Fuel Filter Change Intervals?

On my VW it's supposed a lifetime unit

Changed at 30K.
 
There's no mention of mine in the maintenance schedule, so you basically do it if there's a problem, or whenever you feel like it. I shoot for every 30k. I was reading GM Techlink this month. Apparently GM is starting to move to a non-servicable filter on some of it's models. The filter will be incorporated into the fuel sending unit.
 
Most cars recommend 30K. Mercedes ML320 recommends every 90K, but they're beefy, expensive, and hard to get at.

Some report that a neglected fuel filter will result in dirty fuel injectors. I'm not sure that's true. Wouldn't a dirty fuel filter act like a used air filter and become more efficient at trapping contaminants?
 
A dirty fuel filter strains your fuel pump.My old 320i fuel pump was pretty loud until I swapped in a new fuel filter.
 
Changed my F350 at 60,000 miles. My daughter's Corolla (now dead and gone) clogged and got changed at 90K, but went to 250K without any problems. Haven't changed the Subaru (24K) or MPV's (60K)yet. Really believe that overall gasoline storage has improved and our gas is cleaner when it comes out of the pump. I can remember when gas filters clogged at 12K or even less at times.
 
I bought my 92 mirage at 63k miles and in 1998. I haven't changed the fuel filter yet and I got 123k miles and six years later. I do have the fuel filter though, just never got around to it. when my girl gets a digital camera in a week for her birthday, I'm gonna take pics of this fuel filter. I believe it's 13 years old.
 
My last car, Toyota Cressida was changed at 190,000 and just did it as part of the 200,000 mile maintence. I plan on maybe 100,000 mile changes on my newer Honda Accord and Mazda Miata. If you use a car a lot and it is constantly getting filled up should last a long time. On my TR3 it gets changed every few years which is less than 10,000 miles.
 
On my 1992 VW Diesel the fuel filter is supposed to be changed every 2 years/48,000 km. There is also a water seperator on the bottom of the tank you can drain whenever you feel like it. The filter has the returned fuel pass through it depending on temperature so it is kinda expensive.

Definately don't wait 10 years to change your filter, you will have a huge mess fixing the lines that break. You'll have to buy those fuel line repair kits that have a metal fitting crimped onto a rubber line.

Yeah, I guess I'll bite the bullet because at about 50k miles I won't be able to sleep knowing that the filter is dirty. BAD, BAD Chrysler engineers----->

I think that's what DC is doing. Anything to make the product unserviceable for the DIY'er.

Yes, I remember in the 80s living in Miami during the "great tank change-out" when pretty much all the old steel tanks were replaced by fiberglass (?) units. I don't know if it was an EPA rule or state rule but you would see the old steel tanks pulled out and they generally looked pretty rusty. I would think the inside was no better being gasoline does not prevent rust.
 
I wonder about these lifetime units?

I had trouble out of both my vehicles using local Shell stations. Fuel filters looked awful. I started using different gas and no more problems in 2 years.

I change at 30K just to be sure. They're cheap on my rides.

Some gas stations and distributors just don't maintain their tanks.

I just remembered that my 1987 Ford E-150 also has a permanent filter. It is part of some kind of booster pump under the drivers door. I don't remember if it has a normal filter or not. 130K km and still going strong...yep, just 80K miles on the old girl.

Let her rust in pieces.

haley10,

Talk about not maintaing tanks. I saw a buddy getting gas at a KwikFill station. I stopped to tell him that their gas is horrible(around here anyway) and he pointed to the bottom of the pump. Inside the pump was a spin on filter of some sort that was rusted and had drops of gasoline dripping out of it and onto the ground. The attendant didn't really seem to care.
