changed if they experience a lack of power. I believe a new clean filter will let larger particles of contamination through it than a used filter. I've never had an injector or fuel pump failure on any of these engines. I expect I could have said the same thing if I had changed filters on each engine once or twice a year instead of once or twice a decade.
