How often does a cars fuel filter need to be changed? My mechanic has told me every 30k. I'm due for one now and car has 141k. I've gone 30k on the current filter and it runs perfectly. Other cars I've owned, I've NEVER changed the fuel filer and they ran great until I got rid of them with 200k miles on them. so what is the best way to handle this...how often?
Is it really necessary?
