It's about time to restock my shelves. Do filters ever realistically go bad? I've put 5,000 miles on my Dodge thus far which multiplies out to 15,000 this year. I'm changing the fuel filter every other oil change. It's due for a fuel and oil filter in ~4,000 at 265,000. Am I stupid to buy up 7 oil filters and 3 fuel filters to last me to 300,000. I have the next interval covered. That should cover me until 2015.
I hear the hype about filter prices going up too. True? It also always ends up that I have time to do this stuff at about 9 at night and 250 miles over the interval, so I like to have a stash.
Opinions?
