Danny Kiwi 0 Report post Posted December 7, 2003 Just how importent is changing the Fuel Filter in the Big Six My 535i has not had a filter change in almost five years.. (Hiding Head in Shame)..but now seems to be running like a pig could this be the cause.. Quote Share this post Link to post Share on other sites
Grant 4 Report post Posted December 7, 2003 I have never changed mine, and have had my E30 325i (smaller 6) for almost 5 years. It is more of a problem if you let the tank run really low on fuel often, then you end up with the sh*t at the bottom of your fuel tank going through your fuel filter....but if it is running rough, it could be an option to look at replacing, but it is no use replacing it if there is nothing wrong with it.

Cheers Pretty much what Grant said, However I would include it in some kind of routine maintaince schedule.. 100000k perhaps.. Maybe even less. Quote Share this post Link to post Share on other sites
Guest michael_xb Report post Posted December 8, 2003 year if you run it empty sometimes then all the crap in the tank will go through the filter, i found that my standard one was so full that the petrol just coudnt get through and youd have to let the bits settle to get the car to start Quote Share this post Link to post Share on other sites
Gus 5 Report post Posted December 8, 2003 excuse my stupidity...but when your nearing a filter change...would it not be better to run it empty...thus clearing some of the crap out of the tank...or would this not achieve much and just clog up the engine....where its harder to get it out of....is there any other way to clean some of the crap out of the tank?

Grant 4 Report post Posted December 8, 2003 short of removing the whole fuel tank and cleaning it out, I don't think so....but that is what the fuel filter is there for, so I wouldn't worry too much about any crap in the bottom of your tank.

But it floats up, its pretty hard to get crap in the motor gus, how would it get through the injectors? Quote Share this post Link to post Share on other sites
