How often do you Duramax owners change your fuel filters????

 

[tmk50]

I change mine every 10,000 miles or so.

 

[SledFreakM1000]

Does it make a difference if the truck is stock or not??

 

[revrider1]

I change mine with every other oil change, no it doesn't matter if it's stock or not

OK im brand new to this diesel truck stuff, so how often do you recommend changing the oil

 

[Super B]

I change the fuel filter on my Dmax about every 15K. Oil I change about every 10k. More if I do a lot of towing.

 

[buck50]

the recommended interval is 25 000 km for fuel filters

 

[stalefish_132]

i change oil and filter every 8-10,000km ( 5-6000miles) and fuel filter every 15k or when it plugs up. duramax's like clean fuel, dont skemp on the filter

Fuel filter is reccomended to be changed every 15,000 miles

If the truck is hopped up with a chip and intake I would only go 5000 miles max on an oil change but the fuel filter will not change, still at 15,000 miles.

If you do a lot of towing or off roading you should not go over 5000 miles, if you are just mall crawlin you can get 7500 miles Max.

all my dmax trucks i change oil every 5k miles and fuel filter every other oil change along with air filter, saves on fuel and injectors

 

[Rmk900rider]

I change my oil every 5k miles and fuel filter every other oil change

 

[Supplicate]

I changed mine every other oil change and used Napa Gold.

When it says "Oil Life - 0%" I change the oil.
When it says "Fuel FIlter Life - 0%" I change the filter.

 

[stalefish_132]

When it says "Oil Life - 0%" I change the oil.
When it says "Fuel FIlter Life - 0%" I change the filter.

at around 42-43% oil life is usually around 6000miles on my truck, my dad went by the 0% oil life once, looked on the clock, it was around 11,000miles i think. won't do that again. you could probably get away with extended oil changes but is it really worth it? mine has 398xxxkm or 242xxxmiles on the clock and nothing but routine maint.

 

[Backcountry]

I change oil around 5K if I have been towing, around 7500K if Ive been cruising around town. I change fuel filters every other oil change- so every 10 to 15K. I also use Stanadyne as a fuel additive.

 

[Barnes]

Oil change every 5 (synthetic oil) and fuel filter every 10. Ally external filter every 25.

 

[2XM3]

oil at 10,000 or so, fuel at 35,000 but I have a cat filter kit for the fuel, the filter is 3 inches around by like 18 inches long. Best thing I ever put on. Finer screen than the factory too.

 

[IDAHDOO]

When it says "Oil Life - 0%" I change the oil.
When it says "Fuel FIlter Life - 0%" I change the filter.

This is what I do. I have heard it is off crank revolutions NOT milage. I have not checked what it actually is in miles.

I dont think the mfg's would suggest anything less/more than the minimum required intervals.

 

[Himark]

once a year unless you are running bio-diesel and you may have to change it every tank with that stuff.
