I heard you should change Fuel Filter about every 30,000 miles. For many people this is once every year, or every 2 years. But if you drive much less miles like I do, I heard you should change filter every few years anyway due to buildup.

Since I changed the Fuel Filter on my Blazer 4 years ago I have only put 12,000 miles on it, and was wondering how long you think I should wait to change it again?

I recently changed the Fuel Filter on my other car for the first time ever, only because it was 5 years old, also was under 30,000 mile recommendation.

So you think I should wait another year on Blazer, which would be 5 yr/15,000 mile for Fuel Filter change?

Those scam artists at oil change places try to get me to do it every time I go, but I always say no.

 

Have you read your owner's manual? I would not go over 3 years since you are a low mileage driver.

 

its good to change offten to save on injector problems.the filter is chep but injectors and all outher parts are not.be good to your little blazer and it will last a long time
