Doesn't really matter what a dealer suggests.

One needs to take into consideration what sort of fuel they are burning and how much of said fuel(s), then make an educated decision.

The interval also depends on the year/model of truck, as the fuel systems differ greatly in sensitivity. While we change out the fuel filter every 7,000 KM on a friend's LB7, I only slap a new one on my LML every 30,000 KM. His LB7 has "finicky" injectors and he runs nothing but died diesel (or the junk we use in equipment on site). My welding rig on the other hand, only gets fuel from the popular gas stations in town.

Check your owner's manual for a GM suggestion, then apply above theory.

No rocket science involved.

This is why I preach better filtration because that stuff is fatal if it gets through your filter. I am a true believer in better aftermarket filtration. Things like the Nicktane Auxiliary Filter and the Nicktane Cat adapt. Those with a Fass or AD lift pump get better filtration. No matter what you choose it is money well spent for your Dmax.

As far as filter changes on my 05 that I just sold we changed every 15K miles with the oil change. Make it simple for you, change your Allison spin-on filter and fuel filter at the same time. Many do a 10-15k mile fuel filter change.

I noticed that everybody saying the OP is crazy for going that long before changing does not own a LML. In their older trucks they should change their filters sooner. I agree it all depends on application and good judgement, but changing your fuel filter ever 6K or 10K in a LML truck is a flat waist of time and money. The 100K 5 yr. warranty is based on what that DIC displays. My truck is at 26K and my DIC still says 50% fuel filter life left. I think Ill be changing it soon even though I think it'll be a little unnecessary. The LML is designed to go further on oil and fuel filter life and GM bases their 100k 5yr warranty off of this system and thats good enough for me. If GM weren't possitive that the LML could do what the DIC displays to it's owner, they wouldn't do it, cause after all, within that time, they are the one footing the bill for a failure. As long as the owner isn't stupid enough to poor straight water into the fuel system, the DIC should be sufficient in most cases.

I want some of this super high quality clean fuel you are running. You are running the same fuel I am and the next guy. Just because you have a LML with a warranty doesn't mean your fuel filters last longer. I don't trust the DIC nor do other members on here. 40,000 miles is a lot on one fuel filter.

A 40$ fuel filter is a lot cheaper than a CP4 pump or injectors. Just saying...

If you get dirty fuel, and it damages the injection system-- GM will NOT warranty the damage. Just saying.

Just change it every other oil change.

Well then maybe you guys should change your filters after every fill up? From the sounds and concerns of it, sounds like you guys believe your buying Mexico quality fuel. personally I believe in about 25,000mi intervals. Coarse I leave my truck stock, I don't put all those power adders some of you guys do.

all diesel can be considered ''dirty'' its a bi-product of gasoline.. it doesnt matter how often everyone tells one another they should change fuel filters.. more filtration and quicker intervals between changes will never hurt a thing, cant do no harm, it can only help, with or without additives.. i think we all take a vow when we buy these trucks that we know our parts most likely arent going to be cheap in the event of replacing things.. id rather spend 40$ and change my filter more often then spend the money it will cost to replace fuel system parts.. the filters are there for a reason and they r made to be changed, thats why they screw on.. lol to each his own. im sticking with the way i been changing mine
